Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

Sensor selection optimization can lead to significant improvements in the controllability and observability of a dynamic system. The aim of this research is to investigate optimal or alternate measurement sets for aircraft gas turbine engine health parameter estimation. A brute force search for the best sensor set is too computationally expensive. Therefore, a Monte Carlo approach is used to pe...

Superalloys are a class of materials that possess stable microstructures at elevated temperatures due to the presence of coherent L12 ordered γ’ precipitates spatially aligned along elastically soft directions in a face centered cubic (FCC) γ matrix [1]. Nickel-base superalloys are used in a variety of applications such as in turbine blades of aircraft engines and land-based turbine engine [1]....

This report contains the work of the capstone design team, assigned to design a comprehensive, cost effective, monitoring system for gas turbine engines. The main objective of the design was to produce a system capable of detecting and recording only special conditions or events. As a sample engine, the SR-30 gas turbine was used. A simulation of the engine using GSP software provided a model. ...

This paper develops and validates a power flow behavioral model of a gas turbine engine with a gas generator and free power turbine. “Simple” mathematical expressions to describe the engine’s power flow are derived from an understanding of basic thermodynamic and mechanical interactions taking place within the engine. The engine behavioral model presented is suitable for developing a supervisor...
