Life extension of critical ‘Group A’ components with a view to implement robust process for protection of these components by introducing protective tooling & management of this tooling into the build process for Trent 900 engines at Rolls Royce Plc Derby’s civil aerospace operation

| Summary: | Attributed to the high engine operating temperatures and stresses at which the Trent 900 critical ‘Group A’ parts operate, the predicted damage tolerant life for a number of components is tending toward the engine shop-visit interval.
This report provides an introduction to the issue, discusses the scope of the project and details the robust Six Sigma’s DMAIC strategy followed throughout the project duration. This project brings number of improvement proposals to reduce the possibility of damage occurring to critical parts during their build, assembly and overhaul process. The build processes of the High Pressure Turbine Disc (HPTD) have been examined in detail. The strategy followed allowed to identify the areas in the build process where turbine disc is vulnerable to the potential of damage. Root causes of the problems have been identified and recommendations have been proposed for high priority areas.
Although this report primarily focuses on the Trent 900 HPTD build process, many of the recommendations proposed have potential for read-across to other critical component of engine to reduce the potential of handling damage in the process. |
