Abstract: | In this paper, the theoretical studies of stress concentrations in the compressor blades of aircraft gas turbine engines damaged
due to foreign objects ingestion into the gas-air flow path are presented. The technique of three-dimensional finite-element
calculations of the theoretical stress concentration factor in the damage region has been developed. We also examined the
influence of geometrical blade parameters and damages (stress concentrators) upon the theoretical concentration factor and
suggest using a simple relation for its approximate assessment. |
