液氧/丙烷推力室试验研究

EXPERIMENTAL INVESTIGATION ON LOX/PROPANE THRUST CHAMBER

1987～1989年间进行的液氧/丙烷推力室试验研究内容主要涉及点火和启动、燃烧、传热等。目的在于探索液氧/丙烷推进剂的技术关键,为新型液氧/烃发动机论证提供必要依据。使用了两种结构状态的推力室。试验室压2.5～7.8MPa。推力8～25kN(真空)。通过试验,考核了液氧/丙烷推进剂的点火和燃烧性能,验证了丙烷再生冷却的可行性;并与四氧化二氮/偏二甲肼自燃推进剂、液氧/煤油推进剂的试验情况进行了比较。

An experimantal investigation on LOX/propane thrust chamber was carried out during 1987-1989.The test mainly involves ignition, start-up, combustion,heat transfer and so on. The purpose of this test is to explore the key technology of LOX/propane propella-nt and to give the necessary evidence for the demonstration of the advanced LOX/hyd rocarbon engine. In this test, two kinds of the thrust chamber were used, the chamber pressure was from 2.5MPa to 7.8MPa and the range of thrust was 8-25KN (vacuum), with the comparison with the test of N2O4/UDMH hypergolic propellant and LOX/ker-osene propellant, the performance of the ignition and combustion of LOX/propane pr-opellant was verified and the feasibility of propane's regenerative cooling was proved
