Electrically controlled and/or actuated landing gear mechanisms are presented that allow for adjustment of aircraft attitude on the ground as well as for retraction and extension of the landing gear in a single unit. Most preferably, the electric actuator is positioned within the diameter of the strut to thereby form a compact and load bearing structure.

What is claimed is: 1. A landing gear assembly for raising and lowering a wheel assembly of an aircraft having an airframe, comprising:a strut and a trailing arm;the strut having (a) a length adjuster that connects to the airframe via a first pivot, and (b) a spring damper that connects to the trailing arm via a second pivot;a motor disposed between the first and second pivots and operable to drive the length adjuster; andthe trailing arm connecting the wheel assembly to the airframe via a third pivot, such that the first, second and third pivots are the only pivots needed to raise and lower the wheel assembly, wherein the trailing arm further comprising a straight portion, the trailing arm having one end connected to the third pivot and a second end farthest from the third pivot being attached to the wheel assembly.
