    Device for managing the mechanical energy of an aircraft, having a system for applying force to a control lever, aircraft and associated method
    The present invention relates to a device for managing the mechanical energy of an aircraft, intended to be placed in a cockpit of the aircraft, comprising:
    - a support defining a slide;
    - a movable joystick for controlling a variation of mechanical energy of the aircraft, movably mounted through the slide;
    at least one position sensor of the mobile joystick in the slide, capable of generating information on the position of the mobile joystick in the slide intended to be sent to a flight control center of the aircraft capable of being jointly piloted, function of the position information of the mobile joystick, at least one propulsion engine and at least one energy modification member of the aircraft.
    The aircraft cockpit is for example located in the aircraft, in front of it, or on the ground, in an aircraft remote control cabin or in a simulator
    Such a device is intended in particular to facilitate the piloting of the propulsion axis of the aircraft, by simplifying the task of the pilot.
    Generally, in aircraft, the propulsion axis is controlled by several controls, in particular by the throttles corresponding to each engine, and by the controls of the aircraft energy modification members, such as airbrakes and shutters.
    To modify the total mechanical energy of the aircraft, the pilot can act on the throttles. However, he can only view the result of his command in terms of acceleration and slope once the engine speed has stabilized.
    In addition, the perception of the variation of mechanical energy available in the aircraft at a given instant resulting from the commands available in thrust or braking is delicate, and is obtained only indirectly by observing for example the percentage of engine speed. on a cockpit display.
    To overcome this problem, US 8,527,173 describes a device for managing the total energy of an aircraft in which a joystick can be used to adjust a variation in energy of the aircraft, comparable to a total pseudo-slope of the aircraft. .
    On the basis of the energy variation command sent to the flight control center, the latter adjusts the engine speed of each engine and the drag to reach the commanded energy variation.
    In addition, a possible energy variation scale is displayed in the form of a pseudo-slope scale on an aircraft display. This scale is bounded upwards and downwards respectively by the maximum value and by the minimum value of energy variation which can be reached by the aircraft, allowing the pilot to assess the operational situation on the propulsion axis and energy variation availability.
    This visual information is very useful for the pilot. However, in certain operational situations, in particular when he has to control other flight parameters, the pilot cannot concentrate directly on a scale displayed on a display.
    An object of the invention is therefore to have a management device which gives at any time an indication of the situation of the aircraft in terms of propulsion in its range of capacities, when the pilot is not able to '' carefully observe a display in the cockpit.

    A first aircraft 10 provided with a mechanical energy management device 12 according to the invention is illustrated in FIG. 1.
    In addition to the mechanical energy management device 12, the aircraft 10 comprises several propulsion engines 14, organs 16 for modifying the mechanical energy of the aircraft 10, sensors 17 for measuring flight parameters, and a central flight control 18, suitable for controlling each of the engines 14 and the mechanical energy modification members 16.
    Each propulsion engine 14 is capable of being controlled by the flight control center 18, in order to cause a thrust force to evolve on the aircraft 10, increasing or decreasing the total mechanical energy of the aircraft 10.
    The mechanical energy modification members 16 are advantageously drag modification devices for the aircraft 10. They comprise, for example, air brakes, and / or deployable flaps. Each mechanical energy modification member is capable of being controlled by the flight control center 18 in order to cause a drag force to evolve on the aircraft 10, decreasing or increasing the total mechanical energy of the aircraft 10.
    Each propulsion engine 14 and each mechanical energy modification member 16 therefore constitute a source of variation in mechanical energy of the aircraft 10.
    The flight parameter measurement sensors 17 are able in particular to determine the position, the altitude, the air and ground speeds, as well as the air and self slopes.
    The flight control center 18 comprises at least one processor 20, and a memory 22 containing a plurality of software modules 24 to 28 suitable for being executed by the processor 20.
    The memory 22 contains in particular a module 24 for developing the controls of the motors 14 and of the controls of the mechanical energy modification members 16.
    It advantageously contains a module 26 for calculating a quantity representative of the variation in mechanical energy of the aircraft as a function of the flight parameters.
    It also contains a module 28 for controlling the position of a mobile joystick 30 of the energy management device 12, capable of defining a position of the mobile joystick 30 representative of the situation of the aircraft 10 in its range of energy variation capacities.
    The command development module 24 is suitable for calculating the commands of the motors 14 and of the energy modification members 16 on the basis of a setpoint received from the energy management device 12, when the aircraft 10 is in manual piloting mode, or on the basis of a command received from an automatic piloting system, when the aircraft 10 is in automatic piloting mode.
