Folding trailing arm landing gear
A folding trailing arm landing gear assembly having a main fitting configured to couple to a hinge positioned at a proximal end; a swing arm rotatably coupled at a proximal end to a distal end of the main fitting; a shock coupled at a distal end to a distal end of the swing arm; a bellcrank coupled at a distal end to a proximal end of the shock, and coupled at a proximal end to the main fitting; and a wheel coupled to the swing arm.
Cable-driven four-bar link leg mechanism
A leg mechanism includes an articulated leg system, a passive device and a cable. The articulated leg system has a leg portion. The passive device is coupled to the articulated leg system and is configured to apply a first force to a portion thereof. The cable is coupled to the articulated leg system and is configured to apply a second force, in opposition to the first force, to a portion thereof. When the cable is drawn away from the articulated leg system, the second force moves the leg portion in a first direction. When tension is released from the cable, the passive device exerts the first force so as to move the leg portion a second direction that is opposite the first direction.

Aircraft landing gear assembly
An aircraft landing gear assembly is disclosed including a landing gear bracket, a fore lever receiving a fore aircraft wheel, an aft lever receiving a rear aircraft wheel, the fore and aft levers being independently moveable, wherein the bracket further comprises a fore lever stop to prevent downwards movement of the fore lever past a lowest rotational position with respect to the bracket at a first angle .sub.1 forward from the notional bracket axis, and a rear lever stop to prevent downwards movement of the rear lever past a lowest rotational position at a second angle .sub.2 behind from the notional bracket axis, wherein the first angle is greater than the second angle. An aircraft and a method of landing an aircraft are also disclosed.

LANDING GEAR
A landing gear (10) includes: a wheel support member (16) including a first portion for rollably supporting a wheel (14), and a second portion extending from the first portion toward a fuselage (12) in a direction of an axis of the first portion and supporting the first portion such that the first portion is rotatable about the axis; a swing support member for supporting the second portion of the wheel support member (16) such that the second portion is swingable relative to the fuselage (12); a retraction actuator (42) for swinging the wheel support member (16) to retract the wheel (14) into the fuselage (12) and deploy the wheel (14) from the fuselage (12); a brace (22) attached to the fuselage (12) and supporting the wheel support member (16); and a joint (20) connecting the brace (22) to the first portion of the wheel support member (16). The joint (20) is disposed closer to the wheel (14) than to the swing support member.
