Description
Technical Field
The invention belongs to the technical field of submarine propulsion, and particularly relates to a front-rear dual-drive all-electric permanent magnet shaftless vector propulsion structure for a high-speed submarine.
Background
The resistance generated by the submarine in the underwater navigation process comes from the composite resistance generated by fluid (water), and the rechecking resistances mainly consist of: differential pressure resistance, frictional resistance, wave making resistance, and protrusion resistance. The pressure difference resistance is also called vortex resistance, and means that when the submarine is in navigation, fluid can form a shuttle type fluid through the surface of the submarine, and pressure difference can be generated in the whole structure of the shuttle type fluid due to different reasons such as fluid flow rate, direction and the like. The ideal shuttle-type fluid is completely symmetrical except for the flow direction, and because of the symmetry, no pressure difference exists in all directions of the ideal shuttle-type fluid. However, due to the protruding structures such as a command tower, a horizontal wing, a propulsion pump and the like in the structure of the submarine, the appearance of the submarine is not an ideal shuttle-type structure, and the flowing form mainly comprises laminar flow, turbulent flow (turbulent flow) and the like, wherein the turbulent flow phenomenon and a large number of bubbles generated by cutting fluid by a propeller are main causes of differential pressure resistance, and the phenomena are mainly concentrated at the tail part of the submarine, so that serious asymmetry of front pressure and back pressure is generated; frictional resistance refers to friction force generated by the submarine and seawater during navigation, and the main reason of the frictional resistance is caused by viscous force generated by fluid and an object moving in the frictional resistance, and the frictional resistance is mainly related to surface tension of the fluid and surface tension of a moving object; the protrusion resistance refers to resistance caused by protruding parts such as a submarine command tower, a propeller and the like in a fluid environment; wave making resistance refers to resistance to submarine caused by sea wave vibration, which is smaller and smaller to negligible with the increase of submergence depth. This resistance is not the main cause of the resistance of the submarine to underwater navigation. In order to overcome the above resistance, the structural optimization of a command tower, a propeller and the like of the submarine is almost the same; friction resistance currently develops a supercavitation submarine, and an oversized air bubble is manufactured at the head of the submarine to completely wrap the surface of the submarine, separate the submarine from seawater, and reduce friction resistance. Great results are achieved on a small body volume scale, but because air bubbles cannot be made very large, large-volume objects such as submarines cannot be wrapped, and success on the submarine body volume scale has not been achieved. For differential pressure resistance, the existing solution is mainly focused on indirectly solving the differential pressure resistance by overcoming the protrusion resistance and the friction resistance, and no other very effective technical means exists.
