An airplane airframe having wings connected to the fuselage by spars of smaller cross section than the wings. Movable winglets may be provided at the outboard ends of the wings. The fuselage may be an airfoil shaped lifting body structure with longitudinal splines at its edges. The splines may be movable in flight, and may be provided with flaps which are also movable in flight so that the splines can be readjusted to alter the aerodynamic characteristics of the airframe during flight. The undersurface of the fuselage may include cambers symmetrical abou...
An airplane airframe designed for high subsonic, transonic or supersonic speeds comprising: (a) a fuselage structure; (b) wings, each having a leading edge, a trailing edge, an inboard end and an outboard end and being connected to said fuselage structure at said inboard end; (c) spars intervening between said fuselage structure and said inboard ends of said wings, each such spar having an airfoil configuration, the maximum height of which is substantially less than the maximum height of the wing at or about the inboard end thereof, only one such spar be...
