Study on Electrical Ignition Characteristics of HAN-Based Liquid Propellant Spray

Abstract:

In order to study the electrical ignition method of liquid propellant spray, two experimental devices of liquid propellant spray and alternating current (AC) pulse discharge were designed. By using of high speed digital camera system, the test on electrical ignition of HAN-based liquid propellant LP1846 spray were carried out under different injection pressures. The results show that under 50W AC pulse discharge conditions, LP1846 droplet cluster, with the mean diameter in the range of 20~40μm, can be ignited reliably. Based on above experiments, a simplified model of ignition delay time of LP1846 single droplet was set up, the calculation value is well matched with the experimental data.
