Turbojet pump-water jet engine is a solution for the drive of vessels on water and under water, for ships and submarines, and the achievement of their speeds above 50 m/s. The basic construction contains pump box (1) which is transformed in the back part into the Venturi tube (16). The drive three phase asynchronous electric motor (8,9,10,11) that uses electric currency of high tension and higher operating frequencies, is having small volume measure for power realized, drives axial pump rotors (5,13) and achives great flows. The accelarated great water mass in Venturi tube gives great buoyacns. When usung flat axially symmetrical blade of elliptical cross-section, the pump is turned in both directions, so on both ends of the boxes, Ventiri tubes (16) are placed for two direction jet effect that is important with submarines. Another embodiments are that the pump drive is achieved by schafts axially or radially placed related to axis of its schaft (8), and driven from the inside of the vessel. |