    The module 26 for calculating the quantity representative of the variation in mechanical energy is for example suitable for calculating a current variation in mechanical energy of the aircraft and a range of variations in mechanical energy capable of being reached by the aircraft 10 at each instant, as a function of the flight parameters obtained from the sensors 17, and of the operational situation of the aircraft.
    The operational situation of the aircraft 10 includes in particular the evolution of the aircraft 10 on the ground or in flight and the equipment available, in particular the number of engines 14 and the individual thrust developed by each engine 14 and the number of members of mechanical energy modification 16 and the position of each mechanical energy modification member 16.
    The magnitude representative of the variation in mechanical energy is, for example, a total pseudo-slope, as calculated in US Patent 8,527,173 to the Applicant. This total pseudo-slope is defined as the ground slope, which under current conditions, leads to a constant conventional speed.
    The total pseudo-slope / is for example calculated by the following formula;
    r so i +
    T Jz = cste ^ V air dz = r so i + k
    Vc = cste where Ysoi is the ground slope of the aircraft 10, V S0 | is the speed of the aircraft 10 relative to the ground, V air is the air speed of the aircraft 10, V c is the conventional speed of the aircraft 10, g is the acceleration of gravity and z is the aircraft altitude 10.
    As will be seen below, the module 28 for controlling the position of the movable lever 30 is suitable for developing a position command for the movable lever 30 as a function of the current variation of mechanical energy, and of the range of variations. mechanical energy likely to be reached by the aircraft 10.
    The calculated position of the movable lever 30 reflects the current variation of mechanical energy of the aircraft 10 in the range of variations of mechanical energy capable of being reached by the aircraft 10. This position is designated as a position of " mobile neutral ”, and varies over time, without user intervention depending on the evolution configuration of the aircraft 10, in the autopilot mode.
    The limits of the range of mechanical energy variations likely to be reached also vary over time depending on the situation of the aircraft (in particular position, speed, attitude, available thrust, available drag, etc.).
    Maintaining the current variation in mechanical energy of the aircraft 10, and therefore the position of the mobile neutral is advantageously controlled by the autopilot system in autopilot mode.
    The variation in mechanical energy of the aircraft 10 can also be adjusted manually by the pilot by moving the movable lever 30 away from the position of movable neutral in order to define a new setpoint for varying the mechanical energy of the aircraft. 10 desired, within the range of variations in mechanical energy capable of being reached by the aircraft 10.
    Each position of the movable lever 30 then corresponds to a setpoint for varying the mechanical energy of the aircraft 10.
    With reference to FIGS. 1 and 2, the energy management device 12 comprises a main energy management system 32 comprising the movable lever 30, an auxiliary system 34 for individual control of the motors 14, suitable for use by the user in the event of failure of the mobile controller 30 and a light display system 36, visible in FIG. 8, suitable for giving luminous indications to the user of the mobile controller 30.
    With reference to FIG. 2, the main energy management system 32 comprises a support 40, intended to be fixed in the cockpit of the aircraft 10, the movable lever 30, movably mounted in the support 40 and at least one sensor 42 of position, intended to measure the position of the movable lever 30 relative to the support 40.
    According to the invention, the main energy management system 32 further comprises an active system 44 for applying a force to the movable joystick 30, controlled by the flight control center 18, and advantageously an auxiliary assembly 46 applying a mechanical force to the movable lever 30, suitable for operating in the event of a malfunction of the active system 44.
    Advantageously, the main energy management system 32 also includes a mechanical stop system 48 which can be overcome.
    The support 40 is suitable for being placed in the cockpit of the aircraft 10, preferably between the seats of the cockpit, in the central pylon.
    As illustrated in FIG. 2, the support 40 comprises a perforated base 50, and an upper cover 52 mounted on the base 50, through which the movable lever 30 is engaged.
    The base 50 defines an interior volume 54, through which a lower part of the movable lever 30 is inserted.
    The upper cover 52 closes the base 50 upwards. Here it has an upper surface 56 curved upwards. It defines a longitudinal slide 58 for guiding the movement of the movable lever 30.
    The mobile lever 30 is a centralized control lever which is capable of controlling a variation of mechanical energy of the aircraft 10, without individually controlling a particular engine 14 of the aircraft 10. The position of the mobile lever 30 in the slide 58 measured by the position sensor 42 is transmitted to the flight control center 18 to generate a command acting jointly on several engines 14 of the aircraft and / or on the energy modification members 16.
    With reference to FIG. 2, the movable lever 30 comprises a rod 60 engaged through the slide 58, a head 62 mounted at the upper end of the rod 60 to be gripped by the hand of a user of the device 12, and a sector 64, integral with the lower end of the rod 60, in the interior volume 54.
    In this example, the movable lever 30 also comprises sliding shutters 66 for closing the slide 58, to prevent the passage of objects through the slide 58 towards the interior volume 54.
