专利说明:

The invention relates to a device for maneuvering and immobilizing a plane on the ground. Prior to take-off, it is generally necessary to move the aircraft away from the ground facilities so that it can move independently.
According to a first operating mode, this movement maneuver is performed using a motor vehicle that is driven by a first operator and pushes the aircraft away from the facilities (pushback maneuver in English).
The powered vehicle is connected to the aircraft's nose landing gear and the nose landing gear control system is disengaged by the pilot of the aircraft to allow said landing gear to pivot freely in function of the direction imposed by the motorized vehicle. According to a first variant, the motorized vehicle is connected to the landing gear by a bar. According to another variant, the motorized vehicle comprises grippers that lift the wheels of the landing gear.
The first operator who drives the vehicle does not have good visibility on the entire aircraft, a second operator walks next to the vehicle and controls the pushing maneuver.
Therefore, this first procedure is not fully satisfactory because it requires two people on the ground.
According to a second operating mode, the embossing maneuver is carried out using a motor vehicle controlled remotely. According to one embodiment, this motorized vehicle comprises a cockpit for maneuvering and a remote control that allows remote control.
The vehicle comprises two branches which are positioned in operation on either side of a main landing gear, each of the branches comprising two pressure rollers positioned at the front and rear of the wheels to cause the rotation wheels of the landing gear by friction. For each branch, one of the two rollers is movable between a retracted position in which it allows the passage of the landing gear between the two branches and an extended position in which the wheels of the landing gear are locked between the rollers.
According to this second operating mode, an operator drives the motorized vehicle to a main landing gear of the aircraft. After correctly positioning the branches of the vehicle on either side of the landing gear, it controls the deployment of the rollers. Following, he moves away from the vehicle to control the pushing maneuver and guide the pilot of the aircraft. It has a remote control to cause the stop and the rotation of the rollers and thus the movement of the plane.
According to this procedure, according to the instructions transmitted by the operator on the ground, the pilot of the aircraft orients the front landing gear to direct the aircraft. At the end of the pushing maneuver, thanks to the remote control, the operator on the ground can remotely provoke the retraction of the rollers to release the landing gear and the setting in motion of the motorized vehicle in order to move it away from the 'plane.
This motorized and remotely controlled vehicle makes it possible to carry out the pushing maneuver with a single operator on the ground.

This type of sensor makes it possible to determine more precisely the position of the mobile 18 relative to the landing gear. According to one embodiment, the detection sensor is an ultrasound sensor. However, other solutions are possible for the sensor for detecting the position of the landing gear.
Whatever the variant, the mobile 18 comprises a detection system comprising at least one positioning sensor and / or navigation.
Advantageously, the device for maneuvering a plane on the ground comprises at least one base 48 at which the mobile 18 is positioned when it is not in use.

