Abstract

The invention discloses a front and rear double-drive all-electric permanent magnet shaftless vector propulsion structure for high-speed submarines, which includes a front all-electric permanent magnet shaftless vector propeller, a submarine cavitation maintaining shell and a rear all-electric permanent magnet shaftless vector propulsion structure. The propeller; the front end of the front all-electric permanent magnet shaftless vector propeller is equipped with a front anti-marine life shell, and the rear end is equipped with a front three-dimensional vector rectifying nozzle; the rear all-electric permanent magnet shaftless vector propeller The front end is equipped with a rear anti-sea life shell, and the rear end is equipped with a rear three-way vector rectifying nozzle. The present invention effectively balances the pressure difference in front and rear directions generated during the advancing process of the submarine through the front all-electric permanent magnet shaftless vector propeller, significantly reduces the negative pressure resistance generated by the fluid during the advancing process of the submarine, and provides an auxiliary power source for the submarine. Reduce heat release, reduce noise and loss of efficiency, and the front and rear three-dimensional vector rectification nozzles can effectively reduce the turbulent flow phenomenon generated by the propeller, significantly increase the sailing speed, and enhance concealment.

Description

technical field [0001] The invention belongs to the technical field of submarine propulsion, and in particular relates to a front and rear double-drive all-electric permanent magnet shaftless vector propulsion structure for high-speed submarines. Background technique [0002] The resistance generated by the submarine during underwater navigation comes from the compound resistance produced by fluid (water), and these recheck resistances are mainly composed of pressure difference resistance, friction resistance, wave resistance and protrusion resistance. Pressure difference resistance is also called eddy resistance, which means that when the submarine is sailing, the fluid will form a shuttle-type fluid when it passes through the surface of the submarine. Due to different reasons such as fluid flow rate and direction, a pressure difference will be generated in the overall structure of the shuttle-type fluid. The ideal shuttle-type fluid is completely symmetrical except for the...
