Evaluation of a change in GT blade material

FE stress analysis of GT blade

Client:

  • A UK turbine blade manufacturer

Objective:

  • Evaluation of the effect of a change in material on the natural frequency of the blade

Approach:

  • Comparison of materials density and blade stiffness
  • Finite element study of blade dynamics, modelling the blade and fixture

Benefits:

  • Changes in blade dynamics demonstrated to be within design limits
  • Optimum balance between blade cost and performance achieved
