【Abstract】 The combustion wave temperature profiles and the flame structures of NEPE propellant samples are measured by using W Re micro thermalcouple and flame photo techmique. The influence of major component of propellant (such as HMX,AP,Al)on the combustion properties is researched; Meanuhile the surface appearance and element distribution of extinguished samples are analyzed by JMS 5800 SEM. The combustion process of NEPE propellant is suggested by synthetic analysis.更多还原
