Modeling Behaviour of Damaged Turbine Blades for Engine Health Diagnostics and Prognostics
The reliability of modern gas turbine engines is largely due to careful damage tolerant design a method of structural design based on the assumption that flaws (cracks) exist in any structure and will continue to grow with usage. With proper monitoring, largely in the form of periodic inspections …
