A turbine for generating power has a rotor chamber, a rotor rotatable about a central axis within the rotor chamber, and at least one nozzle for supplying a fluid from a fluid supply to the rotor to thereby drive the rotor and generate power. The flow of the fluid from the nozzle exist is periodically interrupted by at least one flow interrupter means, thereby raising a pressure of the fluid inside the nozzle. A thermo-dynamic cycle is also disclosed including a compressor, a first turbine downstream of the compressor, a heat exchanger located downstream of the first turbine and operable to reject heat from the cycle to another thermodynamic cycle, an evaporator downstream of the heat exchanger and a second turbine downstream of the evaporator and upstream of the compressor.

A jet aircraft engine having an improved turbine section with curved intake manifolds to direct combustion gasses from the engine's combustion chamber into the turbine housing on a chordal flow path through the turbine generally perpendicular to the turbine rotor's axis of rotation. The turbine rotor has a number of radially extending turbine blades for transmitting energy from the combustion gasses to shaft work to drive the engine's fan and compressor. Exhaust manifolds can also be provided, directing the flow of exhaust gasses from the turbine to the engine's intake, and having noise and emissions control capability.

A governor device for controlling the speed of rotary devices is disclosed. The governor device is a valve operated by centrifugal force to control a pressurized fluid through the nozzles of a turbine rotor. The valve comprises a rotary chamber having an opening outwardly of a resilient valve member therein, the resilient valve member being movable by centrifugal force to control flow through said annular chamber, said annular chamber being part of the passageway of the pressurized fluid flow through said turbine rotor nozzles.
