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.
