【Abstract】 The internal damage in NEPE(Nitrate Ester Plasticized Polyether) propellants caused by the action of detonation waves and its effect on propellant combustion are investigated experimentally.The damage characteristics are inspected by scanning electronic microscope observation on propellant samples.Thermal analysis tests for the samples show that the damage is helpful for the thermal decomposition of nitrate(NG/BTTN) in NEPE propellants,and the closed-bomb test shows that the burning rate is accelerated considerably by the internal damage in the propellants.更多还原
