Structural Metallic Systems For Advanced Gas Turbine Applications

资源的减少和气候变化迫使工程设计师以更高的效率利用材料和能源供应。有人认为，如果要避免不可逆转的气候变化，必须减少60-90%的二氧化碳排放。目前，几乎所有的飞机推进和英国总发电量的三分之一以上都依赖于燃气轮机。与其他替代品相比，它们的灵活性和效率意味着，在可预见的未来，它们在发电中的应用预计将大幅增加。同样，预计航空旅行也将大幅增长，到2050年乘客数量预计将增加一倍或两倍。要在不使国民经济活动停滞的情况下大幅减少燃气轮机的排放，需要在很多方面采取紧急行动。这对英国来说尤为重要。它拥有欧洲最大的燃气轮机工业，仅次于美国，包括主要的发动机制造商，如劳斯莱斯、阿尔斯通和西门子，以及大约3000家公司供应合金、高完整性部件，如盘、叶片和轴，以及涂料和密封件。整个行业雇佣了40多万人，仅在电力部门就产生了20亿美元的出口。该计划的目的是通过识别和开发基于难熔金属的材料，如Mo和Co合金，同时进行短期研究以扩大ni基合金的用途，来应对这一挑战。这项工作将涉及材料开发和加工、微观结构和缺陷建模、这些高温材料的表征和预测的协调计划，旨在回答将使其潜力充分实现的基本问题。为了培养大量的研究人员，该项目汇集了来自6所大学的学者，他们在必要领域具有专业知识，并与罗尔斯·罗伊斯公司一起确保研究是适当的，并建立了开发路线。英国高价值工程部门的成功是一个需要提高公众理解的领域，以提高对冶金工程的普遍认识，并激发热情，鼓励更多的年轻人进入科学和工程领域。为了解决这个问题，我们设计了一个重要的公众参与项目，与这个研究项目一起运行

Dwindling resources and climate change are forcing engineering designers to utilise materials and energy supplies withever-greater efficiency. It is argued that cuts in CO2 emissions of between 60-90% must be achieved if irreversibleclimate change is to be avoided.At present, almost all aircraft propulsion and over 1/3 of the UK's total generating capacity rely on gas turbines. Theirflexibility and efficiency compared with the alternatives mean that their use in power generation is predicted todramatically increase for the foreseeable future. Similarly, a substantial growth in air travel is also predicted withpassenger numbers forecast to double or triple by 2050. Achieving drastic reductions in the emissions from gas turbines,without bring national economic activity to a standstill, requires urgent activity on a very wide number of fronts. This isparticularly important for the UK. It has Europe's largest gas turbine industry, second only to the US, including majorengine makers, such as Rolls-Royce, Alstom and Siemens, together with approximately 3,000 companies supplyingalloys, high integrity components, such as discs, blades and shafts, as well as coatings and seals. The industry as awhole employs over 400,000 people and generates 2 billion in exports in the power sector alone.The aim of this programme is to meet this challenge by identifying and developing materials based on refractory metals,such as Mo and Co alloys, while carrying out shorter term research to extend the usefulness of Ni-based alloys. Thework will involve a coordinated programme of materials development and processing, microstructural and defectmodelling, characterisation and prediction of these high temperature materials designed to answer the fundamentalquestions that will enable their potential to be fully realised.To generate a critical mass of researchers, the programme brings together academics from 6 universities with expertise inthe necessary areas, together with Rolls-Royce plc to ensure the research is appropriate and to establish a route forexploitation.The success of the UK high-value engineering sector is an area in which improved public understanding is needed toimprove the perception of metallurgical engineering generally and to engender enthusiasm to encourage more youngpeople into science and engineering. To address this, a significant programme of public engagement has been designedto run alongside this research programme
