Ammonium dinitramide–based energetic ionic liquid propellants (ADN‐EILPs) exhibit the advantages of high energy density, low toxicity, and handling safety, and are therefore promising monopropellants. Herein, we characterized the ignition of ADN‐EILPs induced by CW laser heating in the presence of carbon fibers, clarifying the effect of laser power and suggesting that ignition reproducibility is influenced by the difference of ADN‐EILP osmotic state in carbon fibers or carbon fiber configuration. The observed ignition behavior allowed one to conclude that (i) high‐power CW laser heating causes the formation of bubbles on the surface, which disturbs further heating; and (ii) an Arrhenius‐type relationship exists between ignition delay and heating rate, suggesting that the strategy of foreshortening ADN‐EILP ignition delay by increasing CW laser power has certain limits.

碳纤维对基于二乙酰胺铵的离子液体的连续波激光加热点火的表征

基于二硝酰胺的高能离子液体推进剂(ADN-EILP)具有高能量密度,低毒性和操作安全性的优点,因此是有前途的单推进剂。在此,我们对碳纤维存在下连续激光加热引起的ADN‐EILP着火进行了表征,阐明了激光功率的影响,并暗示着碳纤维或碳纤维中ADN‐EILP渗透态的差异会影响着点火再现性。组态。观察到的着火行为使人们得出以下结论:(i)高功率连续波激光加热会在表面形成气泡,从而干扰进一步的加热;(ii)点火延迟和加热速率之间存在Arrhenius型关系,
