Nonlinear Modelling and Validation of an Aircraft Gas Turbine Engine
In this paper the orthogonal estimation algorithm is used to estimate a NARMAX model for an aircraft gas turbine. The performance of the model is validated using a range of small and large signal tests and by examining the model’s static and dynamic characteristics. The NARMAX representation allows the direct mapping to the frequency domain by computing the Higher Order Frequency Response Funct...
متن کاملAIAA 2003–3698 Aircraft Gas Turbine Engine Simulations
The Center for Integrated Turbulence Simulations (CITS) was created in October of 1997 under the sponsorship of the Department of Energy (DoE) Accelerated Strategic Computing Initiative (ASCI) Alliance program. The over-arching problem to be solved by this Center is the detailed, high-fidelity simulation of the flowpath through complete aircraft gas turbines including the compressor, combustor,...
متن کاملSensor Selection Optimization for Aircraft Gas Turbine Engine Health Estimation
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...
متن کاملMultistage Condition Monitoring System of Aircraft Gas Turbine Engine
Researches show that probability-statistical methods application, especially at the early stage of the aviation Gas Turbine Engine (GTE) technical condition diagnosing, when the flight information has property of the fuzzy, limitation and uncertainty is unfounded. Hence the efficiency of application of new technology Soft Computing at these diagnosing stages with the using of the Fuzzy Logic an...
متن کاملGas Turbine Engine Behavioral Modeling
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...
