Forecasting of the Effect of Potential Aero Engine Modifications on Life Cycle Cost
Abstract
The life-time of an engine normally extends to over 50 years. During this long period engine technology moves on. New materials, new calculation procedures and new design features become available. Introducing new technological elements is relatively easy during the early engine design phase. The more mature the engine design becomes, the more difficult it is to introduce new features, because they affect numerous other components or design parameters. It is not possible to incorporate a great number of new features into an engine which is already being operated by customers for financial reasons as well as from a logistical point of view. During the operation phase the benefit of introducing modifications must be thoroughly weighed with respect to quite a number of parameters. However, some modifications are important to be implemented due to flight safety reasons or due to cost saving aspects. The latter aspect will be discussed in this paper.
