YaKUShENKO O. Automated maintenance monitoring the remaining working life of aviation GTEs by the criterion of turbine rotor blades' damage

The methodology of checking the remaining working life of GTE by the criterion of long strength of turbine rotor blades was formed. It is taking into account the stochastic nature of damage . The procedure was created for the estimation of influence of technical state (TS) of GTE and peculiarities of its maintenance to the accumulation of damages in its details. The procedure was developed for the prediction of remaining working life of aviation GTE with the consideration of its TS and peculiarities of forthcoming period of maintenance. The mathematical model of working process of GTE ПС-90А and the algorithm of coordination it with the parameters of engine functioning were developed. The procedure was developed for the producing the regression dependences of the parameters of loading of GTE details from the parameters of its working process.
