过氧化氢推力室技术研究

简述了过氧化氢作为火箭推进剂的优点，重点介绍了近几年陕西动力机械设计研究所在过氧化氢单组元推力室和双组元发动机推力室研制中取得的进展。设计了几种过氧化氢单组元推力室并进行了试验；进行了过氧化氢／煤油双组元火药点火试验；进行了催化点火技术的研究，27次点火试验全部取得成功；设计并生产了几种双组元推力室，对过氧化氢／煤油自燃点火技术进行了研究，累计进行了500余次点火试验；采用37kN推力室分别进行了90％过氧化氢／煤油的火药点火试验和自燃点火试验，试验获得了成功。

A Study of thrust chamber technology using hydrogen peroxide

The research on hydrogen peroxide mono and bipropellant combustion chamber conducted by Shaanxi Power Machine Design and Research Institute (SPMDRI) in recent years is presented in this paper. Several hydrogen peroxide monopropellant thrusters were designed and tested. The powder ignition tests for hydrogen peroxide/kerosene were conducted. The catalytic ignition torch technology was also studied, and all of the 27 firing tests were successful. Several bipropellant chambers were designed and produced, and the hydrogen peroxide/kerosene hypergolic ignition characteristics were studied with 500 firing tests. Powder ignition and hypergolic ignition firing tests of 90% hydrogen peroxide /kerosene were also successfully conducted with 37kN thrusters.
