【Abstract】 The nonlinear vortex lattice method was applied to com-pute the characteristics of tactical missile aerodynamics at high angles ofattack.The difficulty of convergence and stability on numerical solutionwas overcome by improving the iterative method on solution and the the-ory model of separated vortices and adopting a series of numerical skills.The separated vortices and nonlinear aerodynamic characteristics of com-bination including the body-tail,wing-body-tail and“××”configurationwith vortices shed from body and all kind of vortices shed from lift sur-faces were successfully simulated,so that the adaptabililty and flexibilityof nonlinear vortex lattice method were enhanced in the aerodynamic en-gineering practice.更多还原
