FIELD: jet engines.
SUBSTANCE: inventions group relates to the field of jet engines and jet propulsion for river and/or sea vessels. A detonation pulsating water-jet engine (DPWJE) includes a control unit, a housing, an inlet valve grill for inlet of the oncoming water flow, an explosive gas electrolyzer, the electrode plates of which are installed on insulators parallel to the direction of the oncoming water flow, with the possibility of free exit from the housing through the confuser and outlet nozzle. In the upper part of the inner surface of the housing above the electrode plates of the “explosive gas” electrolyzer, there is a volumetric explosion detonation chamber containing at least one fuel injector of the fuel supply system, at least one injector of the oxidizer supply system and at least one spark plug and/or detonation tube of the ignition system to create an initiating impulse of a volumetric explosion, and the external terminals plus and minus of the "explosive gas" electrolyzer are connected to the extreme electrode plates through bushings. The detonation water cannon (DWC) includes a control unit, a housing of a combined water jet turbine, inside which a shaft is installed on support bearings that can rotate freely and on which at least two impellers of an axial hydraulic turbine are rigidly fixed, between which at least one working wheel is rigidly fixed a wheel with straight blades of an impulse hydraulic turbine that does not interfere with the axial movement of water in both directions. At least two DPWJE are installed on the outer side of the housing of the combined jet turbine.
EFFECT: high ecology is achieved when using "explosive gas" and/or an air-fuel mixture based on inexpensive natural gas in a DPWJE and DWC.
