SENSITIVITY PROPERTIES AND BURNING RATE CHARACTERISTICS OF HIGH ENERGY DENSITY MATERIALS AND THE PROPELLANTS CONTAINING THESE MATERIALS
SINOPSIS
Recently many kinds of high energy density materials (HEDM) have been developed. Among these materials are glycidyl azide polymer (GAP) as a binder for propellant, and ammonium dinitramide (ADN) and hydrazinium nitroformate (HNF) as oxidizer. Thermal decomposition tests, impact sensitivity tests, and friction sensitivity tests were conducted for GAP, ADN and HNF. The impact sensitivity and the friction sensitivity of HNF are higher than those of ADN. The burning rates of GAP propellents were measured. The burning rates of GAP/Ammonium Perchlorate (AP) propellants are well explained by the Granular Diffusion Flame Theory. As the concentration of AP is increased, the diffusion process becomes slower and chemical reaction process in the gas phase becomes faster. As the particle diameter is decreased, the diffusion process becomes faster. The burning rates of GAP/ADS propellants were also measured.
