The propellant feature of burning behavior and engine in hybrid engine, the differences to liquid and solid engine and the difficulties of technology in development were analyzed.
分析了固液发动机推进剂的燃烧特性和发动机性能特性、与液体和固体火箭发动机的不同，以及研制的技术难度等。
When FG and YB are incorporated, they may obviously reduce the pressure exponent of HTPB propellant as well as enhancing the burning rate.
当FG与亚铬酸铜组合使用时，可在提高推进剂燃速的同时大幅度地降低燃速压强指数。
The greater the contents of AP and magnesium are, the higher burning rates of the propellant and the broader flammability limit.
增加AP含量和金属添加剂中镁粉含量均有助于提高推进剂的燃速和拓宽其低压可燃极限。
