FIELD: mechanical engineering. SUBSTANCE: water-jet plant has water-jet propeller 1 and compound two-stroke engine 2 located under water-jet propeller with intake opening upward. Shaft of engine is located in parallel with axis of water-jet propeller 1 towards stern. Water-jet propeller 1 has housing-water conduit 2, straightener 5 in whose hub 10 shaft of rotor 7 is rotatably arranged. Shaft of rotor 7 is fitted in nozzle 13 with recesses over outer surface. Engine 2 is provided with turbine mounted rotatably on output shaft for engagement with it. Shaft holds drive pulley 20 with recesses over circumference; it is kinematically linked with driven nozzle 13 on rotor 7. EFFECT: simple in construction, easy in operation and repair, low noise, ecologically pure, high efficiency. 1 dwg |
