【摘要】 本文将计算单独机翼的非线性离散涡法和集中涡核法以及二者的结合发展应用于鸭式布局机翼的气动特性计算。在集中涡核的计算模型中除了对机翼附涡系和自由尾涡的模拟外，还包括了对机翼前缘涡的自由涡面、集中涡核及涡核卷吸作用的模拟。本文给出了三种不同形状鸭式布局的算例，结果表明，本方法的计算结果与实验结果和其他计算结果吻合得很好或接近。更多还原

【Abstract】 The nonlinear quasi-vortex lattice method the vortex core method and the combination of them aredeveloped to compute the longi-tudinal aerodynamic coefficients and the lifting pressure distributions of canard-wing configurations.The vortex-core model include the simulating of free vortex sheet,concentrated vortex core and its entrainment effects,besides that of bound vortex sheet and free trailing wake The calcu-lated results of three different canard-wing configurations are presented.The results calculated by the present method agree closely with the exper-imental data or other calculated results.更多还原
