FIELD: machine building.SUBSTANCE: solid fuel gas generator comprises a cylindrical body with a feed unit, an insert charge of solid fuel, a detachable cylindrical shell coaxial with a body, installed between a body and a charge, with gaps that communicate between each other. The feed unit is formed with nozzles arranged on a cylindrical part of a body in one radial plane. Ends of the cylindrical shell are connected with front and rear bottoms, accordingly, and communication of gaps is arranged with the help of holes in a cylindrical shell arranged opposite to feed holes on the body. On the front and rear bottoms there are detachable protective screens with overflow holes to form cavities between them and inner surfaces of the bottoms, not communicating with the cavity between the body and the cylindrical shell.EFFECT: invention makes it possible to increase reliability of a gas generator, due to reduction of a thermal effect level to power elements of a body and a reduced level of erosion influence of combustion products at a charge surface.1 dwg |
