Bloodhound – The 's Rear Lift Problem Fixed
The car's aerodynamic shape produced dangerous amounts of lift at the vehicle's rear. The research team members have at last found solutions to fix the problem.
"We're very close to fixing the exterior aero surface, which really opens the floodgates to the rest of the design work to get going," said John Piper, the Technical Director.
By playing with the position and shape of key elements of the car's rear end, the design team has now found the best way to manage the shockwave passing around and under the vehicle as it goes supersonic.
Bloodhound's aero shape is yet, not completely fixed. Further work is still required on the jet intake ducts, the winglets that control lift, the air brakes (deployable structures that slow the car) and the large rear fin.
The team also needs to model the air flow into the car. However, the team can now push forward on the main chassis structure and interior packaging of all the components that go into the vehicle.
The solution is a major milestone in Bloodhound's design. To claim the world land speed record, Bloodhound will have to better the mark of 763mph (1,228km/h) set by the Thrust SuperSonic Car in 1997. It will be powered by a combination of a hybrid rocket and a jet engine from a Eurofighter-Typhoon.
