Abstract

Aero-structure interaction during turbomachinery blade design has become an important area of research due to its critical applications in aero engines, land based gas turbines. Studies reveal that a small mistuning leads to stress build up through mode localization under operating conditions. This paper deals with a case study of Aero-structure interaction for a free standing HP blade of a gas turbine. Assuming 100 % fixity at blade root, the study involves critical parametric evaluations involved in achieving Mechanical Integrity in airfoil design and blade platform design. Mechanical Integrity involves stress checks, frequency margins, Campbell diagram, gross yield stress and so on, for design and off-design conditions for a given stage efficiency of 72 % in an Ideal HP compressor of a gas turbine engine.
