[ Damage due to HCF ]
Damages in the HCF range (crack initiation at load cycle numbers above 105) are a major problem in engine construction. This is related to the high utilization of strength reserves required by the demands for minimum weight. Primarily affected parts are compressor and turbine blades. This is due to their characteristic geometry and the wide variety of powerful potential incitements (e.g. flow, rotor, rubbing). Unli…
