| Abstract: | This paper summarizes the status of deep throttling rocket engines and LOX/LCH4 rocket engines. A scheme of LOX/LCH4 deep throttling rocket engine is discussed. The power balance and heat transfer are computed based on careful analysis. The results show that the engine can throttle from 100% to 10% in thrust. LOX/LCH4 deep throttling rocket engine could be widely used in variety launch vehicles and spacecrafts, and be helpful to future China Lunar Exploration Program and Manned Lunar Plan and be beneficial to technologies of LOX/LCH4 liquid rocket engines and future Manned Mars. |
