  • Patent number: 4828204
    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.

  • Patent number: 4598886
    Abstract: An aircraft intended to fly at supersonic Mach mnumbers is disclosed. The aircraft utilizes a double parasol wing arrangement, with a power plant nacelle located under the wing on each side of the fuselage. Each nacelle is located at the focus of a reflection parabola formed by the undersurface of each wing. In flight the shock wave pressure field created by the nacelles is reflected and redirected by the parabolic wing surface and thereby transformed into beneficial lift. The separation distance between each wing and its respective nacelle is arranged to maximize multiple reflections to thereby further enhance the lift created.
