Blades account for as much as 42% of failures in gas turbines. This paper provides a practical treatment of the subject taking into account the complex nature of blading problems, influence of the operating environment, design factors and maintenance practices. Blading failure modes such as fatigue, environmental attack, creep, erosion, and embrittlement are addressed along with a synopsis of design tools to review blade reliability. Peripheral issues affecting blade integrity such as fuel and blade quality control are addressed. The Appendix provides applicable tools and formula that can be used by gas turbine users for design review and troubleshooting.
