FIELD: engines and pumps.
SUBSTANCE: solid-propellant rocket engine includes housing with channel charge of all-round burning, which is arranged in it, film-type igniter, explosive cartridge installed in front cover of engine, and membrane distributor. Film-type igniter is installed between explosive cartridge and membrane distributor, and in membrane distributor there made are peripheral holes oriented in the gap between engine housing and external surface of the charge. Film-type igniter is tightly fixed by means of adhesive composition on the basis of thermoplastic elastomer and indene coumarone resin to membrane distributor. Along explosive cartridge in membrane distributor there is central throttle hole the diameter of which is 0.3…0.5 of diameter of directed flame jet of combustion products of explosive cartridge.
EFFECT: invention allows improving ignition reliability of solid propellant charge.
