Non-self-deflagrating fuel compositions for high regression rate hybrid rocket motor application

摘要

Hybrid rocket motor fuel grain compositions with high regression rates (0.05 to 0.15 ips) are obtained in which conventional oxidizers are used at relatively low oxidizer mass fluxes. The compositions include an energetic polymer, preferably a polymer of glycidyl azide in a matrix of inert polymer such as polybutadiene. A preferred composition comprises glycidyl azide polymer (24%), hydroxy terminated polybutadiene (56%) and metallic Al (20%). The composition is cured with an isocyanate.
