Integration of nonlinear aeroelastics effects in the industrial loads and aeroelastic process

该研究项目旨在与空客英国公司合作，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复杂的动态相互作用。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，历史上一直是由民用运输飞机工业使用相当保守的过程来解决的。实现净零排放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发展，从而使机翼更加灵活。这样的设计野心需要新的分析方法和流程，以及创新的机翼架构。我们将研究在未来的远程民用飞机中可能包含可移动机构的外翼的多点设计策略。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，这是最具空气动力学效率的策略，但对大气条件也高度敏感。这带来了很大的计算开销，并且需要在模拟精度和计算效率之间找到折衷方案。该项目将研究新的计算方法来解决这一挑战，并作为帝国载荷控制和气动弹性实验室领导的开源多物理场工具箱SHARPy的一部分实施，作为迈向更环保、更高效飞机设计框架的跳板。

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.