    In the example shown in FIG. 2, the rod 60 has at its lower end a horizontal sleeve 68 receiving a horizontal axis 70 of rotation of the movable lever 30, perpendicular to the longitudinal axis A-A 'of the slide 58.
    The head 62 protrudes forward at the upper end of the rod 60. It defines an upper surface 71 for supporting the palm of the user's hand and a lower surface 72 for gripping by the fingers of the 'user. It is here provided with buttons 74 for controlling, for example controlling the airbrakes, or the flight mode.
    The sector 64 is mounted on the lower end of the rod 60, around the axis 70.
    It extends in a plane perpendicular to the axis 70.
    As will be seen below, it is capable of cooperating mechanically with the auxiliary assembly 46 for applying mechanical force, in the event of failure of the active application system 44.
    The socket 68 has a radial finger 74 projecting transversely relative to the axis 70 to cooperate with the active system 44 for applying a force to the movable lever 30.
    The movable lever 30 is thus movable in rotation about the axis 70 in the slide 58 between an extreme rear position and an extreme front position.
    The position sensor 42 is capable of determining information relating to the angular position of the movable lever 30 around the axis 70, and of transmitting this signal to the flight control center 18.
    The active force application system 44 includes an actuator 80, and a mechanism 82 for transmitting movement between the actuator 80 and the movable lever 30. It includes a unit 84 for controlling the actuator 80, visible on FIG. 1, connected to the flight control unit 18, for controlling the force applied to the movable lever 30 and the movement of the movable lever 30 in the slide 58.
    The actuator 80 here comprises an electric motor 86, provided with an output shaft 88 rotatable around a motor axis B-B.
    The motor 86 is preferably a brushless motor. It is electrically connected to the control unit 84 of the actuator 80 which controls the rotation of the shaft 88 in one direction or the other around the axis B-B ’
    With reference to FIGS. 1 and 2, the transmission mechanism 82 advantageously comprises a reduction gear 90, mounted at the outlet of the shaft 88, a finger 92 rotating jointly with the outlet of the reduction gear 90 around the axis B-B ', and a transmission rod 94, interposed between the rotary finger 92 and the radial finger 74 of the sector 64 of the movable lever 30.
    The connecting rod 94 has a first end 96 hinged upstream on the rotary finger 92, and a second end 98 hinged downstream on the radial finger 74. It is capable of transforming and transmitting the rotational movement generated by the motor 80 on the 'shaft 88 around the axis B-B' in a rotational movement of the movable lever 30 around its axis 70.
    The presence of a transmission mechanism 82 provided with a connecting rod 94 guarantees a very flexible movement and without mechanical play of the movable lever 30. Furthermore, the positioning of the motor 86 relative to the lever 30 is freer than in a system comprising gears, which optimizes the space available for positioning the device 12.
    The control unit 84 of the actuator 80 is suitable for receiving in real time the commands produced by the module 28 for controlling the position of the movable lever 30, and for transcribing these commands into a movement of the movable lever 30 in slide 58.
    In particular, the control unit 84 is capable of controlling the actuator 80 to generate a movement force of the movable lever 30 between its extreme rear and extreme front positions, following the calculated position of mobile neutral, in the absence of action of the user on the movable lever 30. This force is a function in particular of the position of the movable lever 30 in the slide 58.
    The control unit 84 is furthermore capable of creating a force applied to the mobile joystick 30 when the user grasps the mobile joystick 30 and moves it around its axis 70 to manually control the variation of mechanical energy of the aircraft. 10.
    The applied force controlled by the control unit 84 depends on the position of the movable lever 30 between its extreme rear position and its extreme front position. It also depends on the evolution context of the aircraft 10, and on the variation of energy available in the aircraft 10, as calculated by the module 26.
    In particular, the control unit 84 is capable of generating profiles of variable force during the movement of the movable lever 30 around its axis 70. Examples of variable profiles as a function of the angular position P of the movable lever 30 are shown in Figures 9 to 11.
    In the example of FIG. 9, the variable profile comprises a ramp 100, the applied force having an increasing intensity when the movable lever 30 moves to its extreme front position.
    In the example of FIG. 10, the variable profile comprises a stable notch 102 around a given position P1 between the extreme rear position and the extreme front position. Once tilted in the stable notch 102, the movable lever 30 is able to remain in this position, since the user must overcome a wall forwards or backwards to leave this position.
    In the example of FIG. 11, the variable profile comprises an unstable notch 104, at position P1, in which the user must overcome a wall to pass position P1, without being able to remain stably in this position.