Advantageously, the base 48 is configured to recharge electrical energy mobile 18 immobilized at said base 48. According to one embodiment, the base 48 includes a socket configured to connect to a socket of the mobile 18 to recharge its batteries .
According to one embodiment, the device for maneuvering a plane on the ground comprises at least one software allowing from a first instruction to autonomously and automatically move the mobile 18 of the base 48 to a main landing gear 16 from an airplane and from a second instruction to autonomously and automatically move the mobile 18 of a main landing gear 16 to the base 48. For this purpose, the software analyzes information transmitted by the detection system and transmits information to the controller 44 to control the motor (s) and the actuator (s) of the mobile 18.
In general, the software allows the mobile to move from a first point to a second point autonomously and automatically, including up to a landing gear or from a landing gear.
According to a configuration, the software is implemented in the controller 44.
According to another characteristic of the invention, the mobile 18 comprises an immobilization mechanism for immobilizing it. Thus, it is possible to use the mobile 18 as a wedge. Therefore, an operator can remotely control the mobile 18 so that it moves from its base 48 to a main landing gear 16 and that, when correctly positioned relative to said landing gear, the rollers 42 move in the deployed position. By following, activating the immobilization mechanism of the mobile 18, the wheels of the aircraft blocked by the mobile 18 are thus immobilized on the ground. Thus, the operator in charge of the maneuver does not have to approach the wheels of the aircraft.
According to a first variant, the mobile 18 comprises at least one brake for immobilizing at least one of its wheels 34.1 to 34.3.
According to another variant, the mobile 18 comprises at least one hinge for lowering the frame 20 relative to at least one wheel 34.1 to 34.3 so that the frame 20 is in contact with the ground. Thus, the frame 20 occupies a first position in which it is spaced from the ground and allows the mobile 18 to move and a second position in which it is in contact with the ground and immobilizes the mobile 18. Preferably, the mobile 18 comprises several joints to lower the frame 20 relative to all the wheels. This solution increases the contact area between the frame 20 and the ground in the second position.
Advantageously, the controller 44 can activate or not the immobilization mechanism of the mobile 18 to receive a third instruction.
According to another characteristic of the invention, the control 19 is an apparatus 52 with a touch screen on which graphic elements 54.1 to 54.4 are represented, for example in the form of each of a virtual button (visible in FIG. 6). The device 52 may be a touch pad, a smartphone, etc.
Each of the graphic elements 54.1 to 54.4 is dedicated to an instruction. Thus, a first graphic element 54.1 makes it possible to trigger the movement of the mobile in a first direction, for example to make the aircraft go backwards, a second graphic element 54.2 makes it possible to stop the movement of the mobile 18, a third graphic element 54.3 makes it possible to activate or deactivate the immobilization mechanism on the ground of the mobile 18 and a fourth graphic element 54.4 can trigger the movement of the mobile in a second direction opposite to the first direction, for example to advance the aircraft. At least, the touch screen of the device 52 comprises two graphical elements, a first graphical element 54.1 to trigger the movement of the aircraft in a first direction and a second graphical element 54.2 to control the stop of the displacement of the plane.
The graphic elements 54.1 to 54.4 are arranged at the vertices of a geometrical figure which extends over the entire surface of the touch screen of the apparatus 52. For example, in the presence of four graphical elements 54.1 to 54.4, they are arranged at the vertices of a diamond, a square or a rectangle that occupies the entire surface of the touch screen of the apparatus 52.
Such an arrangement (in number and arrangement) of graphic elements 54.1 to 54.4 distributed over the entire surface of the touch screen of the apparatus 52 simplifies the control of the maneuvering operations of the aircraft on the ground and improves ergonomics of the aircraft maneuvering device on the ground. Thus, the operator in charge of controlling the pushing maneuver remains attentive to the environment of the aircraft which tends to limit the risk of incidents.
According to another characteristic, the same control 19 can control several mobiles 18 and / or the same mobile 18 can be successively controlled by several commands 19. For this purpose, each mobile 18 and each command each include an identifier of its own and which is different from the identifiers of other mobiles and other commands 19.
The coupling of the control and the mobile is achieved via the communication protocol.
According to one embodiment, the apparatus 52 comprises an electronic module making it possible to identify another apparatus operating with the same communication protocol and to select it to obtain a coupling of the control and the mobile. The apparatus 52 may not be dedicated to the spinning maneuver.
Preferably, the apparatus 52 comprises an application that makes it possible to carry out the pushing maneuver.
Advantageously, this application includes a first display for entering an aircraft identifier. This solution makes it possible to be able to determine the position of the main landing gear 16 around which the mobile 18 is to be positioned and thus to determine the trajectory to be followed by the mobile 18 to reach said main landing gear 16.
This first display also comprises at least one graphic element representing a button for triggering the first movement instruction of the mobile 18 of the base 48 to the main landing gear 16 and activation of the coupling mechanism 38 and at least one element graphic representing a button for triggering the second disengagement instruction of the mechanism 38 for coupling and moving the mobile 18 of the main landing gear 16 to the base 48. The application also includes a second display which makes it possible to display the graphic elements 54.1 to 54.4 shown in Figure 6.
According to another characteristic, the device for maneuvering a plane on the ground comprises a second communication system allowing an exchange of information between a ground operator in charge of controlling the operation of the aircraft and a cockpit of the aircraft.
This second communication system comprises a headset with earphones and a microphone carried by the ground operator allowing him to interact with the pilot of the aircraft. This communication system can use different communication protocols such as Wifi, VHF, ...
According to a first embodiment, the headset communicates via a Wifi type communication protocol, Bluetooth with a box connected to an intercom of the aircraft. According to a second embodiment, the headset communicates via a WiFi type of communication protocol, Bluetooth with the controller 44 of the mobile that communicates with the pilot via a VHF type communication.
According to a third embodiment, the headset communicates via a VHF type communication with the pilot of the aircraft.
According to one mode of operation, when an aircraft 10 reaches a parking zone 12, thanks to the command 19, an operator remotely controls the movement of the mobile 18 of the base 48 to the main landing gear 16, the deployment rollers 42 for locking at least one of its wheels and the activation of the immobilization mechanism of said mobile 18. Thus, the mobile 18 performs the wedge function to immobilize the aircraft on the ground. When he wishes to carry out a repoussage operation, an operator deactivates, by means of the control 19, the immobilization mechanism of the mobile 18. By following, he triggers the setting in motion of the airplane in the desired direction by activating the rotation or rollers 40, 42 in the correct direction of rotation, by clicking on the first graphical element 54.1. During the pushing maneuver, the operator guides the pilot through the second communication system and monitors the environment of the aircraft. At any time, the ground operator can stop the pushing maneuver by clicking on the second graphical element 54.2. If necessary it can activate the immobilization mechanism of the mobile 18 in order to immobilize the aircraft on the ground, by clicking on the graphic element 54.3. If the aircraft must return to its starting position the ground operator triggers the setting in motion of the aircraft in the desired direction by activating the rotation of the roller or rollers 40, 42 in the appropriate direction of rotation, in clicking on the graphical element 54.4. During the maneuver of the aircraft on the ground, the pilot controls the orientation of the front landing gear according to the instructions given by the operator on the ground. At the end of the pushing maneuver, the operator can remotely control the retraction of the rollers 42 to release the main landing gear 16 and the movement of the mobile 18 of the main landing gear 16 to the base 48 .
Thus, according to the invention, a single operator on the ground is necessary to perform the embossing maneuver safely.
In addition, the device of the invention makes it possible to prevent an operator on the ground from approaching the wheels of the landing gear. Thus, all the rigging and maneuvering operations on the ground of the aircraft are carried out at a distance from the aircraft.
