Ignition Methods for a 155-mm Regenerative Injection Liquid Propellant Gun
Abstract
Methods are discussed for igniting a 155-mm regenerative liquid propellant gun (RLPG). A discussion is given of the igniter design requirements and the igniter concepts under consideration. The designs differ in the location in which the igniter charge is burned, the type of propellant used as the igniter charge, and the method in which the igniter charge is initiated. The igniter design concepts fall into two categories, external and internal. In an external igniter the igniter charge is burned outside the gun chamber in a precombustion chamber at a high loading density. In an internal igniter, the igniter charge is burned inside the gun combustion chamber at a lower loading density. The propellants investigated for an igniter charge include hydrogen-air mixture, fuel-air mixture, and liquid propellant, the latter being most desirable because it will be stored on the Self Propelled Howitzer (SPH). The ignition source being considered is electrical because of its availability on the SPH.
