Abstract : An igniter for solid fuel rockets in which hot gases from an initiator are channeled to drive a piston against a reservoir of combustion modifying fluid, like ethylene glycol, so as to spray the fluid onto the propellant grain just before ignition. After the piston moves, the hot gases escape the igniter as to ignite the propellant directly or through an intermediate main ignition charge. (KAR) P.1
