ABSTRACT:
A method and apparatus for the generation of high velocity fluid jets by using a rotor with attached discharge passages and nozzles. A working fluid is accelerated by using a rotating rotor, either of the free vortex type or of the forced vortex type, and the accelerated fluid is then passed through forwardly and inwardly extending passages, and discharged at high speed through openings that are inward from the rotor periphery. Fluids may be either liquids or gases. The high velocity fluid jet may be used where such jets are required, such as excavation, cutting, or as a source of thrust. The rotors may be also made multistage, if additional jet velocity is required.