    The control unit 84 is able to adapt at any time the force profile generated on the movable lever 30, for example the intensity of the ramps 100, and / or the position, the intensity / height, and / or the nature notches 102, 104 as a function of the commands received from the flight control center 18, and the position of the mobile joystick 30.
    In the embodiment of FIG. 1, the control unit 84 comprises a real-time electronic card 106, connected to the flight control center 18, and an electronic engine control unit 108 ("electronic control unit" or "ECU" in English) interposed between the real-time electronic card 106 and the electric motor 86.
    The real-time electronic card 106 comprises for example a processor and a memory, having modules for transcribing the commands received from the central unit 18 into corresponding force profiles to be applied to the movable joystick 30 The electronic engine control unit 108 is capable of generating electrical control pulses, as a function of the raw order received from the card 106.
    It is electrically connected to motor 86 to send the pulses generated to motor 86.
    The auxiliary assembly 46 for applying a mechanical force to the movable lever 30 is intended to remedy a defect in the active system for applying a force 44, for example in the absence of electrical supply to the active system d application of a force 44. It is suitable for switching between a configuration deactivated when the active system for applying a force 44 is active and an active configuration when the active system for applying a force 44 is deactivated .
    With reference to FIGS. 3 and 4, the auxiliary assembly 46 comprises at least one shoe 110 for mechanical cooperation with the movable lever 30, movable between a position engaged on the movable lever 30, in the active configuration of the auxiliary assembly 46 and a disengaged position of the movable lever 30 in the deactivated configuration of the auxiliary assembly 46.
    The auxiliary assembly 46 further comprises a member 112 for resilient biasing of each shoe 110 towards its engaged position, and an actuation system 114 suitable for keeping the shoe 110 in the disengaged position, against the member for elastic stress 112.
    The shoe 110 is mounted movable in translation along an axis parallel to the axis 70 of rotation of the movable lever 30, in a cylinder 113 mounted fixed relative to the support 40, between the engaged position and the disengaged position.
    In its engaged position, the pad 110 is applied on a lateral surface of the sector 64 of the movable lever 30 thus generating a friction force between the pad 110 and the movable lever 30. In its released position, the pad 110 has been moved away from the lateral surface of the sector 64, and no longer cooperates mechanically with the movable lever 30.
    The elastic biasing member 112 is housed in the liner 113 between the liner 113 and the pad 110. It is able to bias by default, the pad 110 towards its engaged position. It is for example formed by a helical spring.
    The actuation system 114 comprises a movable rod 116, and an element 118 for moving and holding the rod 116 in a deployed position. It further comprises a rotary lever 118A and a claw 118B connecting the lever 118A to the shoe 110.
    The lever 118A is pivotally mounted relative to this support 40 about an axis C-C ’perpendicular and not intersecting with the axis 70 of rotation of the movable lever 30.
    The claw 118B is articulated at a first end on the lever 118A. It is received at a second end in a housing of the shoe 110.
    In the presence of an electrical supply of the displacement and holding element 118, the rod 116 in its deployed position is able to cooperate with the lever 118A to maintain the shoe 110 in its disengaged position against the force of elastic bias generated by the elastic biasing member 112, using the claw 118B.
    In the absence of an electrical supply for the displacement and holding element 118, the rod 116 retracts, and no longer cooperates with the lever 118A. The elastic biasing member 112 then deploys the shoe 110 outside the chamber 113 and then presses the shoe 110 against the sector 64 of the movable lever 30.
    The mechanical stop system 48 includes a stop 120 movable jointly with the movable lever 30 and a rocker 121 secured to the support 40 to mechanically cooperate with the stop 120 in an intermediate position of the movable lever 30 between the extreme front position and the extreme position back.
    With reference to FIG. 4, the mechanical stop system 48 further comprises a second mechanical stop (not visible) for passage in a rear sector of the race, and a control 122 for passage of the second stop, visible in FIG. 2 , for example an unlocking pallet mounted mobile on the rod 60 of the handle 30 under the head 62.
    The mechanical stop system 48 is thus able to materialize particular regions for controlling the movable lever 30, between the intermediate position and the rear extreme position of the movable lever 30, for example a zone for controlling the thrust reversers.
    The auxiliary system 34 for individual control of the motors 14 is illustrated by FIGS. 2, 5 and 6.
    As illustrated by these figures, it is mounted adjacent to the main energy management system 32, for example at the rear of the latter, in the longitudinal extension of the support 40.
    The auxiliary control system 34 comprises an auxiliary support 130, and a plurality of levers 132 for individual control of each engine 14. It also includes for each control lever 132, one or more additional sensors 134 for position of the individual control lever 132.
