| 摘 要： | 针对带有进气道导弹的气动力估算方法不能满足概念设计阶段对气动力计算的要求问题,建立一种适用于带有进气道导弹的法向力估算方法和程序。以细长体理论和部件组合法为基础,引入进气道与弹身间的气动干扰因子修正系数和弹身-进气道组合体与弹翼（尾翼）间的气动干扰因子修正系数,以实例对带有进气道的导弹法向力系数进行估算,并与计算流体动力学（CFD）计算结果进行比较。估算结果与CFD计算结果符合较好,最大误差小于5%,可用于导弹的概念设计和初步设计阶段。

| Abstract: | An approach for predicting normal aerodynamic force coefficient of missiles with inlets was developed and evaluated aimed at the problem that the existing aerodynamic estimation method for missiles with inlets can not meet the requirement of aerodynamic estimation in conceptual design.By taking inlet as a wing with tiny aspect ratio,and introducing correction coefficient of the interference factor between body and inlet and correction coefficient of the interference factor between body-inlet assembly and wi... |
