摘要:
为研究消融等离子体及其射流在点火和增强火药的燃烧效应时对电热发射内弹道过程的影响,通过实验得到了毛细管内消融等离子体及其射流压力随时间的变化规律,并对脉冲等离子体射流产生的推力进行了初步测试,采用推力计算公式结合等离子体射流的动力学参数对射流的推力进行了计算。实验结果表明:毛细管内消融等离子体及其射流的压力幅值取决于放电能量,射流的压力相对毛细管内等离子体的压力有一定的滞后,并且耗散得更快;脉冲射流产生的推力具有冲击震荡效应,其最大值和射流压力基本同步;利用推力计算公式得到的推力和实验结果具有一致性。
Abstract:
To investigate the influences of ablation plasma and jet to the interior ballistics of electrothermal propulsion in the ignition and augment of propellant combustion,the pressure-time profiles of plasma and jet are studied experimentally,and the thrust-time profiles are tested primarily.The thrust of plasma jet is calculated by the thrust equations and the parameters of jets.The experimental results indicate that the pressure amplitudes of plasma and the jets depend on the power of pulse power system.There are time delay between the pressure of plasma and jets,and the later dissipates more quickly than the former.The measured thrusts oscillate for a relative long time,and the peak values of thrusts are synchronous with the pressure of jets.The calculation results of thrust agree with the experimental ones.
