Design of Engineered Lightweight Innovative Casings for Engines (DELICE) Building on the success of the Trent family of three shaft engines Rolls-Royce has announced its intent to develop UltraFan™, a novel Ultra High Bypass Ratio (UHBR) geared architecture. This provides a significant improvement in propulsive efficiency and will be available for the next generation of aircraft 2025 and beyond. A fundamental enabler for this new architecture is the development of a large diameter, low speed, low pressure ratio fan system. This project will result in the design and manufacture of the world’s largest composite fan case in support of the UltraFan™ demonstrator programme. Rolls-Royce will work in partnership with the National Composites Centre the University of Oxford and utilise the UK manufacturing services supply chain to achieve this overall aim.
