摘　　要：针对飞行器总体快速设计需求,研究了基于支持向量机的气动模型近似方法。通过正交试验设计方法,获取飞行器气动模型的输入输出样本,训练以径向基核函数为基函数的支持向量机,完成飞行器气动模型近似建模。以某飞行器为应用对象开展了实例验证,结果表明该方法能够保证气动模型的精度要求,提高了计算效率,符合总体方案快速设计需求。According to the requirement of rapid design for aircraft, the approximate method of aerody- namic model based on support vector machine is studied. By using orthogonal test design method, the input and output are obtained, the support vector machine based on radial basis kernel function is trained, and the approximate modeling of aircraft aerodynamic model is completed. By taking ple, the results show that the precision requirement of the aerodynamic model can an aircraft be ensured, as an exam- the effwiency of the calculation is improved and the requirements of the rapid design of the overall program are met by ap- plying this method.
