A landing gear includes a fixing mechanism, a driving mechanism disposed on the fixing mechanism, a translating member connected to the driving mechanism and configured to move relative to the fix mechanism whey being driven by the driving mechanism, and two supporting feet disposed opposite to each other. The two supporting feet are pivotally connected to the fixing mechanism and movably connected at two ends of the translating member. The driving mechanism is configured to drive the two supporting feet through the translating member to rotate relative to the fixing mechanism.

A rod end of an actuator assembly is disclosed. The rod end may comprise a rod piston end having an outer profile, and a rod joint end opposite the rod piston end, wherein the outer profile comprises an elliptical shape comprising a major diameter and a minor diameter, wherein the major diameter may be larger than the minor diameter in length.

A landing gear arrangement may comprise a shock strut, a retraction actuator, and a shrink actuator. The retraction actuator may move the shock strut between a stowed position and a deployed position. The shrink actuator may move between a shrink position and an unshrink position in response to the shock strut moving between the stowed position and the deployed position.

A magnetic measurement target is configured to be positioned inside a vehicle axle and to cooperate with at least two magnetic movement sensors to measure deformation of the axle. The magnetic measurement target includes a body with a fastener end for fastening to one end of the axle and a main portion. The main portion includes a slot formed in an axial direction to separate two longitudinal portions of the body. Each longitudinal portion of the body presents a target surface for which movement can be measured by a magnetic movement sensor.
