摘要： Wheel acceleration systems are disclosed that provide a motive force to at least one wheel of an aircraft, in order to accelerate the aircraft to takeoff speed with the assistance of main engine thrust. The wheel acceleration system includes a pyrotechnic unit configured to generate expanding gases by combusting a propellant, and a rotary propulsion unit pneumatically coupled to the pyrotechnic unit. The rotary propulsion unit includes an impeller configured to be driven by the expanding gases and to deliver torque to the wheel.

摘要： A shock absorber includes a housing and an end wall slidably disposed within the housing. The end wall and the housing cooperate to define at least a portion of a cavity within the housing. The cavity is filled with a fluid, and a piston is slidably disposed within the cavity. Movement of the piston within the cavity compresses the fluid to provide a spring force. The shock absorber further includes a compensator coupled to the end wall. The compensator positions the end wall within the housing to change a volume of the cavity in response to a change in a temperature of a first element of the compensator.

摘要： The invention relates to a method for controlling the torque of a drive device (1) for rotating wheels (2) of an aircraft comprising actuators for selectively driving rotating wheels of the aircraft to ensure its movement on the ground, comprising the step of regulating a torque generated by the drive device according to a torque setpoint (4) issued by the pilot. According to the invention, the method involves the step of generating, as long as the torque setpoint is not sufficient to guarantee a stable movement speed of the aircraft, a replacement torque setpoint (5) to allow the aircraft to move at a stable speed, and substituting the replacement torque setpoint for the torque setpoint generated by the pilot.

摘要： An aircraft wheel rim includes a main portion and a removable portion. The main portion includes a hub and a disk extending between the hub and an annular outer portion that receives a tire and is shaped to form a rim one of its sides of the annular outer portion. A second side of the annular outer portion is shaped to receive the removable portion, which forms a second flange on the second side of the annular outer portion after a tire has been put into place. The rim further includes a blocking device that limits rotation of the removable portion relative to the main portion. The blocking element include at least one key having a head engaged in a matching receptacle in the removable portion and a root engaging a steel peg that is shrink fitted in the main portion.

摘要： Hydraulic valves for dampening pressure spikes and associated methods are disclosed herein. In one embodiment, a hydraulic valve for dampening pressure spikes includes: a spool configured to move axially inside the hydraulic valve; and a sleeve configured to at least partially house the spool. A location of the spool with respect to the sleeve may determine a flow of a working fluid through the hydraulic valve. A viscous damper is at least partially housed inside an opening in the spool, and a viscous friction between the viscous damper and the opening in the spool slows a motion of the spool.

摘要： An aircraft assembly having: a first part; a second part, the second part being movably mounted with respect to the first part; an electro-hydraulic actuator coupled between the second part and a first anchor point, the actuator comprising a cylinder defining a bore and a piston and rod assembly slidably mounted within the bore and an active chamber within which an increase in fluid pressure causes the actuator to change during a first phase between first and second extension states to move the second part relative to the first part. The electro-hydraulic actuator further includes a hydraulic fluid supply circuit comprising a piezo-electric pump operable to supply pressurised fluid to the active chamber to change the actuator between first and second extension states.

摘要： A system for measuring parameters of a mounted assembly comprises an electronic device for measuring parameters of the mounted assembly and a bonding interface made of elastomeric material surrounding the electronic device. The measuring electronic device comprises: a UHF radiofrequency antenna; and an electronic board with an electronic chip coupled to the UHF radiofrequency antenna, a sensor for measuring parameters of the mounted assembly, a microcontroller and an electrical circuit. The measuring system comprises a ground plane connected to the electronic board. The electronic board comprises an energy manager and a capacitive element. The coupling between the electronic chip and the UHF radiofrequency antenna is of an electrical nature. The electronic chip, the microcontroller and the measuring sensor are components of low energy consumption.
