Integrated high-speed aircraft, such as high-speed transport aircraft, and associated methods of manufacture. In one embodiment, a high-speed transport aircraft includes a fuselage having a first fuselage portion and a second fuselage portion positioned aft of the first fuselage portion. The first fuselage portion can have a first cross-sectional area and the second fuselage portion can have a second cross-sectional area that is less than the first cross-sectional area. The high-speed transport aircraft can further include a wing and a propulsion system. The wing can extend outwardly from the fuselage at least proximate to the second fuselage portion and can include a leading edge region and a trailing edge region. The propulsion system can include an engine nacelle fixedly attached to the wing and laterally aligned with the second fuselage portion. In one aspect of this embodiment, the engine nacelle can include an air inlet positioned aft of the leading edge region of the wing and an exhaust gas outlet positioned aft of the trailing edge region of the wing.

Integrated high-speed aircraft and associated methods of manufacture

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.
