FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely, to high-speed semi-submerged vessels or to high-speed submarines equipped with hybrid propulsors acting directly on water. Hybrid underwater propulsion unit for a semi-submersible vessel or submarine includes a streamlined longitudinal hull, one or more underwater electric hydrostriking (EHS) based on Yutkin effect propulsors in the form of streamlined wings-pylons in the form of biconvex symmetric locally articulated spherical, cylindrical or conical surfaces of rotation or in the form of a biconvex symmetrical lens of a lenticular profile with variable curvature with sets of pairs of electrode-dischargers arranged on working surfaces of underwater propellers, working surfaces of the underwater propulsor, on which high and ultrahigh pressures are formed by means of pulsed electric discharge, positive discharge electrodes are made in the form of isolated rods with bare tips, and negative electrode-dischargers are made in the form of circular or polygonal plates isolated from external streamlined shell of underwater EHS-propulsor, power plant for creation of pulse voltages between electrodes-dischargers, water intake devices, one or more water-jet power plant, system of channels-pipelines connecting water intake devices with outlet nozzles. Expulsion of reactive water jets from surface outlet nozzles from power jet system is directed along external surface of hull of semi-submersible ship or submarine in direction opposite direction of vehicle movement. Semi-submersible vessel or submarine is equipped with one or more sustainer water-jet propellers interlocked with EHS-propulsors on wing-pylons in such a way that flowing water flow from discharge nozzles of sustainer water-jet unit flows over working surfaces of EGE-propulsor.
EFFECT: achieving smooth growth of driving forces with minimization of hydrodynamic resistance of moving ship and, as a result, increase in ship speed.
