Abstract
Abstract A power producing constant speed rotary turbine in which an elongate shaft is rotatably supported in longitudinally spaced, axially aligned first and second housings that have a housing assembly disposed thereinbetween. The first housing rotatably supports a power take-off that is driven by a series of reduction gears operatively connected to the shaft. The second housing envelops an output power turbine rotor defined by a series of thin, circular, coaxially aligned, laterally spaced discs of high temperature metals or high temperature ceramic such as hot pressed silicon nitride that are operatively connected to the shaft. A compressor rotor is mounted in an intermediate position on the shaft and rotates within the housing assembly, which assembly has an air inlet therein. As the compressor rotor rotates in the housing assembly, air is discharged to first and second groups of diffuser tubes that extend to first and second volute casings. The first and second volute casings are in communication with first and second combustion tubes in which first and second burners are disposed.
