Performance optimization of gas turbine engine

Engineering Applications of Artificial Intelligence, 2005
Performance optimization of a gas turbine engine can be expressed in terms of minimizing fuel consumption while maintaining nominal thrust output, maximizing thrust for the same fuel consumption and minimizing turbine blade temperature. Additional control layers are used to improve engine performance. This paper presents an evolutionary approach called

The Gas Turbine Engine

1981
In order to minimise fuel consumption and increase thrust, the operating temperatures of aero engine gas turbines have increased significantly over the last 30 years.

A Computational Method For Gas Turbine Engines

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
Designing and developing new aerospace propulsion systems is time-consuming and expensive. Computational simulation is a promising means for alleviating this, due to the flexibility it provides for rapid and relatively inexpensive evaluation of alternative designs, and because it can be used to integrate multidisciplinary analysis earlier in the design

Sulfidation in Gas Turbine Engines

CORROSION 1975, 1975
Within the past two decades the corrosion problems associated with the use of operating at elevated temperatures became as important as the high temperature mechanical properties such as strength, resistance to creep, etc. The increases in gas turbine inlet temperatures, metal use temperatures, and the desirability to utilize lower costs, lower grade ...

Aerofoils For Gas Turbine Engines

The Journal of the Acoustical Society of America, 2011
An aerofoil 26 for a gas turbine engine (10, Fig. 1) comprises a cavity 38, a cellular material 42 located in the cavity 38 for stiffening the aerofoil 26, and a vibration damping medium 44 located in the cavity 38 for damping the aerofoil. The cellular material 42 is preferably a metal foam bonded to the inner surface 34a, 36a of the hollow aerofoil ...
