BASING OF PROVIDING POSSIBILITY OF AVIATION GTE STRENTH RELIABILITY AT THE BASE OF USING OF CONSTRUCTIVE SIMILARITY OF THE MAIN PARTS

O.V. Sheremetyev

In the article there was done the basing of providing possibility of aviation GTE strength reliability at the base of using of constructive similarity of the main parts. There were considered calculating-experimental investigation results which testify that tensity comparison should be done at the same type zones of the stress concentration. There was exposed the method of approach with the accordance of which modeling can be done with the before hand unsimilarity phenomenon, if it is known the type of dependence of the unknown quantity from the determinant parameters. It was shown, that the presence of constructive similarity allowed to use accumulate experience for the new aeroengine creation.

Key words: gasturbine engine, constructive similarity, physical similarity, strength reliability, gradient of stress, modeling.
