STEAM-AIR DUCTED-JET ROTARY-AIR INJECTION ENGINE OF INTERNAL COMBUSTION Russian patent published in 2018 - IPC F02B53/08 F01C11/00 F02B47/02 

FIELD: engine building.

SUBSTANCE: invention relates to propulsion engineering. Essence of the invention lies in the fact that the steam-air ducted-jet rotary air injection engine of internal combustion contains a screw air injection unit with a separator, a two-circuit ducted-jet combustion chamber, a twin-rotor screw actuator, a condenser and a variator connecting the screw unit to the actuating motor. In the outlet channel of the air injection unit there is a non-return valve, and an air-water mixture is used as the working fluid, one part of which is separated from the water by a separator and used as an oxidant for burning fuel in the internal circuit of the combustion chamber, and the other part, bypassing the separator, is directed to the second circuit of the combustion chamber, and cooling the outer side of the inner circuit, mixed with the products of combustion of the fuel mixture and enters the working volume of the executive motor with an increased degree of expansion, in which, expanding to ambient pressure, cooled and converted into useful work. Then, passing through the condensation unit, it is divided into water and spent gas mixture.

EFFECT: technical result is increased efficiency at any mode of operation.