    Advantageously, the auxiliary control system 34 further comprises a cooperation mechanism 136 between the individual control levers 132 (visible in FIG. 6), and an auxiliary mechanical stop system 138 on each individual control throttle 132.
    In this example, the additional support 130 includes, for each individual control handle 132, a slide 140 for moving the handle 132.
    The slides 140 extend parallel to the same longitudinal direction common with that of the slide 58. They are adjacent to each other.
    Each individual lever 132 comprises a rod 142 and a head 144, mounted at an upper end of the rod 142. Each individual lever 132 also advantageously comprises a protective flap 148 closing the slide 140.
    With reference to FIG. 6, the head 144 comprises a central body 150, mounted on the upper end of the rod 142, and longitudinal gripping fingers 152, protruding longitudinally at the front and at the rear of the central body 150.
    The central body 150 projects upwards relative to the finger 152. It defines an axial housing 154 for receiving a light indicator and lateral housings 156 for receiving the cooperation mechanism 136.
    Each finger 152 has a hook-shaped end 158 directed downwards. This end 158 is easily grasped by the finger of a user who inserts himself under the hook 158 either to raise the individual lever 132, or to move it forwards or backwards.
    In this example, the individual lever 132 is rotatably mounted about an axis D-D 'parallel to the axis of rotation 70 of the movable lever 30, between a rear point position in the slide 140, a plurality of intermediate positions in the slide 140, between two stops of the auxiliary stop system 138, and a point position before.
    In the front point position and in the rear point position each individual lever 132 is locked in rotation about its axis D-D ’by a stop.
    Each individual lever 132 is adapted to be moved up along the axis of its rod 142 to pass the stop and reach an intermediate position.
    In the front point position, each individual controller 132 then occupies a rest position, in which the engine 14 associated with the individual controller 132 is controlled by the flight control unit 18 jointly with the other engines 14, on the basis of the position of the movable lever 30, without using the position of the individual lever 132.
    In each of the intermediate positions between the front point position and the rear point position, the engine 14 associated with the individual controller 132 is controlled individually by the flight control unit 18 on the basis of the position of the individual controller 132, without using the position of the movable lever 30. The individual lever 132 can be moved continuously without having to lift it.
    The rear point position advantageously corresponding to the activation of the thrust reversers, or to the shutdown of the engine.
    Each additional position sensor 134 is capable of determining information representative of the angular position of an individual controller 132 associated around the axis D-D ’and of transmitting this signal to the flight control center 18.
    The cooperation mechanism 136 is interposed between each pair of adjacent individual levers 132. It comprises for example a transversely erasable ball and a receptacle for the ball, housed respectively in lateral housings 156 opposite two adjacent heads 144.
    When the ball of the head 144 of a handle 132 is received in the corresponding receptacle of the head 144 of an adjacent handle 132, the handles 132 are movable jointly with one another in rotation about the axis D -D '.
    The ball is capable of disappearing when a shearing force is applied between the adjacent heads 144 of two levers 132. In this case, each of the two individual levers 132 in each intermediate position becomes maneuverable in rotation around its axis D-D ', independently of the other individual lever 132.
    The flight control unit 18 is able to detect that an individual joystick 132 has been moved away from its point position before, to activate the individual control of the engine 14 corresponding to the individual joystick 132 and to regulate the speed of the motor 14, and in particular the thrust, as a function of the angular position of the individual lever 132 in each intermediate position.
    Thus, the auxiliary system 34 for controlling the motors 14 is capable of being activated by a user of the energy management device 12 when the main energy management system fails. It is suitable for allowing the individual control of each engine 14 from a corresponding individual lever 132.
    With reference to FIGS. 7 and 8, the light display system 36 comprises at least one light bar 170, arranged in the vicinity of the centralized control lever 30, and a control unit 172 of each light bar 170, suitable for displaying on the minus a light indication at at least one given point on the light ramp 170. The position of the or each given point is determined by the flight control center 18 and is translated by the control unit 172 into an electrical signal to produce the light indication, as a function of an evolution context of the aircraft 10, in particular as a function of the variation of total mechanical energy of the aircraft 10, calculated at each instant by the flight control center 18.
    In the example shown in FIG. 7, the light display system 36 comprises two parallel light ramps 170, arranged longitudinally on either side of the movable lever 30, parallel to the slide 58.
    Each light ramp 170 extends over at least part of the length of the slide 58, preferably over the entire travel of the centralized control lever 30 in the slide 58 between the extreme front position and the extreme rear position.
    Each light ramp 170 is here formed by a succession of light sources 174 arranged linearly. Each light source 174 is capable of passing from an extinguished state to at least one luminous state, preferably to a plurality of luminous states of different color and / or intensity and / or sequence.
