SUBSTANCE: invention relates to firefighting equipment and may be used for fire extinguishing in areas located far from water reservoirs. Proposed helicopter comprises compressor with compressed air receiver connected via air gate with air hose made from fireproof material. Vessel made from fireproof material containing fire extinguishing substance is arranged on air hose end. Said vessel is provided with U-pipe and air nozzle communicated with vessel via remote-control pulse valve. Valve is controlled by operator from helicopter cabin. Said valve allows creating repeated shot-time blast exhaust of compressed air with portions of dispersed fire extinguishing substance injected therein.
