摘要:
为避免硝酸羟胺(HAN)基液体推进剂传统催化点火的延迟时间长、催化剂失活等缺点,同时充分发挥HAN基液体推进剂高能量密度、高比冲等优点,设计并搭建了HAN基液体推进剂静置状态和流动状态下电点火实验系统。制备了4种新型高能HAN基液体推进剂,并开展了静置状态和流动状态下电点火及稳定燃烧实验研究,对比了不同组份下HAN基液体推进剂点火及稳定燃烧的影响。甲醇的添加抑制了推进剂的活性,推进剂分解过程变得缓慢且没有观察到持续稳定燃烧的火焰。掺混15%乙腈的推进剂在火焰高度和点火延迟时间等方面都表现出优异性能,流动状态下在关闭加载电压后能通过自分解维持火焰的燃烧。
Abstract:
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.
