Abstract
The unsteady numerical method of prescribed motion, which can get all the aerodynamic parameters of any time, was proposed to solve the problems for complex shape aircraft on various lfight conditions. The pitch dynamic derivative of BFM winged missile under 0º~80º initial angle of attack using AVICFD-X software, to comifer the feasibility of the method. The simulation results were in good agreement with the experimental data, which illustrate the nonlinear characteristics of lfow ifeld at large attack angle. Unsteady numerical simulation method implemented in our numerical study considered engineering requirements and obtained good results. Thus, this method is applicable for aerodynamic derivatives on complex shapes.关键词
