摘要
采用推进剂性能评估软件(PEP)模拟计算,并比较了液氧+HTPB固体燃料、液氢+固体推进剂和液氦+固体推进剂3种固-液混合火箭推进剂方案的能量水平,分析了3种混合推进剂方案的燃烧特征。结果表明,液氢+固体推进剂和液氦+固体推进剂2种混合推进剂方案可大幅提高固体推进剂能量水平,且燃烧性能可能更优。液氢+GAP固体推进剂和液氦+GAP固体推进剂方案可获得高于3 000 N·s/kg的比冲,高于液氧+HTPB固体燃料方案。
The energetic performances of three hybrid propulsion systems including liquid oxygen+curative HTPB fuel,liquid hydrogen+solid propellants and liquid helium+solid propellants were studied by means of propellant performance evaluation program (PEP) .The calculation results reveal that liquid hydrogen+solid propellants and liquid helium+solid propellants may be able to en- hance the energetic performance of almost all the studied solid propellants systems.In particular, the liquid hydrogen+GAP solid pro- pellant and liquid helium+GAP solid propellant hybrid systems can attain specific impulse above 3 000 N · s/kg, higher than that of liquid oxygen+curative HTPB fuel hybrid system.The analysis of combustion process shows that the liquid hydrogen+solid propel- lants and liquid helium+solid propellants may possess better combustion performance than liquid oxygen+curative HTPB fuel hybrid system.
