Abstract:

A significant fraction of the life-cycle cost of an aircraft engine can be attributed to the high replacement cost of engine components that are damaged in service. This Workshop addresses component damage management and ways to reduce operating costs by extending component lives without sacrificing safety. Life extension options available to life cycle managers include 1 improving the durability of components through material substitution, or the addition of protective coatings, 2 returning damaged parts to service after welding or brazing of cracks, 3 eliminating microstructural damage by reconditioning treatment, and 4 implementing new, more efficient lifing techniques for critical parts, such as turbine discs, based on the condition of the parts.
