ABSTRACT:
Disclosed is a steerable, articulated landing gear particularly useful on cargo aircraft and providing a capability to selectively raise and lower the aircraft fuselage, and hence the cargo deck, to a height convenient for loading and unloading of cargo therefrom. The gear includes a shock strut, and a wheel lever on one end of which are mounted two wheels. The wheel lever is pivotably connected to the lower end of the strut at an articulation point remote from the rotational axes of the truck wheels. An extendable-retractable shock absorber mounted within the strut is connected to the lever at a point between the strut-lever articulation and the rotational axes of the wheels. Retraction of the shock absorber lowers the strut-lever articulation relative to the axes of the wheels. A ground-engaging member or "kneeler" depending downwardly from the lower end of the strut at the strut-lever articulation defines a flat, horizontally orientable, ground engaging surface. When the truck wheels are contacting the ground, lowering the strut-lever articulation causes the flat surface on the kneeler to engage the ground and the kneeler to assume at least part of the load borne by the gear. In one embodiment, the strut is extendable and retractable independently of the shock absorber and in another the effective height of the kneeler is adjustable.
