FIELD: hydraulic engineering.
SUBSTANCE: invention relates to devices for floating objects displacement on water and under water. Water-jet propeller comprises water-jet pipe and propulsor. Water-jet pipe is made of coaxially connected to each other cowling, cylinder, taper adapter and nozzle with discharge valve. On water-jet pipe conical adapter side surface branch pipe with suction valve is installed. Between cowling and cylinder partition with central bore is arranged. Propulsor includes storage battery and solenoid with core fixed on partition installed in cowling, which is connected with piston, which is spring-loaded by bellows arranged in cylinder. One end of bellows is leak-tight connected with partition, and other is with piston. Piston is equipped with head in form of hollow truncated cone with plugged smaller base.
EFFECT: enabling simplified design and reduced noise during water-jet propulsor operation.
