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.
