Compared with prior art, the utility model has the advantage of: the technology of the technology of motor and pump is combined, change the hydraulic jet propulsion system axial-flow pump of aircraft (boats and ships) and the turning moment mode of screw in prior art, by traditional pipe box changing into from the blade tip by rotating shaft rotation in the heart of oar, turned to realize rotation; Due to when work, by galvanomagnetic effect, realize oar (fan) leaf and rotate, make can firmly connect without mechanical rotating shaft between the main frame of boats and ships and screw, axial-flow pump, for boats and ships provide without rotating shaft propulsion plant, make the cabin design of boats and ships can be more flexible.And electronic (screw, axial-flow pump) of the present utility model machine, because motor can have reverse reverse and adjustable speed, can cancel down thus along back gear, and make the boats and ships that adopt motor of the present utility model to make hydraulic jet propulsion system can cancel down bucket device in design.
If cooling, heat dissipation technology problem that motor of the present utility model is resolved, and adopt aeronautical material manufacture, motor of the present utility model also can be used as aero-engine, owing to adopting power technology, compare with existing aero-engine, there is no tail spray thermal source, can make aircraft in designing for manufacturing, can do to make upper and lower, all around 129600 degree move operations and the submerged operation of can plunging into the commercial sea as cross simultaneously.
Because the turning moment transmission method of screw, axial-flow pump changes the pipe box mode of turning into by traditional rotating shaft, turning moment You Zhou center (propeller hub) the internal diameter transmission that has changed screw makes the blade tip, external diameter transmission into, relatively pipe box is turned and rotating shaft effect, theoretical according to the mechanical balance of lever; If screw axial flow Beng Zhou center is a fulcrum, the piston stroke of marine main engine is lever length on one side.
The external diameter that pipe box is turned is the length of lever another side, the external diameter that pipe box is turned so and the ratio of piston stroke, it is exactly the effect parameter that pipe box is turned, therefore, if when the screw of same parameters, 10,000 horsepowers of shaft power of its needs of axial-flow pump, it is that routine screw, the output power of motor of axial-flow pump at least can be contracted between 4,000 horsepowers to 1,000 horsepowers less even that its pipe box is turned.Like this when a screw, 10,000 horsepowers of shaft power main frames of its needs of axial-flow pump, it can drive generator with the main frame of 2,000 horsepowers, thereby through the galvanomagnetic effect drive pipe box of motor, turn and drive screw rotation again, not only improved the energy efficiency of boats and ships, realize and saving energy and reduce the cost, and manage simple and convenient.
