Sonic Wind
this was a land speed record vehicle that would have run on ice. i was thinkin that wudnt the shockwave from the sonic boom break the ice?

i guess that would depend on how thick the ice was!

As the vehicle breaks the sound barrier the pressure wave will actually form behind it. As it goes faster the pressure wave would fall farther and farther behind. Theoretically the vehicle would outrun the destruction occuring in its wake.

I'm getting the picture that this isn't going to be the ideal family runabout?

As the vehicle slows to below the sound barrier the destruction (if it were occurring) with drop and off and the vehicle could coast down to a sane speed on the ice.
Problem is, where do you find a ice sheet long enough to get a car up to speed that is smooth enough. A large frozen lake is going to be rough and have heaves and such in it, unlike the Bonneville Salt Flats which are faily smooth. Unless someone has a fleet of Zamboni's to go out and shape the ice I doubt there is a smooth enough and large enough ice field to run on. |

It's moon Triton might be a better bet as Neptune itself is mainly Hydrogen

I thought for a minute there you said Titan, the well known moon of Saturn. That wouldn't do because it's lakes are full of mercury.
It would, however, be a good place to set up a executive desk-toy and thermometer factory. |

(more off topic: Europa, a moon of Jupiter, is renowned for having a very smooth surface. The crust it is made of ice and consequently is relatively bright as it reflects a lot of sunlight.) Actually this is quite interesting. graham bahr is right in that it depends on the thickness. KC shows that that it probably isn't a problem because it happens behind you - well not an issue until the return run!  Stopping? Well that could be a problem, although a parachute would be just as effective on ice as it doens't depend on the grip of the wheels. I would guess that the brakes aren't good on LSR cars anyway - do the wheels have good grip? I would have thought that the friction is kept to a minimum here, especially now that the ultimate record is not by a wheel driven machine. Last edited by Adam43; 25 Mar 2004 at 13:27. |

I read that the SSC car was literally pummelling the ground as if went over it, that the front wheels were going much slower than the rears.
Also the main engineer had some very serious worries about what the shock wave was actually doing. And no matter how fast you go, the edge of the wave is always going to start at the nose, hence lifting the car slightly on ice, sand or anything else. This Sonic Wind car was gonna be rocket powered aswell I think, so would have been very small and light compared to the jet cars |
