| Abstract: | 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. |
