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 landing gear assembly for a vehicle, such as a helicopter, includes a linkage coupled to the vehicle and configured to reciprocate between a stowed position and a deployed position. A shock strut forms a part of the linkage. The landing gear assembly further includes a side brace having a first end coupled to the linkage and a second end coupled to the vehicle. The side brace provides a driving force that reciprocates the linkage between the stowed and deployed position. The side brace includes an energy attenuation system that dissipates energy when a compressive load on the side brace exceeds a predetermined threshold.
