Abstract
The landing gear comprises a shock absorber (4) having a rod (6) slidable in a cylinder (6), a wheel (12) linked to the cylinder, a guide sheath (14) surrounding the shock absorber (4), releasably engageable means (17) for fixing the cylinder at least in rotation relative to the guide sheath (14), and a strut (21) surrounding the sheath. When the strut is retracted under the control of an actuator (42) a rod (80) draws the sheath (14) into the strut (21) thereby compacting the landing gear lengthwise, at the same time a helical groove (38) cooperates with a groove follower (40) to turn the sheath, and hence the shock absorber cylinder (6) and the nose wheel (12) so that the wheel lies flat inside the aircraft when retracted.
