    摘要： A portion of the internal energy of a mass flow of a compressible fluid, such as air, is transformed efficiently into greatly increased flow kinetic energy by passing the flow through a set of converging nozzles in a cylindrical rotor; this accelerates the isentropic flow to sonic speed generating large thrust. The nozzle thrust generates torque, thus rotating the rotor which is coupled to a power take-off for doing useful work. The mass flow of air through the apparatus is supplied by a vacuum pump.

    摘要： A turbine controls testing device is disclosed that can be adapted to test the control systems of most turbine rotors without the use of steam. The turbine controls testing device comprises an operator control system, a drive motive power assembly and a purge gas assembly. The novel device controllably spins, accelerates, and decelerates a turbine with a relatively high level of precision, minimizing the likelihood that, in the event an overspeed mechanism malfunction occurs, the turbine will be damaged as a result of sonic velocity or any other mechanical failure.

    摘要： This invention relates to a clean, efficient, substantially isentropic method and apparatus for transforming the internal energy of a mass flow of a fluid, such as air, into increased flow kinetic energy and then efficiently transferring this additional kinetic energy to a power take-off means for doing useful work. The acceleration of the air flow is accomplished by passing the air flow through a set of converging nozzles which generate thrust; the nozzle thrust is then transformed into torque which turns a rotor which is coupled to a power take-off means. The method and apparatus can be made to be self-sustaining.
