The Bloodhound Project is a world land speed record attempt that is moving closer to reaching its goal of building a supersonic automobile.
The Bloodhound Education Programme, aiming to inspire young people to pursue careers in science, technology, engineering and mathematics, has been working on the car for years, and the design is just now moving out of the computer models. Engineers have recently unveiled a 1:1 scale model replica which was on display this week at the Farnborough International Airshow in Hampshire, England.

The Bloodhound aerodynamic team, lead by Ron Ayers, generated millions of mathematical equations to investigate how the air around the 12.8-meter-long car would react as the vehicle accelerates to its maximum design speed of 1,050 mph, and using this information they designed an efficient shape that would be stable at supersonic speeds while still offering control at a sub-sonic velocity.

Metallic structures manufacturer Hampson Industries built the primary rear structure of the supersonic car from a combination of steel, titanium and aluminum.

The rear structure is of critical importance to the design, as it needs to be capable of handling 9 tons of jet thrust from the EJ200 engine, plus 12 tons of thrust from its Falcon hybrid rocket. Vibration and high temperature from both the jet and rocket, along with the suspension loads and the 9 tons of brake chute drag, put great stresses on the body at supersonic speeds.

Bloodhound SSC will reach supersonic speeds of more than 1,000 mph. At these speeds, in just one hundredth of a second, this car will travel 10 feet. To the left is the EJ200 jet engine.

The vehicle will carry 963 kg (2,100 lbs) of HTP, supplied to the chamber by a high speed pump, which is based on the large HTP pump used in the Stentor rocket engine that powered the U.K.'s Blue Steel cruise missiles in the 1960s.
