FIELD: fire-fighting equipment, particularly aerosol generation devices. ^ SUBSTANCE: aerosol generator creating gas-aerosol fire inhibiting substance during combustion of cartridges with pyrotechnic compositions and delivering the substance into closed space to be protected comprises body composed of two plate-like containers facing each other. Containers are connected by screwed pins and hold pyrotechnic cartridges contained inside gypsum cement layers. Container rims define disc-like outlet nozzle in which foam plastic packing is arranged. Foam plastic packing end is enclosed with sealant. Ignition initiator formed as resistor covered with adhesive ignition composition electrically linked with trigger is placed in gap between pyrotechnic cartridges in axial symmetry thereto. Plate-like containers serve as end caps. Cylindrical case with diameter equal to container rim diameter is installed between containers and form two disc-like nozzles. Additional pyrotechnic cartridge is placed in the cylindrical case and has gauging bushes for end cap fastening pins inserting. Bushes are formed along coaxial gypsum cement layer periphery. Ignition initiators are installed in gaps between three pyrotechnic cartridges and linked in parallel with common trigger. ^ EFFECT: increased intensity of fire-extinguishing substance delivery, possibility of pyrotechnical charge mass regulation, extended capabilities of closed space protection, increased structural rigidity and operational reliability. ^ 1 dwg |
