摘要
Abstract
The ignition energy and combustion characteristics of HTPE solid propellants were investigated by CO2 laser ignition and combustion test system.The effects of pressure,atmosphere,initial temperature(-50-70℃)and burning rate regula-tor on the burning rate,flame morphology,combustion temperature and minimum ignition energy of HTPE solid propellants were analyzed.The results show that HTPE solid propellant has lower flame intensity,burning rate,and combustion tempera-ture than hydroxyl-terminated polybutadiene(HTPB)solid propellant.The increase of temperature,pressure and oxygen con-tent can increase the combustion intensity and decrease the minimum ignition energy of HTPE solid propellant.The minimum ig-nition energy of the three HTPE solid propellants(HTPE_0,HTPE_Ca,HTPE_Sr)is0.738,1.038 and 1.862Jat-50℃,re-spectively.The low temperature initial environment can significantly increase the minimum ignition energy.The calcium car-bonate and strontium carbonate can inhibit the burning rate of HTPE solid propellant.关键词
