摘要： A metering pin for use in a multi-actor damping system is disclosed herein. The multi-actor damping system may be used in a shock strut assembly to alter a damping curve of the shuck strut assembly. The metering pin may be configured to transition the multi-actor damping system from a first damping actor configuration to a second damping actor configuration. The first damping actor configuration may correspond to a first damping curve. The second damping actor configuration may correspond to a second damping curve. The first damping curve being different than the second damping curve.

摘要： An aircraft landing gear is disclosed having a landing gear leg attachable at a first end to an aircraft, and an axle beam, both the landing gear leg and the axle beam being rotatably mounted. The axle beam is rotatable between a first position, in which a first end of the axle beam is a first (shorter) distance from the first end of the landing gear leg, and a second position, in which said first end of the axle beam is a second (longer) distance from the first end of the landing gear leg. A biasing member is configured to be able to bias the axle beam towards the second position. An aircraft, a blended wing body aircraft, and a method of operating an aircraft are also disclosed.

摘要： A shock strut is disclosed herein. The shock strut includes a shock strut cylinder, a shock strut piston slidably disposed within the shock strut cylinder, a rebound chamber disposed within the shock strut cylinder and adjacent the shock strut piston, a first percolation seal configured to restrict a first flow of fluid between the shock strut cylinder and the rebound chamber, and a second percolation seal configured to restrict a second flow of fluid between the shock strut cylinder and the shock strut piston.

摘要： A shock strut is provided that includes a first energy absorption stage or load limiter and a second energy absorption stage or load limiter. The second energy absorption stage or load limiter can include one or more disc springs. The shock strut can be employed on both fixed and retractable landing gear alike, while providing design adjustability for obtaining load-deflection curves that accommodate a range of descent or impact velocities.

摘要： A fuse pin valve includes a housing, a piston, and a mechanical fuse, such as a fuse pin. As assembled, the piston is movably disposed in the housing and is retained in a static position by the fuse pin. Upon a certain pressure (e.g., an abnormal pressure) acting on the piston, the fuse pin fails, thereby releasing the piston to move from a first or start position to second or end position. In the start position of the piston, the valve is in a first operational state (e.g., a closed state). In the end position of the piston, the valve is in a second operational state (e.g., an open state, fully open states, etc.). In other embodiments, in the start position of the piston the valve is in an open state, and in the end position of the piston the valve is in a closed state.

摘要： A method of operating an electromechanical actuator includes coupling an inner portion of a split ball screw with an outer portion of the split ball screw, rotating the split ball screw about an axis to drive a ball nut in a first axial direction, in response to a failure mode of the electromechanical actuator, decoupling the outer portion of the split ball screw from the inner portion of the split ball screw, and translating the outer portion of the split ball screw and the ball nut in a second axial direction.

摘要： A landing gear of an aircraft having an upper portion intended to be joined to a structure of the aircraft and a lower portion provided with a first and second axle, the first axle being provided with a braked wheel and the second axle being provided with a motorised wheel, includes a first actuator that moves one of the axles between remote and close positions with respect to the upper portion while the other axle is kept stationary with respect to the upper portion. In one of the remote and close positions, and the wheels on the axles are simultaneously in contact with a running surface while, in the other position, each wheel on the second axle is at a distance from said running surface.

摘要： A method for monitoring a shock strut may comprise measuring a first shock strut pressure, measuring an ambient temperature, measuring a shock strut stroke, measuring a second shock strut pressure, and determining a servicing condition of the shock strut based upon the first shock strut pressure, the ambient temperature, the shock strut stroke, and the second shock strut pressure, wherein the servicing condition indicates whether it is desirable for the shock strut to be serviced with at least one of a liquid and a gas. The first shock strut pressure and the shock strut stroke may be measured before the takeoff event with a weight of an aircraft supported by the shock strut.

摘要： A system for servicing a shock strut may comprise a system controller and a tangible, non-transitory memory configured to communicate with the system controller. The tangible, non-transitory memory may have instructions stored thereon that, in response to execution by the system controller, cause the system controller to perform operations, which may comprise: receiving, by the system controller, a hydraulic fluid volume difference or a pressurized gas volume difference from a ground support controller; determining, by the system controller, a desired fluid flow rate based on the hydraulic fluid volume difference or the pressurized gas volume difference; and outputting, by the system controller, a desired fluid flow rate signal corresponding to the desired fluid flow rate to at least one of a hydraulic fluid flow controller or a pressurized gas flow controller.