    Advantageously, each light source 174 is formed by a light-emitting diode. Alternatively, the light sources 174 are formed on a screen. Light sources are formed directly on the screen or by backlighting on a strip.
    The ramp 170 defines more than two light sources 174 corresponding to successive positions of the control lever 30 along its travel in the slide 58.
    The control unit 172 of each light ramp 170 is connected to the flight control center 18 via the control unit 84 of the active force application system 44. It is capable of controlling each light source 174 of the light ramp 170 between the extinguished state and the light state or states, as a function of the context of evolution of the aircraft 10, in particular as a function of the variation of available mechanical energy. for aircraft 10.
    Depending on its state, in particular its color, its intensity and / or its ignition sequence, the light source 174 provides a light indication at the point of the light ramp 170 at which it is located.
    Advantageously, the control unit 172 of the light ramp 170 is capable of displaying a first light indication at at least a first point of the light ramp 170 by means of at least a first light source 174 and at least a second light indication, distinct from the first light indication, at at least one second point of the ramp, by means of at least one second light source 174 distinct from the first light source 174.
    The first light indication and the second light indication are of different colors, intensity and / or sequences.
    The control unit 172 of the light ramp 170 is suitable, in a first context of aircraft evolution, for placing a particular light indication at at least one given point on the light ramp 170, at a first source light 174 and in a second context of evolution of the aircraft, placing the same particular light indication at at least one other given point on the light ramp, at a second source 174.
    Preferably, the flight control center 18 is capable of calculating at every instant the position of the given point as a function of the evolution context of the aircraft 10 at this instant and of transmitting this position to the control unit 172.
    Advantageously, the control unit 172 of the light bar 170 is suitable for placing a first light indication on a light section 176 of the light bar 170 formed by a plurality of successive light sources 174.
    The successive light sources 174 of the light section 176 display the same light indication, for example the same color, the same intensity, and / or the same ignition sequence.
    For example, in the context of evolution of the aircraft 10 corresponding to a range of variations in available mechanical energy calculated at each instant, the control unit 172 of the light ramp 170 is capable of displaying a first particular light indication on a light section 176 of the light ramp 170 corresponding to the range of variations in mechanical energy available which can be controlled with the movable lever 30.
    The light section 176 corresponds to the possible movement of the mobile joystick in the particular context of evolution of the aircraft 10, taking into account the variation in mechanical energy available at this time.
    Thus, the pilot has not only information of possibilities of evolution on the basis of the displacement of the position of the movable lever 30 according to the position of movable neutral, but also of a visual indication of the variations of mechanical energy likely to be reached by actuating the movable lever 30, by visual inspection of the light bar 170.
    As illustrated in FIGS. 12 to 14, the control unit 172 of the light ramp 170 is capable of varying the length and the position of the light section 176 as a function of the context in which the aircraft is evolving, and in particular in function of the variation of mechanical energy available for the aircraft 10.
    Thus, the first light indication materialized by the light section 176 in FIG. 12 moves along the light ramp in FIG. 13. The length of the light section 176 varies between FIG. 12 and FIG. 13.
    The first particular light indication has its own color, intensity and / or ignition sequence, for example a green color, constant intensity and a continuous ignition sequence.
    Furthermore, the control unit 172 of the light ramp 170 is capable of displaying a second particular light indication arranged opposite the position of a movement notch of the movable lever 30 in the slide 52.
    The second particular light indication has for example a color, an intensity and / or a sequence distinct from the first light indication.
    For example, the control unit 172 of the light ramp 170 is capable of displaying a second particular light indication at the ends 178 of the light section 176 having the first light indication.
    Advantageously, the position of the second light indication corresponds to that of a notch or a stop generated by the control unit 84. Thus, the pilot has a double tactile and visual indication, corresponding for example to a point particular of the range of mechanical energy variations available for the aircraft 10.
    The control unit 172 of the light bar 170 is advantageously capable of displaying a third particular light indication at a fixed point 180 of the bar, corresponding for example to the position at which the movable lever 30 reaches a mechanical stop of the stop system 48.
    Advantageously, with reference to FIG. 6, the light display system 36 further comprises, for each individual controller 132 corresponding to a motor 14, an additional light source 190, capable of generating a light indicator representative of the operating state. motor 14.
    The light indicator has a first state, for example a first color, when the engine 14 is operational and a second state, for example a second color, when the engine 14 has a malfunction.
    The additional source 190 is here housed in the axial housing 154 present on the head 144 of the lever 132. It is for example formed of a light emitting diode.
    The operation of the energy management device 12 according to the invention will now be described.
    Once the device 12 is activated, after ignition of the engines 14, the auxiliary assembly 46 for applying mechanical force to the centralized control lever 30 is placed in its deactivated position. The rod 116 of the actuation system 114 is deployed and exerts a force on the elastic biasing member 112, spreading the pads 110 of the movable lever 30.
