LOVA发射药在低装填密度下的点火对于未来具有钝感模块装药的火炮系统是有意义的。传统推进剂系统中的点火系统传统上是针对高装填密度而优化的。需要能够控制系统包封的点火，以减少低装填密度下的未燃推进剂，同时避免高装填密度下的压力波。等离子体点火对于这种应用是有趣的，具有改变点火能量的可能性，并且等离子体羽流深入推进剂床以实现均匀点火。本文介绍了在45毫米火炮系统中，使用NL 008（RDX基CAB-LOVA推进剂）的等离子点火实验结果。等离子体点火器是一种毛细管射流型，由脉冲形成网络驱动。一个零维模型的等离子体点火器已经开发，并将在实验的背景下进行讨论。
The ignition of LOVA gun propellants at low loading densities is of interest for future gun systems with insensitive modular charges. The ignition system in conventional propellant systems is traditionally optimized for high loading densities. There is a need to be able to control the ignition for the envelop of the system, to reduce unburnt propellant at low loading densities and, at the same time, avoid pressure waves at high loading densities. Plasma ignition is interesting for this application, with the possibility to vary ignition energy and with the plasma plume penetrating deep into the propellant bed to achieve uniform ignition. This paper presents results from plasma ignition experiments in a 45-mm gun system, using NL008, an RDX-based CAB-LOVA propellant. The plasma igniter is a capillary jet type, driven by a pulse-forming network. A zero-dimensional model for the plasma igniter has been developed and will be discussed in the context of the experiments.
