Incorporation of the Turbine Engine Structural Integrity Program (ENSIP) has provided a more organized and disciplined approach to the durability related aspects of the engine demonstrator program. As a result, engine capabilities are more easily related and the number of durability problems is reduced. This is accomplished by increased contractor/customer interface in the design analysis, material characterization and verification testing of the engine programs. The demonstrator program has been affected by the ENSIP requirements, particularly the Damage Tolerance aspects. The design analysis is more complex while the configurations tend to be simpler with fewer notched locations. Materials are developed for improved crack propagation life while component and engine testing is expanded to verify this capability. The ENSIP specification effects increases in analysis, materials development, verification testing and durability.
