摘要： A ship which is driven by inboard engines with propellers (3) and by water jets (1) producing jets of water (7). The inboard engines (2) are embodied in the form of electric motors and the water jets (1) are used underneath the bottom of the ship. The electric inboard engines are accommodated in skegs (10) on the underside of the ship. A flow channel is formed between the skegs (10) for the jets of water (7) emitted by the water jets (1).

摘要： The invention relates to the shipbuilding industry and can be used for high-speed vessels, crafts and motorboats. The aim of the invention is to develop a compact water-jet propulsion engine having a reduced weight and reduced dimensional characteristics. Said invention also makes it possible to increase the efficiency of the propulsion engine, improve the productibility thereof and to solve ecological problems. The aim is achieved by reducing the size of a nozzle provided with a slotted outlet section and by using a water-lubricated restraint plate and bearings. The inventive water-jet propulsion and steering system comprises a flow conduit, a hydraulic pressure device provided with a hub fairing and arranged on a shaft with bearings, a straightening device having profiled posts for fixing the hub fairing of a working wheel to the nozzle and a reverse steering device provided with a rotatable deflector. Said water-jet propulsion and steering system enables a vessel to move at different speeds while running ahead, while the vessel is reversed and in a "stop" position, and also to manoeuvre during all modes of motion. According to a model test, said invention makes it possible to increase the propulsion characteristics of the water-jet propulsion and steering system by 5-10 %, the overall dimensions of the reverse steering unit being reduced by 50-60 % and the weight of the water-jet engine by 10-20 %.

摘要： A tunnel jet propulsion unit (11) for marine craft, wherein the passing water mass in the tunnel is converged by decreasing the cross-sectional flow area of the tunnel. The unit (11) comprises an intake section (1); an impeller section comprising a cylindrical housing (31), a rotatable hub (34) and a plurality of radially spaced impeller blades (36); a diffuser section comprising an inwardly tapered inside surface (39), a fixed hub (38) and a plurality of radially spaced diffuser blades (40); a discharge section (D); a bearing between the hubs (34) and (38); and means for rotating the rotatable hub (34). Additional features include an anti-balling by-pass valve (172) positioned upstream from the impeller (33) to relieve excessive water pressure on the hull if unit (11) handling capacity is exceeded and a trim adjusting mechanism in the discharge section (D) for adjusting the height of the unit outlet (30) with respect to the water surface. Also a nozzle (21) having a variable outlet orifice can be used to fine tune performance.
