Power plant of water surface ship

Abstract

The invention discloses a power plant of a water surface ship. The power plant comprises a pulse detonation tube and an engine inclined tube body, wherein the engine inclined tube body is divided into an inclined section and an outlet section, and a buckling is arranged between the inclined section and the outlet section; the port of the inclined section of the inclined tube body of an engine is coaxially connected with the outlet of the pulse detonation tube by virtue of a flange, and the tube wall of the inclined section is provided with a pressure probe; a controllable water inlet with a close device is arranged on the tube wall of the inclined section, and a signal processing system and a steering engine are connected between the close device and the pressure probe in series; the projected area of the outlet section of the controllable water inlet on the transverse section is at least 50% of that of the outlet section port; and when the power plant of the water surface ship works, the outlet section of the engine inclined tube body is below the water surface, and the controllable water inlet is below the water surface. According to the invention, the high temperature, high voltage, high speed fuel gas and detonation waves are generated by adopting the detonation tube to propel the fluid to be exhausted to generate push power.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a power device for water surface ships. Background technique [0002] At present, surface ships mainly use gas turbines as power plants. When the gas turbine is working, isobaric combustion is carried out in the combustion chamber, which generates high-temperature and high-pressure gas to drive the turbine to rotate at high speed, and the turbine drives the propeller to output usable work through the reducer shaft. The main problem of using a gas turbine as a power plant is: the isobaric combustion in the combustion chamber, the combustion thermal efficiency is not high, and the thermal cycle efficiency of a general gas turbine is 27%; using a propeller as a propeller, the direction of water flow is at a certain inclination angle to the propeller axis. The speed of water flow can be decomposed into a backward axial speed and a circumferential speed perpendicular to the axis, and...

Problems solved by technology

[0004] In order to solve the problem that the thermal cycle efficiency is not high and the power is limited when the gas turbine is used as the power plant in the existing surface ships, the present invention proposes the use of a pulsating jet engine as the power plant of the water ship, and its working principle is that the detonation wave generated by the engine will The fluid in its propagating direction is discharged at high speed, so as to obtain the reverse thrust to do work externally
