COGS (COmposite Gears and Shafts)

COGS将开发混合金属复合材料航空发动机部件。这项技术将应用于主轴和周转齿轮箱内的行星齿轮。预计的重量减轻是显著的，从而减少了飞机的燃料消耗和二氧化碳排放。这项技术在其他部门也有应用，但这是第一次在航空发动机中同时用于主轴和行星齿轮。该项目将由劳斯莱斯领导，Romax将作为合作伙伴加入，Lentus Composites作为分包商，两家供应商都位于英国。

CoGS will develop hybrid metallic composite aero engine components. The technology will be applied to a mainline shaft and the planet gears within an epicyclic gear box. The predicted weight reduction is significant, resulting in a reduction in aircraft fuel burn and a reduction in CO2 emissions. There are applications of this technology in other sectors, however this is the first application within an aero engine for both mainline shaft and planet gears. The project will be led by Rolls-Royce, Romax will join as a partner and Lentus Composites as a sub-contractor, both suppliers are UK based.
