ABSTRACT:
A twin-engine supersonic airplane having an arrow-shaped wing and an elongated fuselage extending approximately equally forward and rearward of the wing. The fuselage is configured for six passengers in a staggered two-abreast seating arrangement and for two pilots seated in tandem. A forebody section of the fuselage, which extends substantially forward of the wing, is of a specific geometric cross-sectional design, i.e., it is an egg-shaped cross section with opposite sidewalls sloping vertically inward in an upward direction. The sidewalls are only of a single curvature in a fore-and-aft direction, and this substantially flat surface has windows installed therein which have an optically flat surface in order that a minimum of visual distortion is produced due to thermal expansion during supersonic flight. Twin vertical stabilizers are spaced apart and each is mounted near a wing tip; and the stabilizers extend both vertically above and below the wing chord plane for functioning as wing tip end plates. Outboard of the vertical stabilizers is an auxiliary wing in coplanar alignment with the main wing and rotatably movable as a unit for lateral roll control and/or longitudinal pitch control of the airplane. The twin engines are spaced apart on either side of the fuselage, between the fuselage and the vertical stabilizers, and mounted to the undersurface of the wing.
