Electric ignition and stable combustion of hydroxylamine nitrate-based liquid propellant for different components
To avoid the shortcomings of long delay time and catalyst deactivation of traditional catalytic ignition for hydroxylamine nitrate(HAN)-based liquid propellant,and give full play to the advantages of high energy density and high specific impulse of HAN-based liquid propellant.The experimental systems of electric ignition for static and flowing state of HAN-based liquid propellants were designed and constructed.Four new kinds of high-energy HAN-based liquid propellants were prepared.The electric ignition and stable combustion experiments of propellants for static and flow state were studied.The effects of different components on the ignition and stable combustion of HAN-based liquid propellants were compared.The addition of methanol inhibited the activity of the propellant.Meanwhile,the decomposition process of the propellant became slow and no stable combustion flame was observed.The propellant mixed with 15％acetonitrile showed excellent performance in flame height and ignition delay time,and it could maintain the flame combustion by self-decomposition after closing the voltage for the flow state.
