The Bloodhound is a supersonic car. The car is driven by jet engines to break the 1000-mile per hour mark and become the second car to reach supersonic velocities. When the car reaches the end of the track, a breaking parachute is deployed.
The environment of the parachute is quite challenging as not only the velocity is high, but the density is high as well. This combination means that the dynamic pressure is high.
At a velocity of 1300 km/h, the car uses airbrakes to decelerate. Airbrakes are deployable flap-like structures that create drag. When the car reaches about 965 km/h the parachute deploys slowing the vehicle down to velocities where the regular disk breaks can take over.
