部分催化过氧化氢变推力发动机的稳定性分析

Stability analysis on variable thrust engine of partially catalyzed hydrogen peroxide

提出了一种部分催化发动机方案,该发动机在大范围推力调节时能维持压降基本不变;通过与不催化和全催化方案比较,证明该发动机具有更大的稳定工作范围;对该方案发动机的调节性能开展了仿真研究,当采用斜坡输入时,发动机具有快速、稳定的响应特性.

A partially catalyzed engine scheme was presented. This engine could keep the inject pressure drop almost unchanged when the thrust varies very much. It＇s proved that this engine functions stably in a wider thrust range if non-catalyzed engine and fully-catalyzed engine are compared. The regulating performance of this engine was also simulated. The results show that the engine＇s response is rapid and stable when ramp input is employed.
