摘要
对国内外含硼富燃料推进剂燃烧性能的研究状况进行了综述,总结了提高含硼富燃料推进剂一次喷射效率和二次燃烧性能所采取的技术途径,主要包括硼粒子的表面包覆、推进剂配方的调整、燃气发生器喷管结构的改进、空燃比的变化、合理燃气喷射方式的选择、进气方式、二次进气间距以及进气量的优化等,这些改进可使含硼富燃料推进剂一次喷射效率提高,燃烧残渣减少,二次燃烧效率也大幅度改善。
The recent development of researches on combustion characteristics of boron-based fuel-rich propellants has been reviewed. The paper summarizes the technical means of adjusting the primary and secondary combustion performance, which include the coating of boron, the adjustment of the formula of propellant, the improvement of the gas nozzle, the quantitative change of air and gas,the appropriate selection of spray regime, the optimization of air inlet mode and the distance between two air inlet, and so on. These efficient measures improve the combustion efficiency of boron-based propellants and reduce the ignition residue.
