Recent General Electric Engine Development Testing for Improved Service Life 780990

More exact simulation of engine in-service operating conditions by accelerated development test program improvements-T700/F101/F404/CFM56/CF6-are reviewed for lessons learned towards earlier identification/solution of engine life extension problems. Improved design features, improved analysis and test simulation of mission cycles, improved component test techniques and, in general, increased emphasis on demonstrating required minimum service life prior to Production are briefly discussed. Possible future direction of these efforts is indicated for consideration in General Engine Specification revisions.
