Исследование влияния положения промежуточной связи на прочностные характеристики лопаток сверхбольшой длины с двухъярусным бандажом

Abstract

A parametric model of two-stage ultra-long blade, which allows to vary the location of the snubber had been developed. Stress-strain state has been calculated taking into account the contact bandage links on the series of finite-element models of the cycle symmetric blades system. The obtained results allowed to determine the optimal location of the snubber.
