摘要本文主要研究新型高能燃料用于高能贫氧推进剂的可能性。研究工作包括燃料理论研究,通过论文查找性能数据,设计以 PTFE 作为高能氧化剂,HTPB 作为高能粘结剂的配方,并计算推进剂的放热量和燃烧温度及冲压发动机的力学性能参数,如推力和比冲,准备及筛选材料,设计预处理方法,并在此基础上进行了配方的安全性能与燃烧性能实验。通过配方设计,理论计算,考虑安全因素及药品性价比实际情况,并在试燃烧下筛选材料。结果表明:Be、BeH2、B2H4均有剧毒,可找到的 Al(C2H5)3及 B10H14太昂贵且 Al(C2H5)3储存条件过为苛刻、购买到的NaBH4、AlLi合金、H4AlLi 中NaBH4、H4AlLi活性太强,需要系统研究且 H4AlLi 燃烧残渣过多不适用于推进剂应用。最终得出可用推进剂配方为:Al+Li:PTFE:HTPB=506:494:300。 60305

Title High-energy Poor-Oxegen Pyrotechnic Propellant Formulation Design
Abstract This paper mainly studies the possibility of new high-energy fuel can be used for high-energy fuel-rich propellant. The research work includes fuel theory research, through the relevant papers to find the performance data, design with PTFE as oxidant and HTPB as high energy, high adhesive formulation, and calculate the parameters of mechanical properties of propellant heat and combustion temperature and the ramjet engine, such as thrust and specific impulse, preparation and screening materials, design of pretreatment methods, and on the basis of the experimental formula of safety performance and combustion.Through the design of formula, and the theoretical calculation, considering the actual situation of safety factors and experiment funds, and screening materials in combustion. The results showed that: Be, BeH2, B2H4 are highly toxic, can be found in Al (C2H5) 3 and B10H14 too expensive and Al (C2H5) 3 storage conditions too demanding, to purchase NaBH4, AlLi alloy,H4AlLi,NaBH4, H4AlLi activity is too strong, systematic study and H4AlLi combustion residue need too much discomfort for propellant application. So the last usable propellant formula is: Al+Li:PTFE:HTPB=506:494:300.
