Are Management Problems in the Acquisition of Aircraft Gas Turbine Engines Being Corrected

摘要

Recent problems with fighter/attack aircraft engines have been primarily due to the development concepts, procedures, and practices that did not provide the time and money to (1) adequately develop the engines before production and use and (2) bring promising technology up to the point that it was ready for applications in new engines. Other major factors that adversely affected engine development were: inadequate definition of the engines' usage and, consequently, the inability to design engines to their expected usage and to verify the design by testing to that usage; emphasis on performance requirements with a resulting lack of standards, data base, and analytical procedures to achieve a balance among performance, operability, reliability, durability, and costs; and inadequate flight testing of engines.
