Life Cycle Management Strategies for Aging Engines.

摘要

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.
