The overall weight of a modern high bypass ratio large thrust engine, such as the Rolls-Royce Trent family is dominated by the weight of the fan system. Rolls-Royce is developing a composite fan system for deployment in future civil gas turbine engines, with the primary aim to deliver a significant weight saving. This enables substantial improvements in specific fuel consumption (sfc), thereby contributing to reduced emissions and achievement of the ACARE targets.Improving the propulsive efficiency requires ultra-high engine bypass through design of the fan system, which means increasing fan diameter and potentially weight. With the introduction of a composite fan system an overall weight saving of >300 kg is possible, which equates to a 0.2% sfc reduction.This was a collaboration between Rolls-Royce, GKN Aerospace and University of Bristol. This project developed future design and modelling capability and developed key capabilities for the overall fan system, ensuring its operation is robust and reliable. This included developing a robust liner system that protects the casing and allows the overall structure to be as lightweight as possible. The project also developed robust tip-rubbing capability for the blade tip; development of fire-proofing the composite casing structures; and development of Non Destructive Testing (NDT) capabilities to inspect the containment case and liner. This project is an enabler for the next generation of aero gas turbines and offers enhanced product competitiveness through reduced engine weight, leading to reduced fuel burn and hence lower environmental emissions. The project has significantly grown the capability of Rolls-Royce in the domain of composite technology. A Composite Technology Hub has been established in Bristol; the advanced manufacturing centre will be at the forefront of developing the next generation of fan blades and fan cases.

现代高涵道比大推力发动机（例如劳斯莱斯遄达系列）的总重量主要由风扇系统的重量决定。罗尔斯·罗伊斯正在开发一种复合材料风扇系统，用于未来民用燃气涡轮发动机的部署，其主要目标是显着减轻重量。这使得特定燃料消耗量 (Sfc) 得到显着改善，从而有助于减少排放并实现 ACARE 目标。提高推进效率需要通过风扇系统设计实现超高发动机旁路，这意味着增加风扇直径和潜在的重量。通过引入复合材料风扇系统，总体重量可以减轻超过 300 公斤，相当于减少 0.2% 的 sfc。这是劳斯莱斯、GKN 航空航天公司和布里斯托大学之间的合作。该项目开发了未来的设计和建模能力，并开发了整个风扇系统的关键功能，确保其运行稳健可靠。这包括开发坚固的衬里系统，以保护外壳并使整体结构尽可能轻。该项目还为叶片尖端开发了强大的尖端摩擦能力；防火复合套管结构的开发；开发无损检测（NDT）能力来检查安全壳和内衬。该项目是下一代航空燃气轮机的推动者，通过减轻发动机重量来提高产品竞争力，从而减少燃油燃烧，从而降低环境排放。该项目显着增强了劳斯莱斯在复合材料技术领域的能力。在布里斯托尔建立了复合材料技术中心；该先进制造中心将处于开发下一代风扇叶片和风扇外壳的最前沿。
