纳米铝粉在高能固体推进剂中的应用
Application of Nano-aluminum Powder in High Energy Solid Propellant
摘要
Abstract
The substitution of nano-aluminum powder for 3% (mass fraction) conventional sized aluminum powder can obtain a uniform high energy solid propellant. The effect of nano-aluminum powder on the property of security, mechanics,combustion and energy of the propellant was investigated. The results indicated that the propellant containing nano-aluminum has a much closer inner,a similar density,secure property and mechanical performance in comparison with the propellant containing conventional sized aluminum powder. The additive of nano-aluminum in PET binder system can increase the static and dynamic burning rate and decrease the pressure exponent of the propellant. However,it can not improve the energy performance.关键词
