摘　　要：论述了用非线性离散涡法来模拟大迎角下翼－身组合体涡流绕流的计算模型及计算方法；给出了一个典型翼－身组合体的涡流流态计算结果及其非线性气动特性和截面压强（或载荷）分布。Two computed models and a numerical method based on nonlinear discrete vortex method are presented to simulate the vortex flow about wing-body combinations.The two computed models consist of a same fuselage vortex model but a different vortex model for simulating the wing leading-edge vortex indiyidually, one model has a concentrated line vortex/sink and the other has a number of diffused vortex filaments. The vortex flow patterns and the nonlinear aerodynamic characteristics of a typical wing-body combination haye been calculated. Comparing with the experimental data, it is shown that the computational results are resonably accurate.
