高性能高可靠氢氧发动机方案探讨

摘要

According to future requirement of engine for the next-generation launch vehicle, a new derivative LOX/LH2 rocket engine is brought forward based on 50-ton-thrust Oxygen/Hydrogen engine aiming at enhancing performance, function and reliability. The derivative engine utilizes a gas generator cycle or expander bleed cycle with high performance, which can significantly lift capability of the vehicle and realise configuration optimization.%根据未来运载器对动力装置的任务需求及氢氧发动机技术发展趋势，基于50吨级氢氧发动机，以产品性能提高、功能拓展和可靠性增长为设计目标，开展了发动机衍生产品优化设计研究。衍生型发动机基于现有燃气发生器循环或开式膨胀循环，充分继承和借鉴了现有产品的技术基础和成熟组件，产品功能有所拓展，产品性能和可靠性有所提高，丰富了中国氢氧发动机产品库，有利于未来运载火箭构型优化和运载能力提升。
