Cartridge tightly closing tail compartment inner chamber in initial position is arranged between sustainer SPRE nozzle and tail compartment. Said cartridge can axially move on adapter arranged on sustainer SPRE nozzle edge and is locked on aforesaid adapter by cams or balls. Said cartridge stays in contact with said cams and balls along inclined surfaces located nearby the face of annular clearance 14. On the side of sustainer SPRE nozzle edge, said cartridge passes into smaller-diametre cylinder to form a ledge on inner and outer surfaces. On both cylindrical surfaces of cartridge outer ledge, there is annular clearance with L-like section to get in contact with cartridge to form breech chamber communicated with pyrocartridges 16. Adapter outer surface features similar ledge. Cylindrical sections of adapter outer surface stay in contact with the cartridge to form a cartridge chamber communicated with said breech chamber. Thrust elements in contact with tail compartment face are arranged nearby cartridge face that stays in contact with tail compartment.
