In one structural arrangement the fire fighting nozzle (18) is connected to the compressor (7) of a gas-turbine engine (4). In the second structural arrangement the fire nozzle (18) is connected to a screw compressor (50) connected to a diesel engine (47). Both types of fire extinguishing equipment have the same fire nozzle (18), whose mixing chamber (19) for the generation of a high-speed two-phase dispersive stream (21) of a bubble structure is made in the form of a block of mixers (35) with front and rear partitions (36,37), in between which pipe mixers (38) are located. Each mixer (38) is equipped with a confusor (43) and a diffusor (44). On the outlet from the fire nozzle (18) the high-speed dispersive stream (21) contains droplets of sizes 100-300 μm. The fire nozzle (18) has a mixing chamber (19), divided by partitions (36, 37) to a water supply chamber (40), air supply chamber (41) and dispersing chamber (39). The dispersing chamber (39) narrows into a gas-dynamic propelling nozzle (20), from which a high-speed dispersive stream (21) comes out. The fire nozzle (18) is connected to a rotating mechanism (22) which rotates it vertically and horizontally. The control unit (2) is equipped with a remote control (34) and connected to an generator (3).

higher lower (7) (7) of adapter (9) of the fire extinguishing equipment has an outlet speed of up to 36 m.s--1and a reach up to 25 m. The high-pressure water pump (2) at 10 000 revolutions per minute, has a displacement on the outlet (26) from the pump (2) of 1 liter of pressurized water per 1 second at the pressure of 2 MPa and power of the electric engine (3) of 3,5 kW and voltage of 60 V. · this pressurized water suctions on a regulated basis the ambient atmospheric air without pressure through the first suction orifices (14) into the mixing chamber (12), in which air and water get mixed into the mixture of a two- phase flow of air and drops of water; • the obtained stream of air and drops of water behind the mixing chamber (12) gets reformed into a two-phase bubble-structured flow of droplets of water and bubbles of air by passing through the indent sections of outlet elements of the firefighting nozzle(1); where · into the outlet adapter (9) outside air is suctioned on a regulated basis through the outlet orifices (24) of the outlet partition (23); and · the generated two-phase flow of a turbulent character and bubble structure of dispersed drops of sizes 10 to 300 pm comes out of the outlet (7) from the firefighting nozzle(1) of the fire extinguishing equipment to the place of fire at the speed of up to 36 m.s-1 and maximum reach up to 25 m.
