[PTA SC] Thrust SSC @ 763 MPH

De OP
A Stanley Steamer first reached 150 miles an hour in 1907. Since then, top ground speeds have doubled every thirty years, but only a handful of people have experienced those top speeds.

ThrustSSC Speeds got stuck just below the speed of sound in the early 1990s. The British, who took the record away from the American Breedlove in 1983, finally went supersonic in 1997. They did it in their ThrustSSC, with its driver's pod hunkered down between two huge turbojet engines. By now it's reached 763 miles an hour.

The biggest problem the British faced was determining how shock waves would interact with the ground. At supersonic speeds, wind forces can blow a car about like tissue in a hurricane. If the car's the least bit unstable, the driver is a dead man.

You can't test such behavior in a wind tunnel, because you'd need a road moving past the stationary test vehicle at more than the speed of sound. Only in the last few years have supercomputers reached the capacity for making such complex airflow calculations. Only recently has it become possible to design such a car.

And there lies a great irony. The nuclear test ban treaty has given Los Alamos Laboratory a major impetus for developing such complex computations. They hope to reach the point where they can model nuclear blasts. By banning live tests, the treaty might well be contributing to the design of nuclear weapons, at the same time it's stimulating the development of new tools for racecar makers.

In any case, the British car went supersonic just fifty years and a day after Chuck Jaeger did it in an airplane. Then, on October 15, 1997, at Black Rock, Nevada, RAF squadron leader Andy Green pushed the car to Mach 1.02 (763 miles an hour) with his wheels turning at 8500 rpm. And he lived tell of it.

Thrust SSC is powered by two Rolls-Royce Spey jet engines, as used in the RAF and Royal Navy's Phantom fighter-bomber aircraft. Testing of the car is performed using two Spey Mk202s, while record runs utilise a more powerful hybrid Mk202 - often called a Mk205 - version of the engine.
