  • 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.
