摘要
为研究煤基高能煤油的点火及燃烧性能,开展了气氧煤油姿控发动机热试车,研究了煤基高能煤油发动机真空比冲性能、脉冲工作性能和响应特性。结果显示:煤基高能煤油发动机点火可靠、燃烧稳定,脉冲工作性能和启动/关机响应特性均满足工程应用要求,真空比冲性能相比火箭煤油基础油发动机提高了约7s。
Firing-tests of attitude control engine for GOX/kerosene were carried out to study the iginition and combustion characteristics of coal-based high energy kerosene. The vacuum specific impulse,pulse operation performance,response performance of coal-based high energy kerosene engine were studied. Results show that the engine has reliable ignition and stable combustion performance by using the coal-based high energy kerosene. The pulse operation performance,starting and shut off response performance could satisfy the engineering application requirements. The vacuum specific impulse is 7s higher than that of the basic rocket kerosene engine.
