    Abstract: A nozzle for use with a rotor blade for a reaction drive type helicopter includes a first wall, a second wall opposing the first wall, and sidewalls extending between the first wall and the second wall enclosing a cavity having an upstream end and a downstream end. The nozzle includes an inlet section for receiving a gasflow at the upstream end. The distance between the first wall and the second wall reduces to a throat downstream of the inlet section. An expansion section extending from the throat, downstream thereof.

    Abstract: The present invention relates to an improvement of an axial turbine. Thereto, the present invention includes a submerged turbine 100 in which a fluid is filled in an interior thereof. The present invention also includes a colliding turbine 200 for ejecting a fluid with a high pressure to rotate blades. The structure of the turbine according to the present invention includes a submerged turbine, a colliding turbine, or a combination type turbine (in which a submerged turbine and a colliding turbine are combined). Accordingly, quality and reliability of the product are significantly improved to satisfy the operator.

    Abstract: A fluid motor is disclosed employed in a turbocharger to spin-up the turbocharger turbine independently of the existing exhaust gas pressure on the exhaust turbine wheel. A fluid turbine wheel is fixedly attached to the rotary mounted shaft of the turbocharger. Fixedly mounted nozzles directed at the fluid turbine wheel present fluid from a controlled source of pressurized fluid. A fixedly mounted collector receiving exhausted fluid from the fluid turbine wheel. The fluid is recycled from the collector to the controlled source of pressurized fluid and then back to the fixedly mounted. The fluid turbine wheel exhausts the fluid with residual energy to the collector. The controlled source of pressurized fluid includes a gear pump with an accumulator and a solenoid valve.

    Abstract: A rotor for a radial flow turbine has an impulse chamber (51) having an inlet defined in a circumferential surface of the rotor and a reaction chamber (62) having an outlet defined in the circumferential surface of the rotor. The impulse chamber is in fluid communication with the reaction chamber, and the reaction chamber outlet is axially displaced from the impulse chamber inlet.

    Abstract: A bladeless pressurized fluid turbine engine having a bladeless turbine, internal, concentric or circumferential shaft fluid ways which transmit pressurized gas to the turbine, and a pressurized fluid intake assembly. The intake assembly has a fixed outer housing, two or more shaft seals sealing between the shaft and the outer housing forming fluid supply chambers between adjacent shaft seals, and a pair of shaft bearings bearing between the shaft and the outer housing. The outer housing has one or more fluid intake ports for each fluid supply chamber and each shaft fluid way has a shaft fluid intake which is hydraulically connected to a fluid supply chamber.
