The research project aims to, in collaboration with Airbus UK, investigate the complex dynamic interactions between the flexible aircraft dynamics, its aerodynamics, the flight control system, and the atmospheric environment. This is an essential feature of aircraft design to, at its best, ensure a smooth ride in turbulent wind and, at its worst, prevent structural failure. However, interaction with the atmospheric conditions is a particularly challenging computational problem that has historically been addressed using rather conservative processes by the civil transport aircraft industry. Ambitious efficiency targets to achieve net-zero aviation are driving the aircraft designs towards higher-aspect-ratio and, therefore, more flexible wings. Such a design ambition demands new analysis methods and processes, as well as innovative wing architectures. We will investigate strategies to multi-point design of the outer wings, which are likely to include movable mechanisms in most future long-range civil aircraft. This project comprises the development, comparison, and validation of numerical methods for the analysis of aircraft with very high aspect ratio wings, which is the most aerodynamically efficient strategy, but one that is also highly sensitivity to the atmospheric conditions. This comes with a major computational overhead and a compromise is needed to be found between simulation accuracy and computational efficiency. This project will investigate novel computational methods to address that challenge, to be implemented as part of the Imperial Load Control and Aeroelastics Lab-led open-source multiphysics toolbox SHARPy, as a stepping stone towards a design framework for greener and more efficient aircraft.

该研究项目旨在与英国空中客车公司合作，研究柔性飞机动力学，空气动力学，飞行控制系统和大气环境之间的复杂动态相互作用。这是飞机设计的一个基本特征，在最好的情况下，确保在湍流风中平稳飞行，在最坏的情况下，防止结构故障。然而，与大气条件的相互作用是一个特别具有挑战性的计算问题，历史上一直由民用运输飞机工业使用相当保守的过程来解决。实现净零航空的雄心勃勃的效率目标正在推动飞机设计向更高的展弦比和更灵活的机翼发展。这样的设计目标需要新的分析方法和流程，以及创新的机翼结构。我们将研究外翼的多点设计策略，这可能包括未来大多数远程民用飞机的活动机构。该项目包括开发、比较和验证用于分析具有非常大展弦比机翼的飞机的数值方法，这是最有效的空气动力学策略，但对大气条件也非常敏感。这带来了主要的计算开销，并且需要在模拟精度和计算效率之间找到折衷。该项目将研究新的计算方法来应对这一挑战，作为帝国载荷控制和气动弹性实验室领导的开源多物理工具箱SHARPy的一部分，作为迈向更环保，更高效飞机设计框架的垫脚石。
