DELICE (Design of Engineered Lightweight Innovative Casings for Engines)

发动机轻量化创新机匣设计（德利采）在Trent系列三轴发动机的成功基础上，劳斯莱斯宣布有意开发UltraFan™，这是一种新型超高涵道比（UHBR）齿轮传动结构。这提供了推进效率的显著提高，并将用于2025年及以后的下一代飞机。这种新结构的一个基本推动力是大直径、低速、低压比风扇系统的开发。该项目将设计和制造世界上最大的复合材料风扇外壳，以支持UltraFan™演示计划。劳斯莱斯将与牛津大学国家复合材料中心合作，利用英国制造服务供应链来实现这一总体目标。

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.
