Iatsko L. The complex diagnostic of technical conrition for aviation engines on static and dynamic work modes

Dissertation is devoted the improvement of methods of parametric and vibration diagnostics for the decision of tasks of determination of the technical state of billows of GTE in the process of exploitation on the different modes, determinations and localizations of their damages. The mathematical model of precipice of billow is got. Dependences of diagnostic sign are certain on frequency of rotation on different heights, scope values are formulated for the different modes of exploitation. The method of removal of casual constituent of measuring of frequency is offered on the basis of wavelet filtration. The end of ele-ments model of the damaged billow and billow is developed with a disk. The improvement of dynamic model of billow is executed with a crack by introduction of corner, determining position of crack in relation to the vector of vibration. The scheme of the system of automatic defense, methods of tuning and testing, method of verification of ca-pacity in the process of stand tests, is developed. Software is developed for the intellectual system of measuring and treatment of information.
