Selection of the optimal value of the volume modes and duration of accelerated testing aircraft gas turbine engines in the multivariant applications

Abstract

The technique of choice, mode and duration of accelerated life tests of aviation gas turbine engines installed on several types of facilities that operate in various climatic zones and loading conditions is considered. Choice of test parameters is based on multi-criteria optimization that allows: to provide a guaranteed check engine reliability in all operational application options, to conduct differentiated "pass" in the accelerated testing of combined operational variants of engine material and minimize the time spent on testing.
