Fluid-structural interactions in high-speed flows. This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters.

The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field. This coupling can result in damage or even catastrophic structural failure and thus robust design tools must be developed to avoid this.Read moreRead less
Fluid-thermal-structural interactions on high-speed aerospace vehicles. Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems.

Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing. This project will design and perform first-of-kind experiments that reproduce the complex fluid-thermal-structural interactions representative of those experienced by these aircraft and rockets. We will then use these measurements to assess, validate and improve the current state-of-the-art of simulation and modelling approaches for design.Read moreRead less

The aim of this research is to develop a framework for multiple Unmanned Aerial Vehicles (UAV), that balances information sharing, exploration, localization, mapping, and other planning objectives thus allowing a team of UAVs to navigate in complex environments in time critical situations. This project expects to generate new knowledge in UAV navigation using an innovative approach by combining Simultaneous Localization and Mapping (SLAM) algorithms with Partially Observable Markov Decision Processes (POMDP) and Deep Reinforcement learning. This should provide significant benefits, such as more responsive search and rescue inside collapsed buildings or underground mines, as well as fast target detection and mapping under the tree canopy.

This study aims to exploit an innovative physics-based approach to predict the strength of textile composites. This is particularly important in areas such as aircraft design, where drastic weight savings are needed to allow designers to remain competitive in a low-carbon future. Improved theory and design tools will remove conservatism and account for a large part of these weight savings. The new approach is the first to be consistent at all length scales — from atoms to aeroplanes — ensuring relevance for new and evolving composite material systems. A novel understanding of crack initiation in textile laminates is intended to reduce design and certification effort for new aircraft and help to design more efficient airframes at a lower cost.Read moreRead less