    At each instant, on the ground and during the flight, the calculation module 26 of the flight control unit 18 calculates the current variation of mechanical energy of the aircraft 10 and the range of variation of possible mechanical energy as a function of the thrust available at the level of the engines 14, of the availability of the energy modification members 16, and of the parameters of evolution of the aircraft 10.
    The calculation module 28 of the flight control center 18 then determines the “mobile neutral” position of the mobile controller 30 as a function of the variation in total mechanical energy of the aircraft 10 at each instant, and of the range variation in total mechanical energy capable of being reached by the aircraft 10 at this instant.
    The active system 44 for applying a force to the mobile controller 30 then receives from the flight control center 18, via the control unit 84, a movement instruction from the mobile controller 30.
    The electric motor 86 of the actuator 80 is activated under the effect of the control unit 84 to rotate the output shaft 88 and transmit the movement to the connecting rod 94 via the reduction gear 90 and the rotary finger 92.
    The movement of the connecting rod 94 at its first end 96 is transmitted at its second end 98 to the sector 64 of the movable lever 30 to generate a displacement force of the movable lever 30 which is a function in particular of the position of the movable lever 30 in the slide 58. The movable lever 30 is rotated about its axis 70 to follow the position of the movable neutral.
    The movement of the mobile joystick 30 is therefore controlled by the flight control center 18 in this automatic piloting mode.
    Thus, the position of the movable lever 30 in the slide 58 translates at all times the potential for evolution of the current variation of mechanical energy of the aircraft 10.
    When the pilot wishes to manually modify the mechanical energy of the aircraft 10, he grasps the movable lever 30 and moves it in the slide 58. At each instant, the position sensor 42 determines the angular position of the movable lever 30 around its axis 70. This angular position is transmitted to the flight control center 18 which develops control of the propulsion engines 14 and of the energy modification members 16 as a function of the position of the mobile lever 30 detected by the flight sensor. position 42.
    Furthermore, when the pilot moves the mobile lever 30 away from its mobile neutral position, the active force application system 44 applies a force profile to the mobile lever 30 which is a function in particular of the position of the movable lever 30 in the slide 58. The electric motor 86 is controlled by the control unit 84, to transmit a movement to the reduction gear 90, to the finger, 92 then to the connecting rod 94 and to the sector 64.
    The control unit 84 generates a variable force profile during the movement of the movable lever 30 around its axis 70, for example a ramp 100 having a force having an increasing intensity as a function of at least the position of the movable lever 30 in the slide 58 when the movable lever 30 moves to its extreme front position (see FIG. 9), a stable notch 102 around a given position P1 between the extreme rear position and the extreme front position (see FIG. 10) or / and an unstable notch 104 around the position P1 (see FIG. 11).
    Thus, the pilot is guided at all times in the actuation of the mobile joystick 30, and can intuitively anticipate the operating terminals in terms of energy available on the aircraft 10.
    Once the lever 30 is positioned at the mechanical energy variation setpoint desired by the pilot, a new mobile neutral position corresponding to this mechanical flight energy variation is determined by the control module 28 at all times.
    The pilot can also hold the lever 30 in position against an instruction from the autopilot system which would aim to move it to adjust the position of the moving neutral.
    In the event of a power supply fault in the active system 44 applying force, the actuation system 114 is no longer electrically supplied. The rod 116 retracts and the elastic biasing member 112 brings each shoe 110 back into its engaged position on the movable lever 30.
    Each shoe 110 then exerts a mechanical force on the sector 64 of the mobile controller 30 to maintain the mobile controller 30 in a stable position, in the absence of interaction of the pilot with the mobile controller 30. Furthermore, when the pilot grasps the movable lever 30, the mechanical force exerted by the pads 110 on the movable lever 30 can be overcome, while ensuring precise guidance of the movable lever 30 during its movement in the slide 58. The position information of the movable lever 30 then remains available for the flight control center 18.
    During normal operation of the movable lever 30, the individual levers 132 of the auxiliary energy management system 34 are held in their rest positions, here in their front point positions.
    In the event of an incident preventing the operation of the mobile lever 30, for example in the event of mechanical locking of the mobile lever 30, the pilot lifts each individual lever 132 along its axis and then rotates it backwards to pass the stop . The passage of the stop activates the auxiliary energy management system 34.
    Advantageously, this displacement is obtained by sliding the pilot's fingers under the hook-shaped ends of the fingers 152 of each head 144 of the levers 132.
    Then, the pilot moves each individual lever 132 from its front point position to an intermediate setpoint position.
