分别以碳掺杂的乙醇、甘油、单推-3和聚叠氮缩水甘油醚(GAP)为典型的液态工质,在不同能量激光注入的情况下,研究了烧蚀产物及其诱发的工质溅射,获得了推力变化规律。结果表明,溅射初期的高速喷射过程是推力形成的主要阶段。随后的溅射过程使质量流量增大,但对冲量耦合的贡献较小,进而使得整体推进性能下降。
Carbon-doped ethanol, glycerol, monosubstituted-3 and poly-azide glycidyl ether (GAP) were used as typical liquid working fluids. The ablation products and the induced workers Quality sputtering, obtained the thrust variation. The results show that the high velocity jet at the initial stage of sputtering is the main stage of thrust formation. Subsequent sputtering increases the mass flow but contributes less to the impulse coupling, which in turn causes the overall propulsion performance to drop.
