Rocket/jet car for breaking 1000mph




"RAF fighter pilot Andy Green intends to get behind the wheel of a car that is capable of reaching 1,000mph (1,609km/h). Powered by a rocket bolted to a Eurofighter-Typhoon jet engine, the Bloodhound car will mount an assault on the land speed record."

These are all fascinating attempts. The risk of catastrophic failure is very high, particularly by damage to the wheels or instability of trajectory. Readers may remember my previous post with the rocket powered bike. Rockets are able to send large objects to just about any speed, far greater than 1000 mph, but there are other complications. In order to go much faster (or indeed slower under most instances), the rocket must become a rocket sled. The challenge of guidance and stability are just too great at high speed. A person could reliably be sent to mach 3 on a rocket sled, if only a sled range long enough were constructed to maintain safe G loads accelerating and decelerating.
