Abstract

We present the results of an analysis of flows in a gap between the reentry vehicle of a manned spacecraft and the propulsion bay located behind it in the case of their separation due to an emergency situation of the rocket in the active region of its trajectory. Emphasis is placed on different-in-nature oscillation processes occurring in transonic flight regimes. An approach to the estimation of the regimes of self-oscillation existence and their frequencies is proposed on the basis of the problem geometry and the flow conditions.

再入飞行器与载人航天器推进舱之间在紧急分离情况下发生的自振荡过程研究

摘要我们介绍了载人航天器再入飞行器与位于其后方的推进舱之间的间隙中的流动分析结果，这种流动是由于火箭在其飞行轨迹的有效区域内出现紧急情况而导致两者分离时产生的。重点是在跨音速飞行状态下发生的不同性质的振荡过程。根据问题的几何形状和流动条件，提出了估计自振存在的情况及其频率的方法。
