Abstract
An insensitive pellet ignitor utilizes a slapper type detonator to initiate an insensitive explosive material. The insensitive explosive material is retained in a high strength housing which confines and dissipates the explosion. The insensitive explosive material is retained in a collar placed in a chamber having an orifice leading to propellant. The orifice does not allow the shockwave from the insensitive explosive to prematurely expel the propellant so that the propellant is ignited from the hot gases and particles resulting from the explosion which are ported through the orifice to the propellant.
