All 6 gas turbines were evaluated with the same formulas, however compressor and turbine efficiencies and pressure losses were altered for all gas turbines to fall in line with the type of engine. The Solar Saturn is a simple cycle gas turbine with 6.5 pressure ratio Pr and a non cooled ...

(RAE) undertook efforts to design an efficient gas turbine for jet propulsion of aircraft. The unit produced by Whittle’s group worked successfully during tests; it was determined that a pressure ratio of about 4 could be realized with a single centrifugal compressor running at roughly 17,000 ...
nificant deterioration problem faced by gas turbine operators is compressor fouling. The effect of compressor fouling is a drop in airflow, pressure ratio, and compressor efficiency, resulting in a “rematching” of the gas turbine and compressor and a drop in ...
