摘要：

The combustion characteristics of NEPE propellants were studied in detail by measuring flame structure, combustion waves and SEM, et al. It was showed that pressure exponent of NEPE propellant had a inflection point at high pressure. The model of combustion process of NEPE propellant is transferred from nitramine-CMDB propellant type to AP-CM-DB propellant type with the increase of combustion pressure and the content of AP. The content of nitrate ester group, and the diffusion progress of AP monopropellant flame in gas-phase were significant manipulative factors in controlling the inherent burning rate and pressure exponent of NEPE propellants.
