| 摘 要： | 给出了一种快速计算火箭发动机喷流流场的方法，并在此基础上发展了一种计算喷流与物面间干扰流场及飞行器气动特性的工程计算方法。该方法不仅考虑了喷流与物面的碰撞，还考虑了有攻角下自由来流与喷流间的相互干扰。计算结果表明，该方法对飞行器初步设计是十分有用的工具

| Abstract: | A quick calculation method for evaluation of the exhaust plumes of the rocket motors, and the effects of the exhaust plumes on the flow field around the rocket are considered. In this model, the impingement between the plumes and the surface is calculated with the Newton's theory, furthermore the disturbance between the free flow and the plumes is also considered. The results show that the method is useful for the design of spacecraft. |
