An apparatus for igniting a gas generating propellant grain which is susceptible to shattering when suddenly exposed to pressure above a predetermined pressure. The apparatus comprises a housing having a peripheral side surface, an axial end surface and a longitudinal central axis. An ignitable material is contained in the housing. The ignitable material develops hot gases, flame and pressure within said housing upon combustion of the ignitable material. The peripheral side surface of the housing ruptures at a pressure which is substantially less than the predetermined pressure at which the propellant grain shatters to direct the hot gases and flame radially of the longitudinal central axis of the housing to ignite the propellant grain.

An apparatus for igniting a gas generating propellant grain which shatters when suddenly exposed to pressure above a shattering level greater than approximately 1500 psi, said apparatus comprising: a housing having a longitudinal axis, a closed axial end wall, and a closed peripheral side wall; an ignitable material contained in said housing, said ignitable material developing hot gases, flame and pressure within said housing upon combustion of said ignitable material; and means for containing said hot gases, said flame and said pressure within said housing until said pressure reaches a rupturing level equal to approximately 750-800 psi, and for permitting said side wall of said housing to rupture when said pressure reaches said rupturing level to direct said hot gases and said flame radially out of said housing through said side wall to ignite said propellant grain.
