Abstract
The disclosed invention provides a main landing gear (12, 14, 16, 18) for a high speed (supersonic) aircraft (10) which may be wing-stowed and -mounted in a relatively thin wing (22, 24). The main landing gear (12, 14, 16, 18) is characterized by an inboard gear (12, 14) including a post (58) having a transverse trunnion (52) at a first end (56 or 54) operably mounted on the wing (22, 24). The trunnion (52) is journalled for rotation about an axis for movement of the post (58) between operative and stowed positions. This axis is substantially transverse to the body of the aircraft for forward rotation of the inboard gear (12, 14). A wheel assembly (78, 80) is operably attached at a second end of the post (58). The wheel assembly (78, 80) has a plane of rotation which when stowed in the wing (22, 24) is substantially vertical. In combination with the inboard gear (12, 14) is an outboard gear (16, 18) which includes a post (90) having a skewed trunnion (92) at a first end operably mounted on the wing (22, 24). The trunnion (92) is journalled for rotation about an axis for movement of the post (90) between operative and stowed positions. This axis is skewed relative to the body for obliquely forward and inboard retraction of the outboard gear (16, 18). A wheel assembly (118, 120) is attached at a second end of the post, having a plane of rotation which, when stowed in the wing (22, 24), is substantially horizontal.
