摘要：A landing gear for an aircraft has a multi-wheeled truck that is swung by a mainprop from a stowed position to a lowered position below the aircraft. The truck ispivotably connected to the lower end of the main prop. When the gear is lowered, atleast one rear prop extends between the upper end of the main prop and an aft regionof the wheel truck. Both the main and rear props are telescoping members. However, therear prop is releasably lockable to hold a certain fixed length when the aircraft is on theground, so as to prevent pivoting movement of the wheel truck relative to the main prop.This impedes the ability of the aircraft to tip back when its center of gravity shifts aftduring unloading.
