随着时代的前进,航天事业的发展,火箭发动机这一昔日只有少数人问津的尖端科学技术,今日已开始走出自己神秘的殿堂,逐渐进入科普知识的行列。液体火箭发动机作为火箭发动机技术中最重要的一个分支,无论是在航天领域内或是在导弹武器领域内,都有最广泛的应用,特别是在航天领域内。传热和热防护技术的重要性 液体火箭发动机中产生推力的推力室主要由喷注器、燃烧室和喷管组成。从喷注器喷入的推进剂在燃烧室内燃烧后由 With the advancing of the times and the development of the aerospace industry, the rocket engine, the cutting-edge science and technology that only a handful of people were interested in in the past, has today started to walk out of its own mysterious palace and gradually enter the ranks of popular science knowledge. As the most important branch of rocket engine technology, liquid rocket engines have the most extensive application in the field of spaceflight or in the field of missile weapons, especially in the field of spaceflight. The Importance of Heat Transfer and Thermal Protection Technologies Thrust chambers that produce thrust in liquid rocket engines consist primarily of injectors, combustion chambers and nozzles. The propellant injected from the injector is burned in the combustion chamber
