This paper presents the fuzzy logic computing for the design and implementation of fuel controller for gas turbine engines. For this purpose, a fuzz controller is designed in order to be implemented on an electronic control unit where it is used to drive a servo operated fuel control valve. The fuzzy logic computing approach for different parts of the controller including fuzzification, rule base,...
This paper formulates and validates a novel methodology for diagnosis and isolation of incipient faults in aircraft gas turbine engines. In addition to abrupt large faults, the proposed method is capable of detecting and isolating slowly evolving anomalies (i.e., deviations from the nominal behavior), based on analysis of time series data observed from the instrumentation in engine components. The...
Applying computational science and engineering to the design and analysis of high-performance compressors makes it possible to understand unsteady flow effects in gas turbine engines. Simulations have produced numerical data of greatly improved geometric, physical, and numerical fidelity than previously possible, helping next-generation engines achieve unprecedented performance.
