液化天然气作为液体火箭发动机的推进剂具有成本低、燃烧时不产生煤烟灰等许多优点,引起广泛关注。其存在问题是液化天然气中含有的微量硫磺成分对发动机有一定硫腐蚀问题,且热分解时的结焦问题会影响发动机性能。针对上述问题进行了大量研究试验,取得大量数据,并介绍了试验方法与结果。 As a propellant of liquid rocket engine, liquefied natural gas has many advantages such as low cost, no soot and the like when burning, and has drawn wide attention. The existing problem is that the trace sulfur components contained in liquefied natural gas have certain sulfur corrosion problems to the engine, and the coking problem during thermal decomposition will affect the engine performance. A large number of research experiments have been conducted on the above problems, a large amount of data have been obtained, and the test methods and results have been introduced.
