Uni closes in on a 1,000mph car.

Byline: Robin Turner Reporter robin.turner@walesonline.co.uk

HAVE you ever wanted to know what would happen if you travelled in a car going at 1,000mph? If so, Swansea University may be the place to go.

Experts at the seafront campus working on the Bloodhound SSC - supersonic car - have published a paper of the aerodynmic characteristics of travelling at 1,000mph. Scientists from the university's college of engineering are part of the British team developing a car capable of reaching 1,000mph (1,610kmh), which is faster than a handgun bullet.

Powered by a rocket bolted to a EuroghterTyphoon jet engine, the vehicle will mount an assault on the world landspeed record. Bloodhound will be run in trials at speeds on Hakskeen Pan in Northern Cape, South Africa, in 2015 before making the record attempt there in 2016.

e Swansea University paper has been published in the Journal of Automobile Engineering.

It is based on simulations by the Walesbased engineering experts who have looked at how the car will cope with the challenge of rolling over ground at 1,000mph and the resulting shock which will be thrown up.

Dr Ben Evans, a key member of the Bloodhound team and one of the authors of the paper, said: "In order for a ground vehicle to travel at over 1,000mph (approximately Mach 1.3), the team has created the most advanced fusion of space, aeronautical and Formula 1 engineering ever attempted. "Clearly, the aerodynamic challenges associated with developing a land-based vehicle capable of safely travelling at transonic speeds are great.

"Drag minimisation and vertical aerodynamic force control are of paramount importance for a safe record attempt on the constrained distance of 12 miles available at the record attempt site in Hakskeen Pan, South Africa. "Computational uid dynamics (CFD) has been chosen as the primary tool to guide the aerodynamic design of the vehicle."

" On working on the project, Dr Evans said: ese computational models have already inuenced signicant design aspects of Bloodhound, including the front wheel conguration, the shape of the nose, the jet engine intake shaping, rear wheel fairings and wing shape and size.

"It is also evident there are still questions to be answered regarding the accuracy of the model, such as exactly how the shock waves will interact with the ground surface at Hakskeen Pan, particularly if the shock waves cause the surface to break up."

Development of the Bloodhound began in 2008 and was aimed at breaking the 763mph landspeed record set in 1997 in Nevada.

A fullscale replica of the 40ft car was rst unveiled at the Farnborough Air Show in July 2010.
