Abstract: Almost from the inception of the gas turbine engine, airlines and engine manufacturers have sought an effective technique to determine the health of the gas-path components (fan, compressors, ...

Abstract: Gas turbine performance analysis programs convert raw measurements (thrust, fuel flow, gas path temperatures, and pressures) into engine and component figures of merit (e.g., specific fuel ...

Abstract: Manufacturers of gas turbines have searched for three decades for a reliable way to use gas path measurements to determine the health of jet engine components. They have been hindered in this ...
