摘　　要：50吨级氢氧发动机是中国为新一代运载火箭研制的首台大推力氢氧发动机。该发动机充分借鉴了中国以往的氢氧发动机研制经验,采用数字化设计手段、极具特点的研制模式以及新材料新工艺技术,突破了一系列关键技术,具有较高的可靠性和性能水平,可大幅提升中国进入空间和利用空间的能力。The 50 t class Oxygen/Hydrogen engine is the first large-thrust Hydrogen/Oxygen engine in China for new generation launch vehicle. The engine is based on China＇s cryogenic engine development legacy and makes use of the technical experiences acquired through prior engines. Furthermore, a wide array of numerical analysis and design tools are implemented, which progressing the development project and shortening the development time. Being the first large cryogenic LOX/LH2 engine in China, the 50 t class Oxygen/Hydrogen engine program is a key element of China accessing and using space in future, and it gives the potential to perform a broad array of missions.
