Structural analysis of a cooled, directionally solidified turbine blade


Journal Article

Directionally solidifed, air-cooled turbine blades present new challenges to the structural design analyst. This paper describes an investigation of turbine blade failures encountered during a recent engine development program. The effect of wall tolerance variations on steady and vibratory stresses was determined using finiteelement methods (NASTRAN) combined with engine test data. This procedure successfully determined the failure mechanism and verified the subsequent redesign. © 1977, American Institute of Aeronautics and Astronautics, Inc. All rights reserved.
