The British 1000 mph Car Project: Bloodhound SSC — Designing The Fastest Wheels in History


Bloodhound SSC is a British supersonic land vehicle currently in development. Its goal is to match or exceed 1,000 miles per hour (1,609 km/h) achieving a new world land speed record. The pencil-shaped car, powered by a jet engine and a rocket engine is designed to reach 1,050 miles per hour (1,690 km/h). It is being developed and built with the intention of breaking the land speed record by 33%, the largest ever margin.

Runway testing of up to 200 miles per hour (320 km/h) occurred on the 26th, 28th and 30th of October 2017 in Newquay, Cornwall. Bloodhound SSC will then be tested on the Hakskeen Pan in the Mier area of the Northern Cape, South Africa where a track 12 miles (19 km) long, 2 miles (3.2 km) wide has been cleared.

In July 2016, it was reported that Andy Green will attempt to break his own World Land Speed Record with Bloodhound (to 800 mph) in October 2017. In March 2017 this attempt was pushed back to summer 2018.

The equation is a=(w^2)*r where a is the acceleration, w is the angular velocity and r is the radius.
First we must convert RPM to radians per second. There is 2(pi) radians per revolution and 60 seconds in a minute. So 10,000 RPM equals (10000*2(pi))/60, which rounds to 1047. We then simply enter these values into the equation. For our first calculation on space station v we get a=(1047)^2*0.455=498,775 m/s^2
Acceleration due to gravity equals 9.8 m/s^2, so if we divide our answer by that we can see that it is 50,895 times the acceleration due to gravity.
