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方法。该超声速双翼中的下翼翼型为等腰三角形,上翼翼型为矩形。本发明通过斜激波关系式和Prandtl‑Meyer膨胀波关系式确定了本发明的翼翼型前缘顶点与上翼下表面之间的垂直距离h,下翼翼型的上翼面顶点与上翼翼型下翼面之间的垂直距离h,下翼翼型前缘顶点到上翼下表面的垂足与上翼翼型的前缘点的距离x,以及上翼翼型前缘点到上翼翼型后缘点的距离L,有效缩短设计所述超声速双翼的时间,提高了效率。
