Cycles To Failure

During transient operation, gas turbine blades are subjected to cyclic thermal stresses. For the first-stage blade of a Brown Boveri gas turbine, time-dependent temperature and stress distributions are computed by finite difference method to determine maximum total strain and to predict blade life failure. These calculations together with similarity conditions result in allowed temperature range fluctuations as a function of cycle time for a particular damage. The influence of important parameters like Biot and Fourier number was determined. Thermal fatigue tests of these blades in fluidized beds were carried out to investigate their resistance and to ascertain the usefulness of the computation technique. The predicted number of cycles to failure agreed quite well to those found in fluidized bed.
