Jet hovercraft includes hull, hull guard, reservoirs for fresh water located in the hull, centrifugal fans to discharge compressed air under hull bottom and create air cushion and gas-steam turbine plants for centrifugal fans operation, jet gas-steam turbine plants placed on deck for vessel movement which plants use water as energy carrier and produce effective power and traction force, installed in vessel hull steam generator working on exhaust hydrogen and oxygen with temperature of 500-550°C and connected by main steampipe with steam header of jet gas-steam turbine plant and refrigerator for cooling exhaust hydrogen and oxygen from steam generator which header is connected to accumulating reservoir and distribution device, steam generator connected to cooling system of jet gas-steam turbine plant working on liquid-metal coolant, connected with steam turbine and with main steampipe, connected to electric generator switched to electric board and to condenser, jet gas-steam turbine plant plasmochemical reactor power supply unit connected to electric board. The jet gas-steam turbine plant includes housing with diffuser for atmospheric air intake with starting motor installed in its cowling, jet nozzle for traction force creation accommodating cone and injectors to inject hydrogen or hydrocarbon fuel to force plant and increase traction force, and two power units installed in the hull and containing thermodissociating gas turbine plant and steam turbine plant connected by shaft from one side with electric generator switched to electric board and from the other side - with high-pressure fan for creation of air movement in ring-shaped channel between the hull and power units and centrifugal compressor connected to combustion chambers equally spaced along circumference for combustion of dissociation products - hydrogen and oxygen - and creation of traction force. The thermodissociating gas turbine plant for producing energy source - hydrogen and oxygen - and useful power is performed with plasmochemical reactors equally spaced along circumference for thermal dissociation of water steam and obtaining hydrogen and oxygen with temperature exceeding 2500°C and with high pressure, connected to power supply, communicating at one end by means of disk-valve with holes for steam intake and ring-shaped labyrinth seals, rotating at specified frequency, with steam header, and at the other end are connected with expanding nozzles and cylinders of wave compressors having injectors for water or liquid metal injection in them connected to gas turbine mounted on shaft connected with electric generator which turbine is provided with outlet pipe to discharge exhaust hydrogen and oxygen into steam generator. The plasmochemical reactors for thermal dissociation of water steam and producing hydrogen and oxygen with temperature exceeding 2500°C, expanding nozzles and cylinders of wave compressors have jackets for cooling liquid circulation - liquid metal cooler and water - for cooling nozzle walls - anodes of plasmochemical reactors. The plasmochemical reactors contain housing with jacket which housing communicates with cooled nozzle - anode, with located in housing at specified distance from its walls electrode-cathode mounted in device being connected to power supply, with located in housing injector for injection of easily-ionising additive, or several plasmochemical reactors with located in housing injector for injection of easily-ionising additive are located in one unit connected with expanding nozzles of wave compressors at one end, and at the other end communicate with disk-valve having holes for steam intake and ring-shaped labyrinth seals, or several plasmochemical reactors located in one unit contain housings with jacket, cover and dome, with electrodes-cathodes mounted in housings at specified distance from their walls in electric insulation layer, which housings communicate with cooled nozzles-anodes. On the unit of plasmochemical reactors, valve mechanism with inlet valve water steam intake. Valve mechanism includes fitting pipe for steam intake which fitting is connected with header attached to housings of plasmochemical reactors, with inlet valve located on header, with limiter and spring for water stem intake. Steam turbine plat for hydrogen combustion in oxygen and obtaining useful power is made with axial compressor connected to distributing device, which compressor is connected in series with connecting cylinders, combustion chambers equally spaced along circumference including injectors for hydrogen ignition in oxygen due to injection of gaseous jets of electroconducting liquid thermal dissociation products and hybrid injectors for injection of gaseous mixture of electroconducting liquid and hydrocarbon fuel thermal dissociation products, with expanding nozzles and cylinders of wave compressors, connected to steam turbine mounted on shaft connected with thermodissociating gas turbine plant and electric generator, which turbine is provided with outlet fitting pipe to discharge exhaust steam into condenser. Axial compressor is made with two housings, with inlet chamber with atmospheric air intake shutter gimbal-mounted on it. The second housing is equipped with inlet fitting pipe for intake of dissociation products - hydrogen and oxygen - from distributing device. Injector for hydrogen ignition in oxygen contains housing with fitting pipes for electroconducting liquid infeed which pipes are connected with cylindrical channels located inside housing in electric insulating material layer. On one end of these pipes, electrodes connected to pulse oscillator are installed, and on the other end nozzles are made which are directed at an angle to each other and communicating with injector explosion chamber having bottom with outlet holes for gas jets. The hybrid injectors contain housing with fitting pipes for electroconducting liquid infeed which pipes are connected with cylindrical channels located inside housing in electric insulating material layer in parallel with fuel injector location. On one end of these pipes, electrodes connected to pulse oscillator are installed, and on the other end nozzles are made which are directed at an angle to each other and communicating with injector explosion chamber having outlet nozzle for gas jets.
