Naval vessel engine

Abstract

The invention provides a naval vessel engine. The naval vessel engine comprises an outer shell which axially penetrates a cavity and a motor, the outer shell comprises a suction guide pipe, a fluid compression section and a power injection section which are sequentially arranged in the axial direction from front to back. The motor serves as a power source, first-stage fluid compression is carriedout on the inflow section, the impeller passing through the fluid compression section and the motor work in cooperation to carry out second-stage high-power compression, and finally pressure is released at the front end of the position of the nozzle after three-stage hole shrinkage compression is carried out on the power injection section, and then fluid is injected out through the injection opening. Furthermore, the whole engine is an independent system, the energy transmission loss is smaller, the maneuverability and flexibility of the ship are higher, and the service life of the mechanism is long.

Description

technical field [0001] The present invention relates to the technical field of ship power, in particular to a ship engine. Background technique [0002] The propulsion device used by ships now transmits the energy generated by the steam turbine to the main shaft through the gear reduction box, and the main shaft drives the propeller to rotate (such as figure 1 shown), generate thrust on the ship to achieve the purpose of making the ship move forward or backward. The position of the propeller is generally below the stern of the ship, and its main weaknesses are as follows: [0003] 1 The efficiency of propeller propulsion is low. too much energy loss; [0004] 2 The position is fixed when the ship is designed for the hull, and the point of application of the force cannot be adjusted; [0005] 3 The mechanical transmission loses part of the energy; [0006] 4. The mechanical transmission produces a lot of noise; [0007] 5 propeller propulsion, to ship shape. into a sha...
