Abstract
To elucidate the influence mechanism of the mass ratio of ammonium perchlorate(AP)to octogen(HMX)on the combustion performance of nitrate ester plasticized polyether(NEPE)propellants,multiple testing methods including the under-water acoustic emission method,micro-thermocouple technique,coaxial digital holography and condensed-phase product col-lection method were adopted in this study.The effects of AP/HMX mass ratio(13/50-19/44)on the burning rate,combustion wave structure and condensed-phase product characteristics of NEPE propellants were systematically investigated.The results show that with the increase of AP/HMX mass ratio,the burning rate of propellants increases from 11.4 mm·s-1 to 12.3 mm·s-1,the explosion heat rises from 6820 kJ·kg-1 to 7107 kJ·kg-1,the thickness of condensed-phase preheating zone decreases from 317.3 μm to 183.6 μm,the burning surface temperature rises from 336℃to 494℃,the maximum temperature of gas-phase flame zone increases from 2934℃to 3017℃,the median diameter of aluminum agglomerates decreases from 275.86 μm to 209.77 μm,and the active aluminum content in condensed-phase products decreases from 2.55%to 0.86%.The combustion performance of NEPE propellants can be regulated by adjusting the AP/HMX mass ratio via the synergistic action of thermody-namics and kinetics.关键词
