Policy makers and regulatory bodies are demanding the aerospace industry reduces CO2 emission by 50% and NOx emission by 80% by 2020. In order to meet these drastic demands and ensure affordable air travel in the future, it is essential to make lighter aircraft which will use minimum fuel. The aerospace research community recognises the need to make a dramatic performance improvement and is considering several new aircraft concepts that move away from the conventional two-wing-one-fuselage configuration. This brings new challenges to aircraft design. A wing is a highly complex structure to design as it needs to consider the complex interaction between aerodynamics and structural behaviour. The current design practice is therefore very much based on using the previous successful design data. The challenge of departing from the conventional aircraft is that there are limited successful historical design data that is applicable to new concept aircraft. Once we have a wing design, however, there are sophisticated computational methods that analyse how the wing behaves under external flight conditions.In fact, there has been a significant level of development in computational analysis methods taking advantage of growing computational power. A prime example of this is the recent development in the computational modelling of materials. Using this technology, new advanced materials can be created in half the time that traditional material development takes and the return on investment in computational materials research has been estimated at between 300 - 900%.This fellowship is at the heart of developing sophisticated computational methods to design aircraft configurations that have not been considered before. The majority of the current methods analyse how a given material or structure responds to the external environment such as in flight at speed Mach 0.8, 38000 ft. What is different about the methods in this research is that they are inverse of the analysis methods: They will determine the best combination of advanced material and structural configuration based on the external environment and hence design the optimum wing for the given flight conditions. My research approach is to represent the design problem as a set of mathematical functions and develop computational methods to find the optimum solution. The methods will therefore, find the optimum design for both materials and structural configuration at the same time. The outcome of this fellowship will provide engineers with a sophisticated tool to design complex aircraft structures. The tools will be developed and disseminated in a way that they can be used on a range of other complex engineering problems.The UK has 17% of the global aerospace market share with revenue of £24 billion and is responsible for 3.6% national employment. With the international civil aerospace market forecast to grow to $4 trillion by 2030, the UK market has the opportunity to grow to $352 billion by 2030. It is critical that the UK develops this unique capability to ensure we maintain the market share of these high value products and processes and its economy has the opportunity for growth. Furthermore, the weight savings which will be made from optimum use of materials lead to meeting the emission targets, thus ensuring sustainable environment for the future generations.

政策制定者和监管机构要求航空航天行业在2020年将CO2排放量减少50％，NOX排放量减少了80％。为了满足这些急需的需求并确保将来负担得起的航空旅行，必须制造使用最小燃料的较轻的飞机。航空航天研究界认识到有必要改善性能，并正在考虑几个新的飞机概念，这些概念摆脱了传统的两翼一号婚姻配置。这给飞机设计带来了新的挑战。机翼是设计高度复杂的结构，因为它需要考虑空气动力学和结构行为之间的复杂相互作用。因此，当前的设计实践非常基于使用先前的成功设计数据。偏离常规飞机的挑战是，适用于新概念飞机的成功历史设计数据有限。但是，一旦有了机翼设计，就有复杂的计算方法可以分析机翼在外部飞行条件下的行为。一个主要的例子是材料计算建模的最新发展。使用这项技术，可以在传统材料开发所需的一半时间内创建新的高级材料，并且计算材料研究的投资回报率在300-900％之间。这项奖学金是开发先进的计算方法来设计以前未考虑的飞机配置的核心。当前的大多数方法分析了给定材料或结构如何响应外部环境，例如以0.8，38000英尺的速度飞行。这项研究中的方法有什么不同之处在于，它们与分析方法相反：它们将确定基于外部环境的高级材料和结构配置的最佳组合。我的研究方法是将设计问题表示为一组数学功能，并开发计算方法以找到最佳解决方案。因此，该方法将同时找到材料和结构配置的最佳设计。该奖学金的结果将为工程师提供设计复杂飞机结构的复杂工具。这些工具将以一种可以在其他一系列复杂的工程问题上使用的方式开发和传播。英国拥有全球航空航天市场份额的17％，收入为240亿英镑，并负责3.6％的国家就业。到2030年，随着国际民航市场的预测将增长到4万亿美元，到2030年，英国市场有机会增长到3520亿美元。至关重要的是，至关重要的是，至关重要的是，这种独特的能力至关重要，以确保我们维持这些高价值产品和流程的市场份额，并且其经济能够实现增长的机会。此外，可以通过最佳使用材料节省的重量节省，从而实现了排放目标，从而确保了子孙后代的可持续环境。
