FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, particularly, to propulsors. Device of propulsor for high-speed ship consists of engine, in which fuel is combusted, channel, discharge of combustion products under bottom of ship and slit in ship bottom, which directs combustion products (gases) back in direction of ship. Gases obtained during fuel combustion expand and exit under excess pressure into the slit under the ship bottom backwards, and reactive force of the outgoing gases moves the ship forward.
EFFECT: higher ship speed at high efficiency of power plant.
