SAMULET Project 1 - High Efficiency Turbomachinery

该项目旨在通过提高燃气轮机的效率来减少其对环境的影响。它还旨在降低其生命周期成本。预计未来10至15年，航空运输需求将翻一番，20年内将翻三倍。为了实现持续增长，同时限制未来航空运输对环境的影响，欧洲航空研究咨询理事会（ACARE）为燃气轮机的排放水平设定了具有挑战性的目标。为了解决这些问题，需要提高效率和增加工作温度能力。该项目预计减少的燃料消耗可以转化为每架飞机每年减少836吨二氧化碳排放。要实现这一大幅度削减，就必须采取多方面的办法。因此，该项目被分为许多工作包（WP），涵盖冷却，空气动力学，气动力学相互作用和材料。后者为前者的包装提供了更宽的设计空间，因此所有包装都是相互连接的。该项目是更大的SAMULET方案的一部分。与以前定义较窄的研究相比，该方案正在采取的跨学科方法预计将提供更大的技术能力。

The project aims to reduce the environmental impact of gas turbines by improving their efficiency. It also aims to reduce their lifecycle cost. Air transport demand is predicted to double in the next 10 - 15 years and triple in 20 years time. In order to enable sustained growth, whilst limiting the environmental impact of air transport in the future, the Advisory Council for Aeronautical Research in Europe (ACARE) has set challenging targets for emission levels from gas turbines. Improvements in efficiency and increased operating temperature capability are required to address these issues. The reduction in fuel burn anticipated from the project can be converted to a reduction of 836 tonnes of carbon dioxide emitted per aircraft per year. To achieve this large reduction a multifaceted approach is necessary. Hence, the project is split into a number of work packages (WP) covering cooling, aerodynamics, aeromechanical interaction and materials. The latter facilitates a wider design space for the former packages and hence all packages are interlinked. The project forms part of the larger SAMULET programme. The cross-disciplinary approach being taken, in this programme, is expected to deliver greater technical capability when compared to previous more narrowly defined research.
