1000mph car to be powered by rubber and hair-dye. Answered
The largest rocket fired in the UK for two decades will be lit soon, in the race to produce a land-vehicle capable of 1000mph.
It will burn a mixture of solid propellant (HTPB, or hydroxyl-terminated polybutadiene, a kind of rubber) and liquid oxidiser (high-test peroxide, HTP, a highly concentrated form of hair-bleach) for 20 seconds.
The Bloodhound SSC will also be powered by a jet engine from a Typhoon fighter.
In the 20 second burn, the rocket will need fed with a tonne of HTP, so the pump is being powered by a Cosworth Formula 1 engine, which will become the only piston-engine running in a car at supersonic speed. The team are planning to give the engine a major power-boost by feeding the supersonic airstream into the engine without slowing it to the usual operating speeds.
The huge engineering challenges are being used to inspire students through the UK's STEM programme.
