Abstract
An efficiency enhanced turbine engine and method are disclosed for a turbine engine having a rotor and a fluid flow path that extends through compression, combustion, and expansion or turbine stages with fluid flowing through the fluid flow path driving the rotor. The turbine engine has one or more stator-rotor-stator assemblies, and use of a flat rotor disk with turbine blades provides simplicity in fabrication and operation. Increases in pressure during combustion above the pressure at the compression stage are prevented from flowing back to the compression stage and/or capturing of fluid during combustion enables elevation of the temperature and pressure while maintaining the fluid at near constant volume during combustion, both of which enhance the efficiency of the turbine engine. Fluid flow is preferably in a circumferential direction and the fluid is caused to reenter the rotor a plurality of times to provide cyclic exposure of the moving parts of the turbine engine to different portions of the engine cycle for reducing the average temperature of the moving parts and thereby allow higher compression ratios and combustion temperatures to also yield higher efficiency.
