Helicopter Turboshaft Engine Residual Life Determination by Neural Network Method
ElectronicsA neural network method has been developed for helicopter turboshaft engine residual life determination, the basis of which is a hierarchical system, which is represented in neural network model form, consisting of four layers, which determines the numerical value of the residual life.
