Aerospace Information Report 1939 Trial Application 861787
The proposed AIR 1939, “Aircraft Engine Life Cycle Cost Guide,” states the need for a methodology capable of relating input and output data on a consistent basis. This paper demonstrates that a methodology consistent with the proposed guidelines of AIR 1939 is practical. A generic example was constructed based on the design-to-cost/life cycle cost (DTC/LCC) requirements for an Allison engine full-scale development program. The example is presented using concepts and terminology from AIR 1939 in order to demonstrate the applicability of the document.
