Stability analysis on variable thrust engine of partially catalyzed hydrogen peroxide

Apartially 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.
