Book Description
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.

Book Description
This report describes a formal method to quantify structural damage tolerance and reliability in the presence of a multitude of uncertainties in turbine engine components. The method is based at the material behavior level where primitive variables with their respective scatter ranges are used to describe behavior. Computational simulation is then used to propagate the uncertainties to the structural scale where damage tolerance and reliability are usually specified. Several sample cases are described to illustrate the effectiveness, versatility, and maturity of the method. Typical results from this method demonstrate that it is mature and that it can be used to probabilistically evaluate turbine engine structural components. It may be inferred from the results that the method is suitable for probabilistically prediciting the remaining life in aging or deteriorating structures, for making strategic projections and plans, and for achieving better, cheaper, faster products that give competitive advantages in world markets.

Book Description
Three specific schemes aimed at increasing critical part lives of a military engine are described. Quantitative life extensions, as a result of implementing these schemes, are given when appropriate. Any of these schemes could be applicable to other engines when sufficient field usage data are available.

Book Description
Diminishing budgets for new weapon systems are creating% pressure within NATO nations to keep legacy aero engines in operation well beyond their service life expectancy. Techniques for safely extracting maximum usage out of aging components in these engines, to reduce maintenance costs, are discussed. The mechanisms responsible for the aging of components are described. The different strategies that fleet managers may adopt for extending component lives economically and safely are identified and discussed from an operator's perspective. The paper borrows from recent NATO activities in this area and shares related Canadian experience. It presents and discusses a qualification methodology for component life extension developed in Canada for the Canadian Forces.
