Supersonic double wings and design method thereof

The invention discloses supersonic double wings and a design method thereof. The wing shape of a lower wing in the supersonic double wings is an isosceles triangle, and the wing shape of an upper wingis a rectangle. According to the method, a vertical distance h1 between the vertex of a wing-shaped front edge and a lower surface of the upper wing, a vertical distance h2 between the vertex of an upper wing surface of a lower wing profile and a lower wing surface of the upper wing profile, a distance x between a vertical foot from the vertex of a front edge of the lower wing profile to a lowersurface of the upper wing and a front edge point of the upper wing profile and a distance L from the front edge point of the upper wing profile to the rear edge point of the upper wing profile are determined through an oblique shock wave relational expression and a Prandtl-Meyer expansion wave relational expression to effectively shorten the time for designing the supersonic double wings and improve efficiency. 一种超声速双翼及其设计
