目前和今后使用火箭发动机进行轨道和姿态控制的空间飞行器都要遇到发动机排气羽流影响问题.本文讨论了一种迅速估算轴对称的羽流远流场对飞行器影响的近似分析方法和相应的计算机程序.这种点源分析方法考虑了排气气体和喷管的特性.通过计算发动机排气羽流场,计算排气羽流干扰力矩和推力损失,这些影响在飞行器设计中必须给予考虑和控制.利用该方法和计算机程序对一个卫星模型进行了羽流影响的计算.
Current and future spacecraft using orbital and attitude control of rocket engines all have to face the issue of engine exhaust plume influence.In this paper, an approximate method to estimate the influence of axisymmetric plume far field on aircraft is discussed and the corresponding The point source analysis method takes into account the characteristics of the exhaust gas and the nozzle The exhaust plume interference torque and thrust loss are calculated by calculating the exhaust plume field of the engine and these effects must be considered in the aircraft design And control.Using this method and computer program to calculate the plume influence on a satellite model.
