超声速机翼－尾翼组合体的非定常气动力边界元法

本文以Ｇｒｅｅｎ函数为基础的边界元，应用时间历程法，计算机翼－尾翼组合体的非定常气动性能。这为飞行器的设计及其非定常气动特性分析提供了一种有效和完善的计算方法。本文介绍的方法，特别适用于研究、分析各类飞行器非定常动态响应过程的数值计算，例如飞机对突风动态响应等。本文提供的三维机翼的超声速启动过程非定常气动力数值结果，与Ｌｏｍａｘ理论解作了比较，可以看到吻合得很好，说明本文所使用的方法是可行的。对于机翼－尾翼组合体的数值结果，则进一步提供了尾翼受到机翼的洗流影响过程。

A Boundary Element Method of Supersonic Unsteady Aerodynamics for Wing-Tajl Combination

The boundarv element method based on Green theorem is presented in this paper for the computation of supersonic unsteady aero-dynamic forces of wing-tail combinations.It supplies an effective and versatile tool for designing of vehicles and analyzing of their aerody- namic performance,particularly is suitable to numerical calculation for sttidying and analyzing of unsteady response process of various vehicle,such as aircraft response to gust.The numerical data of supersonic tran-sient unsteady aerodynamic forces of three dimensional wing are com-pared with Lomax'S theoritical solution from which it can be seen that the coincidence between them is very well and that this method is ef-fective and versatile,The influence of wing wash process on the tail is also shown for wing-tail combinations.
