An Investigation into the Mechanics of Single Crystal Turbine Blades with a View Towards Enhancing Gas Turbine Efficiency
DE-FC26-01NT41344

In September of 2001 the National Energy Technology Laboratory entered into a cooperative agreement with Texas A&M University to investigate the mechanics of single crystal turbine blades with a view towards enhancing gas turbine efficiency.

The goal of this project is to develop a theoretical framework for the study of the inelastic mechanical response of single crystal alloys. Isotropic models describing creep and plastic flow will be extended to incorporate the crystallographic symmetry of single crystal super-alloys. The resulting model will allow analytical lifetime prediction and failure analysis that can then be used to improve component design and enhance the reliability of turbine blade structures. This model will offer the highest possible operating temperatures and will result in an overall increase in fuel efficiency.
