为了使导弹获得最佳性能,本文研究了两种情况.其一,选用一台已有的空气喷气发动机,将导弹总体参数与发动机转速调节方案结合起来优选.算例说明,该方法可用.其二,将导弹外形参数、总体参数与发动机调节方案联合进行优选并在发动机数学模型中充分考虑安装对发动机性能的影响. In order to get the best performance of the missile, this paper studies two situations: First, choose an existing air-jet engine, the overall parameters of the missile combined with the engine speed adjustment program optimization example shows that the method is available. Second, the missile shape parameters, the overall parameters and the engine adjustment program jointly optimized and in the engine mathematical model to fully consider the installation of the engine performance.
