Aircraft Engine Component Deterioration and Life Cycle Cost Estimation

Reducing the service elements of Life Cycle Cost (LCC) has become a key issue for aircraft engine manufacturers as more of their customers are moving to TotalCareTM style agreements (fixed cost per operational hour maintenance agreements). This paper makes efforts to build a link between the engine component deterioration (a key driver of LCC) and business led LCC estimation requirements. The techniques of both product and service cost estimation are firstly reviewed, followed by a summary of engine component deterioration life modeling methods. The paper concludes by giving a component deterioration driven cost estimation framework for engine life cycle.
