This partnership between the University of Nottingham, Rolls-Royce, Imperial College London and the University of Oxford will undertake research in order to advance six key areas of mechanical engineering science which will enable Rolls-Royce in particular (and the UK more generally) to remain at the forefront of aircraft propulsion throughout the transition to all-electric flight. Across all modes of transport, the twin challenges of climate change and decreasing fossil fuel reserves has resulted in a concerted effort to find alternatives to traditional internal combustion engine technology. In transport sectors such as rail and automotive these challenges are increasingly being addressed through the introduction of new electric vehicle technologies which is revolutionising the market through new technologies, new market entries and new business models. Several estimates indicate that within 15 years the majority of new cars will be either all-electric or electric-hybrids with range extenders. The aerospace sector faces much greater challenges in moving towards low carbon propulsion, due in large part to the greater distances that must be covered between refuelling opportunities and the fact that battery technology has not yet developed significantly enough to address the challenges of long range travel. There is however a clear recognition across the aerospace industry that a transition to all-electric flight is both desirable and essential to the future of human mobility. Rolls-Royce recently announced their commitment to a long-term future business model underpinned by hybrid-electric and all-electric flight and this partnership will undertake some of the critical, underpinning research which will enable this step-change. In order to meet the roadmaps set out by the Aerospace Growth Partnership and the Advisory Council for Aviation Research and Innovation in Europe dramatic progress must be made in a number of technology areas in order to achieve a transition to all-electric flight. CornerStone will advance six areas of mechanical engineering science: 1. High power-density contacts2. Impact and Intelligent Failure Management3. Advanced Static & Dynamic Load Management4. Exploiting Aero-structural Interactions5. Innovations in Thermal Management6. Electro-Mechanical InteractionsThe underpinning scientific developments and their integration into aerospace engine applications will equip Rolls-Royce to lead the global aerospace industry in the journey up to and including all-electric flight. Cornerstone will enable Rolls-Royce and subsequently other UK machine manufacturers to achieve a step-change increase in the value of their products and to shift the proportion of added-value away from pure manufacturing towards intelligent design.

诺丁汉大学、劳斯莱斯、伦敦帝国理工学院和牛津大学之间的合作伙伴关系将开展研究，以推进机械工程科学的六个关键领域，特别是使劳斯莱斯（以及英国）在向全电动飞行过渡的过程中保持在飞机推进的最前沿。在所有运输方式中，气候变化和化石燃料储量减少的双重挑战促使人们共同努力寻找传统内燃机技术的替代品。在铁路和汽车等运输行业，这些挑战越来越多地通过引入新的电动汽车技术来解决，这些技术通过新技术，新市场进入和新的商业模式彻底改变了市场。一些估计表明，在15年内，大多数新的汽车将是全电动或电动混合动力与范围扩展。航空航天部门在迈向低碳推进方面面临着更大的挑战，这在很大程度上是由于加油机会之间必须覆盖更长的距离，以及电池技术尚未显著发展到足以应对长途旅行的挑战。然而，整个航空航天业都清楚地认识到，向全电动飞行的过渡对人类移动的未来既可取又必要。罗尔斯·罗伊斯最近宣布，他们致力于以混合动力和全电动飞行为基础的长期未来商业模式，这一合作伙伴关系将进行一些关键的基础研究，从而实现这一转变。为了实现航空航天增长伙伴关系和欧洲航空研究与创新咨询理事会制定的路线图，必须在一些技术领域取得重大进展，以实现向全电动飞行的过渡。基石将推进机械工程科学的六个领域：1。高功率密度触点2.影响和智能故障管理3.高级静态和动态负载管理4.利用航空结构相互作用5.热管理创新6.基础科学发展及其与航空发动机应用的整合将使罗尔斯·罗伊斯能够在全电动飞行的旅程中引领全球航空航天业。基石将使劳斯莱斯和随后的其他英国机械制造商能够实现其产品价值的阶梯式增长，并将附加值的比例从纯制造转向智能设计。
