FIELD: shipbuilding.
SUBSTANCE: according to proposed method outside water is heated to temperature not exceeding saturation temperature of outside water at pressure, working medium, thus obtained, is accelerated to supersonic speed and then is mixed with cold outside water and discharged in form of reaction jet. Prior to reaching supersonic speed, mixture of working medium and cold outside water is discharge simultaneously in several flows into space with pressure lower than pressure of outside water. Device for implementing the method contains heater, accelerating nozzle for heated working medium, confusor mixing chamber connected with nozzle and at least one channel to discharge mixture of working medium and outside water connected check valve with mixing chamber. Accelerating nozzle is made with contour of supersonic nozzle for water heated to temperature not exceeding saturation temperature at pressure of outside water. Mixing chamber is provided with channels to let in cold outside water and outlet nozzle for flowing out reaction jet.
EFFECT: provision of speed of reaction jet equal to or near sound velocity at device outlet.
