A new transient performance adaptation method for an aero gas turbine engine
, 2020The performance adaptation method based on the transient measurement data is proposed to generate a dynamic simulation model for gas turbine engines. The performance maps of the compressors and turbines are adjusted by using scaling factors.

Performance optimization of gas turbine engine
Engineering Applications of Artificial Intelligence, 2005Performance 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

A Computational Method For Gas Turbine Engines
43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005Designing 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
