Creep Life Prediction for Aero Gas Turbine Hot Section Component Using Artificial Neural Networks

Abstract: Accurate and reliable component life prediction is crucial to ensure safety and economics of gas turbine operations. In pursuit of such improved accuracy and reliability, model-based creep life prediction methods have become more and more complicated and therefore demand more computational time although they are more flexible in applications, in particular for new gas turbine engines. Therefore, there is a need to find an alternative approach that is able to provide a quick solution to creep life prediction fo… Show more

“…From the linear GPA method developed by Urban in the late 1960's [13], a series of GPA methods were proposed, such as an adaptive nonlinear GPA method [7], artificial neural networks [3], rule-based expert system and rule-based fuzzy expert system [11], and genetic algorithm [4,12,17]. The merit of artificial intelligence methods, such as neural network, rough set [14], Bayesian network [9,10] and rule based expert system, is that they do not need a gas turbine performance model, as only the relation information between fault symptom and degradation is needed.…”

“…These include support vector machines (SVM) [1,[7][8][9], Bayesian forecasting [10][11][12], Kalman Filters [10], state-space models [12], artificial neural networks [13][14][15][16], independent component analysis [17], regression techniques [18], Dempster-Shafer regression [1] and one parameter double exponential smoothing [10]. These techniques can be classified into two types: (i) physics based modelling approaches, and (ii) data driven models [5,[19][20][21].…”
