Two types of conventional igniters were characterized for use in a 30-mm regenerative injection liquid propellant gun. The characterization consisted of performing a series of tests in which the igniters were vented into a closed chamber. Pressure-time characteristics and the degree of repeatability were determined for the igniters. Both types of igniters are based on the use of a M52A3B1 M52 electrical primer coupled to a booster charge consisting of either a solid propellant charge of IMR 4350 for one type of igniter, or a liquid propellant charge of LGP 1846 for the second type of igniter. Two designs were examined for the type with the solid propellant booster charge. The first design consisted of discharging the M52 into a bed of IMR 4350 rifle powder, part of which was constrained in a plastic soda straw.
