    DETAILED DESCRIPTION
    Referring now to the Ligures, in which the invention will be described with reference to specific embodiments, without limiting it, it should be understood that the embodiments disclosed only illustrate the invention. which can be concretized in various alternative forms. Various elements of the disclosed embodiments may be associated or omitted to form other embodiments of the invention. The figures are not necessarily scaled; some features may be exaggerated or understated to show the details of particular components. Therefore, specific structural and functional details disclosed herein should not be construed as limiting, but merely as a representative basis for teaching a subject matter expert to use the present invention in a diverse manner.
    Throughout the description, the terms "fix", "fix", "connected", "coupled", "coupling", "mount" or "montage" will be interpreted as describing the fact that a structural element or component is in some way connected to or in contact with another element, either directly or indirectly through at least one intervening structural element, or it is an integral part of the other structural element.
    Referring to Figure 1, an ejection cylinder 10 is illustrated. The ejection jack 10 is operatively connected to a standby wind turbine at a first end. The emergency wind turbine is movable between a stowed position and a deployed position through the ejection cylinder 10. The emergency wind turbine, when in the deployed position, interacts with a moving air flow to provide a power supply, electric or hydraulic, to an airplane. The ejection jack 10 comprises a rocker module 14.
    The ejection cylinder 10 is operatively connected to the rocker module 14. The ejection cylinder 10 is configured to move the emergency wind turbine between the stored position, in which the wind turbine does not interact. with the moving airflow, and the deployed position in which the standby wind turbine interacts with the moving airflow. The rocker module 14 is movable between a locked position and an unlocked position. The rocker module 14, when in the locked position, helps keep the emergency turbine in the retracted position. The rocker module 14, when in the unlocked position, allows the emergency turbine to be either deployed in the airflow or retracted by the ejection cylinder 10 into the fuselage or the body. of the aircraft so that the emergency wind turbine is put in a stowed position.
    The rocker module 14 includes multiple pivot joints or pivot points that are susceptible to friction. The friction of these pivot points may affect the amount of force available to a rocker module component 14. The amount of force available to the pivot module component 14 may be the amount of force available from an actuator or a solenoid associated with the rocker module 14 subjected to a total distance on which the rocker module 14 can travel to lock and / or unlock. To ensure adequate stroke availability and force margin, shims can be applied to the actuator or solenoid associated with the rocker module 14. The calibration process is somewhat iterative and time consuming. Therefore, reducing friction at pivot points can reduce the need for wedges, can increase course availability, can increase force margins, and potentially reduce the size of solenoid actuators associated with the rocker module. 14.
