Abstract
A landing gear assembly for an aircraft includes an energy absorber and a land-contact assembly attached to the energy absorber. A retraction assembly is attached to the energy absorber via a pivot point. A trigger assembly is coupled to the energy absorber and the retraction assembly. The trigger assembly is configured to retract the land-contact assembly from an extended position to retracted position in response to a piston of the energy absorber reaching a maximum stroke position in which the trigger assembly triggers an actuator to actuate from a locked position to an unlocked position to release the retraction assembly in a controlled manner which rotates the energy absorber and the land-contact assembly to the retracted position. The maximum stroke position of the piston is beyond normal-operation stroke positions of the piston. A landing gear system and a method of activating the landing gear system utilizes the trigger assembly.
