STUDY OF VARIABLE TURBINE GEOMETRY FOR SMALL GAS TURBINE ENGINES

Abstract

An analytical investigation of the transient and steady-state performance of a series of gas-turbine engines utilizing variable geometry in the turbine was completed. Shaft-power engines with and without regeneration and incorporating either free- or single-shaft configurations were investigated at compressor pressure ratios of 10 and 16. In addition free-shaft, simple- cycle, high bypass, fan engines were evaluated using the 10- and 16-pressure- ratio gas generators for the high pressure system. Extensive use was made of the IBM 7094 II digital computer to analyze both the turbine and overall engine performance.
