PLANNING THE DEVELOPMENT AND QUALIFICATION PROCESS FOR THE NEXT GENERATION OF HIGH TECHNOLOGY AIRCRAFT ENGINES

From the perspective of Detroit Diesel Allison (DDA), the development process for the high-technology aircraft engine is addressed in view of recent military engine experience and current procurement policies, and time and funding constraints. The propulsion system development process comprises: definition of requirements, selection of appropriate technology, design and fabrication, verification of characteristics, and resolution of problems identified during the verification phase. During the last decade, new analytical and testing tools and a systematically evolving technology base have greatly improved the development process. An increasing emphasis has been placed on cost, durability, and reliability, as well as a continued emphasis on performance. The new weapon procurement process defined by OMB (Office of Management and Budget) A109 will extend the development time required between authority-to-proceed and a milestone equivalent to the Model Qualification Test, the last step in the traditional four-year development process. The development approach, consistent with the procurement process, includes a preview of engine requirements in the flight test program prior to the initiation of full-scale engineering development. The evaluation of the relative merits of efforts being conducted by DDA as part of advanced development and Advanced Turbine Engine Gas Generator/Aircraft Propulsion System Integration programs are routinely evaluated using total-weapon-system life cycle cost (LCC). The LCC perspective is carried through into the engine design and development phase in the form of a design-to-cost discipline, an effective tool for managing product cost control from engine configuration definition through development and into production.
