Abstract:

This report summarizes Teledyne CAEs experience and conclusions in developing reduced-cost adaptive components, airframe interface requirements, and integrated systems plans under the AFAPL-sponsored Aircraft Propulsion Subsystem Integration APSI program. The APSI program is directed to evolving the Teledyne CAE Model 555 ATEGG into a turbofan Joint Technology Demonstrator Engine JTDE. Reduced cost of engine ownership is one major objective of the APSI program. It was, therefore, deemed advisable to summarize that task into this document. Section 2.0 of this report provides an overview of engine ownership costs, as perceived and evaluated by Teledyne CAE, in accomplishing APSI-program tasks. Section 3.0 describes the application of the cost reducing methodology, including the results of iterating the baseline and scaled engines and applying Design-to-Cost DTC methods during their design. Section 4.0 advances 18 specific cost reduction topics, ranging from materials technology through candidate cost-reducing components to possible savings resulting from engine model specification changes. Section 5.0 addresses the subject of engine ownership cost reduction as an evolving methodology. Comments are offered on its present status and objectives. Some suggestions for improving the precision and usefulness of Design-to-Life-Cost methods are submitted.
