FIELD: transport.
SUBSTANCE: in the first version the helicopter includes a rotor, waterspray nozzles hydraulically connected to a reservoir with the aforesaid fluid through a pipeline, a section of which is laid through the rotor head inside, and a water-pressure device providing water supply to the nozzles, to which the reservoir is hydraulically connected. It is hydraulically connected to longitudinal channels formed in the rotor blades and interconnected with the nozzles via the pipeline, aforesaid section of which is hydraulically connected to the static part of the sealing device. Blade channels are hydraulically connected together with the head to the other rotating part of this sealing device mounted in axial alignment with the head. The water-pressure device may be manufactured either in the form of a compressed-air cylinder connected to the reservoir, manually or remotely using the pipeline valve, or in the form of a pump, through which the reservoir is hydraulically connected with the blade channels. In the second version the helicopter can be connected to a ground- or water-moving power plant, which is connected to the helicopter. The connection between the helicopter and power unit is made in the form of hydraulic pipeline. The reservoir is hydraulically connected to a pump used as the water-pressure device, which is hydraulically connected to longitudinal channels formed in the rotor blades and interconnected with the nozzles via the pipeline laid through the head of the pipeline section hydraulically connected to the static part of the sealing device. The blade channels are hydraulically connected together with the head to the other rotating part of this sealing device mounted in axial alignment with the head. The reservoir and the pump are mounted on the unit.
EFFECT: improved performance of the helicopter with water-jet units.
