摘　　要：通过燃气发生器法测试含硼富燃料推进剂一次燃烧喷射效率,分析推进剂组分和喷射装置对一次燃烧喷射效率的影响。研究认为推进剂组分调整中,有利于提高推进剂燃速和一次燃烧温度的因素,基本上有利于提高一次燃烧喷射效率;当硼含量为30%时,通过调整推进剂配方,选用非壅塞喷射装置,一次燃烧喷射效率可达97%。Influences of composition of propellant and ejection device on ejection efficiency of primary combustion of boron-based fuel-rich propellant were studied by measuring the ejection efficiency in a gas generator. The results in regulation of propellant composition indicate that the ejection efficiency can be improved along with the increase of burning rate and combustion temperature. The ejection efficiency can reach 97% by using an unchoked gas generator and suitable composition of propellant with the boron content of 30%.
