Abstract Scope |
Nickel-based superalloys remain the essential enabling materials technology for high temperature componentry in gas turbines. Alongside architectural design, nickel alloys have permitted substantial improvement in specific fuel consumption and durability; indeed the Rolls-Royce Ultrafan aero engine is set to be ~25% more fuel efficient than the first generation Trent Engine (Trent 700) and 10% better than the XWB - currently the world’s most efficient aero engine [1]. There exists a multitude of complex alloy compositions consciously optimised over 70+ years which have been designed or selected for specific applications. The use of certain constituent elements or processing methods for targeted property improvement must be considered in the context of the full product lifecycle to assess the sustainability trades of new manufacture and through life impact on customer and business value. Original Equipment Manufacturers (OEMs) are now increasingly contracted to deliver ‘customer outcomes’ rather than just the equipment. The principles of effective Asset Management and Through Life Engineering Services (TES) are discussed and supported by case studies pertaining to lifecycle management, particularly repair methodologies. ‘Digital Twins’ are a key enabler to optimising the Through Life Engineering Services value levers; understanding/controlling the physics of how superalloys degrade in use is pivotal to delivering better customer, business, and sustainability outcomes. The paper presents a framework for optimising product offerings whilst simultaneously working towards a sustainable future. |
