The Challenge
Swansea University’s Computational Fluid Dynamics team was asked by the Bloodhound Land Speed Record project to create an aerodynamic shape capable of safely reaching 1000mph on land.
We are enhancing aerodynamic design
Led by Professor Ben Evans, Swansea University’s Computational Fluid Dynamics (CFD) team played a key role in the aerodynamic design of the BLOODHOUND Supersonic Car, building on expertise developed during the THRUST Supersonic Car project.
The team applied advanced modelling techniques and proven methodologies, using FLITE - the same computational system previously employed in the design of THRUST SSC - to conduct highly detailed simulations of airflow and overall vehicle performance.
FLITE enabled accurate modelling of the interaction between the moving vehicle and the ground, a critical factor at supersonic speeds. This capability significantly reduced simulation times, allowing complex aerospace analyses to be completed overnight rather than taking several months.
Through these simulations, the team developed computational models of the aerodynamic flows experienced by BLOODHOUND. These models were used iteratively to test, refine, and optimise the vehicle’s design.
The Impact
- The computational aerodynamics design system FLITE had a direct and substantial influence on BLOODHOUND’s final design. Key aerodynamic features shaped by this work included the configuration of the front wheels, the shape of the nose, the jet engine intake design, the rear wheel fairings, and the size and form of the wings. As a result, the CFD team significantly improved the vehicle’s aerodynamic performance and efficiency.
- The FLITE system was instrumental in the success of the THRUST SSC project, which set a World Land Speed Record in 1997 by becoming the first car to break the sound barrier. Building on this legacy, BLOODHOUND was designed to safely achieve speeds of up to 1000 mph - approximately five times faster than a Formula 1 car.
- The project has contributed to substantial public engagement in science and engineering. The use of FLITE and the wider BLOODHOUND programme supported a large-scale education initiative, engaging more than 5,000 schools and inspiring interest in STEM subjects among young people.
