FIELD: transport.
SUBSTANCE: invention relates to ship building and may be used for various ships. Proposed propulsor comprises pipeline and device to create water jet by forming travelling water waves. Said pipeline is arranged below water-line in symmetry on both sides of ship hull. Holes extending into pipeline made at equal distance L along ship hull. At least, two pairs of displacement piston pumps are located inside the hull on every side. Said pumps are rigidly jointed with ship hull and communicated with said holes via feed hoses to run in reciprocation mode. Extra hoses are arranged between pump cylinders and said holes. Switching solenoid valves are arranged in hoses and extra hoses.
EFFECT: higher efficiency and reliability.