    By default, the cooperation mechanism 136 between the individual levers 132 is active, so that the individual levers 132 move together with each other. As a variant, when the pilot wishes to pilot each of the engines 14 of the aircraft individually, for example during a failure of one of the engines, he deactivates the cooperation mechanism 136 and individually actuates each lever 132 giving it its own position .
    The auxiliary energy management system 34 is therefore able to compensate for a failure of the main energy management system 32 and to allow the pilot to individually pilot each engine 14 of the aircraft 10. The energy management device 12 therefore provides a redundancy of functions in terms of the propulsion of the aircraft 10.
    Simultaneously, on the basis of an instruction given by the flight control center 18, the control unit 172 of the light ramp 170 places at least one light indication at at least one given point on the light ramp 170 calculated at each instant by the control unit 172 as a function of an evolution context of the aircraft 10, in particular as a function of the total mechanical energy of the aircraft 10.
    Advantageously, the control unit 172 of the light bar 170 places a particular light indication on a light section 176 of the light bar 170 formed by a plurality of successive light sources 174. The successive light sources 174 of the light section 176 preferably display the same light indication, for example the same color, the same intensity, and / or the same ignition sequence.
    As illustrated by FIGS. 12 to 14, in a context of evolution of the aircraft 10 corresponding to a variation of available mechanical energy calculated at each instant, the control unit 172 of the light ramp 170 displays a first light indication particular on a light section 176 of the light ramp 170 corresponding to the range of variations in available mechanical energy which can be controlled with the mobile lever 30.
    The control unit 172 of the light ramp 170 varies the length (see FIG. 14) and the position (see FIG. 13) of the light section 176 as a function of the evolution context of the aircraft 10, and in particular as a function of the variation of mechanical energy available for the aircraft 10.
    The first particular light indication has its own color, intensity and / or ignition sequence, for example a green color, constant intensity and a continuous ignition sequence.
    Furthermore, the control unit 172 of the light ramp 170 displays a second particular light indication opposite the position of a movement notch of the centralized control lever 30 in the slide 52.
    The second particular light indication has a color, an intensity and / or a sequence distinct from the first light indication.
    For example, the control unit 172 of the light ramp 170 displays a second particular light indication at the ends 178 of the light section 176 having the first particular light indication.
    The control unit 172 of the light ramp 170 advantageously displays a third particular light indication at a fixed point 180 of the ramp, for example corresponding to the position at which the movable lever 30 reaches a mechanical stop of the stop system 48.
    Thus, the pilot visualizes at all times the range of movement available to him with the mobile joystick 30, corresponding to the variation in mechanical energy attainable by the aircraft 10, using the first light indication displayed on all the light section 176.
    The pilot also visualizes the limits of movement of the movable lever 30 thanks to the second light indication, displayed at the ends 178 of the light section 176.
    Finally, the pilot advantageously displays the position of a mechanical stop thanks to the third light indication appearing in the fixed position 180 of this stop.
    The length and the position of the light section 176 forming the first light indication, and the position of its ends 178, forming the second light indication is capable of changing over time, as a function of the context of evolution of the aircraft 10, and in particular as a function of the variation in mechanical energy available for the aircraft 10.
    The display system 36 according to the invention is therefore particularly useful for the pilot of the aircraft 10, in his perception of the energy available for the aircraft 10.
    In a particular mode of operation of the device 12, an optimized value of the mechanical energy variation of the aircraft 10 is indicated to the pilot as a function of the evolution phase of the aircraft 10.
    For example, when the aircraft 10 is preparing for takeoff, an optimized value of variation of mechanical energy (corresponding here to an optimal thrust) is determined by the flight control unit 18, in particular as a function of the mass of the aircraft 10 and the length of the runway. A particular light indication is displayed on a point of the light ramp 170 by the control unit 172 opposite the position of the lever 30 corresponding to the optimized mechanical energy variation setpoint. Similarly, the control unit 84 advantageously generates a particular force profile in this position of the lever 30, for example a notch.
    In a variant, the mobile neutral position is not necessarily determined as a function of the variation in mechanical energy available for the aircraft 10.
    In one embodiment, all the motors 14 and the mechanical energy modification members 16 are capable of being piloted jointly by the flight control unit 18 as a function of the position of the movable lever 30.
    As a variant, for a single-engine aircraft 10 or in the event that an engine 14 of the aircraft 10 has been switched off (for example using an individual controller 132), the active engine 14 of the aircraft 10 and the mechanical energy modification members 16 are capable of being piloted jointly by the flight control unit 18 as a function of the position information of the mobile joystick 30.
    In a variant, the energy management device 12 does not have an auxiliary energy management system 34 and / or does not have a display system 36.
