FIELD: fire fighting equipment with the use of helicopters with rotary propellers, which create powerful descending air flow, particularly to extinguish forest fires.
SUBSTANCE: method involves suspending conical case with fire-extinguishing devices under helicopter and using powerful descending air flow produced by helicopter propellers. If necessary air flow may be mixed with mechanical particles (sand) or chemical additives for extinguishing fires. The case is produced of high-strength and light-weight material to provide case weight of not more than 2 tons.
EFFECT: possibility to use air flow going from helicopter propeller, reduced fuel consumption due to prevention of helicopter usage in shuttle mode, possibility of continuous fire extinguishing, increased helicopter park.
