Work Capacity of Gas Turbine Blades Loaded by Multiple Start-Ups,

Abstract

The report studies the effect of natural engine start-ups on the work capacity of gas turbine rotor blades. Rotor blades of the third stage in a turbine from a AI-20 engine, which had previously accrued operational times of 2375 and 6000 h, were loaded in multiple start-up regimes. Residual life and the logarithmic decrement in vibrations were the parameters used to describe the strength of the rotor blades. (Author)
