| 摘 要： | 本文利用超声速线化理论给出的矩形翼载荷系数解析解作为权函数,对沉浮和俯仰谐振的二维平板翼压强系数进行加权修正,获得矩形翼谐振气动力的近似解,计算结果与线化理论数值结果符合得很好,本方法是超声速和高超声速矩形翼非定常气动力的一种统一和快速的计算方法。

| Abstract: | In this paper, the approximate analysis solutions of aerodynamic coefficients are given, which belong to plunging and pitching oscillating supersonic rectangular wings. The solutions are that the frequency perturbation solutions of two dimensional unsteady Euler equations for oscillating supersonic flat plate combine with the loading coefficien analysis solution of the steady supersonic linearized theory for the retanguler wings. Numerical results are presented which confirm the accuracy and very high efficiency of the method. Present method is a efficent computation method of unified supersonic and hypersonic unsteady aerodynamic forces for rectangular wings. |
