Abstract

The invention discloses a cuttlefish-like pulse jet propeller, which belongs to the technical field of ship underwater propulsion. The cuttlefish-like pulse jet propeller mainly comprises a water spraying device, a supporting device and a driving device, wherein the water spraying device comprises a sliding end cover, a guide rail connector, a deformable cavity pipe, a water storage pipe, a nozzle, a water suction one-way valve and a water spraying one-way valve; the supporting device comprises a supporting shell, a supporting arm, a guide rail, a supporting arm end plate, a motor support, a shaft support, a front connecting ring and a rear connecting ring; and the driving device comprises a crankshaft, a connecting rod, a crosshead and a rotating motor. The invention provides a pulsed jet propulsion scheme with high cuttlefish jet propulsion efficiency, low noise and strong anti-cavitation capability, so that the cuttlefish-like pulsed jet propeller realizes the function of periodic jet recoil propulsion.

Description

technical field [0001] The invention belongs to the technical field of ship underwater propulsion, relates to ship water jet propulsion technology, in particular to a squid-like pulse jet propeller. Background technique [0002] The current ship underwater propulsion technology mainly includes propeller propulsion, water jet propulsion, pump jet propulsion and so on. Propeller propulsion technology has a long history and is the most mature, and is widely used in the propulsion of various ships and submarines; however, the disadvantages of propeller propulsion technology are also obvious, such as large underwater radiation noise, and due to the existence of cavitation, the speed of conventional propeller ships has reached critical. Waterjet propulsion technology has developed rapidly since the 1980s. Because of its high propulsion efficiency, low underwater radiation noise, and higher critical speed than conventional propellers, it has great prospects in the propulsion of me...
