Back-yard speed record attempt aims for 2,000mph

Californian engineer reckons he can double Bloodhound SSC's 1,000mph ambitions



If your New Year's resolutions amount to nothing more ambitious than a half-hearted attempt to cut down on the booze, then perhaps you should look to Californian Waldo Stakes, whose Sonic Wind project aims to break the 2,000mph barrier. We kid you not.

And the quite astonishing thing about the project is that, unlike the British Bloodhound SSC project, which has soaked up millions of pounds and is being created by a dedicated team of engineers and other brainy types, Sonic Wind is a one-man operation.

Super-fast X-15 provides motive power...

One man who, for the record, quit formal education at the age of 19 and whose workshop does not even contain a computer.

Now, it would be easy to dismiss Stakes as a crackpot with a snowball's chance in hell of getting his project off the ground. But that would be a cheap shot, and does not take into account two things: one, he already has speed-record form with both bikes and cars and two, he happens to own a pair of XLR99 rocket engines.

These were developed for NASA's X-15 experimental plane, which still holds the fastest speed ever reached by a manned rocket-powered aircraft (4,519mph). In addition to the 57,000lb-thrust rocket (which out-thrusts Bloodhound by a good 10,000lb), Stakes also owns a pair of fuel tanks from a Redstone rocket.

...to take on British Bloodhound project

It's a good basis, sure, but unfortunately that, along with a heap of designs and a 1.2-metre model, is really all that so far exists of what will hopefully become a 15-metre seven-wheel monster.

Mr Stakes, we salute your passion for speed.

He probably ought to do a little reading on air resistance and friction before he starts

From what I recall, a lot of Breedlove's designs were finger in the air gut instinct rather than loads of aerodynamic simulations.

Worked for him up till he tried to beat SSC then had stability issues.

Good luck to him, good to make it a competition!

Question 1.
What does a Home Built rocket car + 57,000 lbs of thrust make?

Is the answer A. 2000MPH land speed record, or B. Rather rapid end to a mans life?

He needs to read the January edition of Racecar Engineering for a start. Nearly half the magazine is dedicated to the current LSR projects and why they are all struggling with it before they even hit the ground.

totally agree! bloodhound has 4 times the power of thrust ssc just to go an extra few hundred miles an hour! I suspect this project will fail very fast indeed!

I fear it may be 'B'.

Thrust SSC was a case in point. SSC was designed via endless computer simulations to see how it would behave in the trans-sonic region (sort of Mach 0.9 - 1.3 from memory, but don't quote me on that). They then verified these findings with tests on a rocket sled. As mentioned above, and to quote Breedlove, SofA Sonic Arrow was 'basically designed by eye'. As a result it lifted a wheel about 15 ft at 675 mph.

I fear with the speeds now being talked about and the physical forces acting on the car, the days of the garagista with a big engine may be numbered.

As I understand it, to double the speed, you need to quadruple the power, as the wind resistance is a squared, therefore 4 times as much.

(Assuming the same shape, etc.)

Since he isn't getting four times the power, he's going to have to do some seriously tricky stuff with the shape of the machine, which I suspect will affect the stability somewhat.

It will be interesting to see what happens. I applaud his efforts too. There doesn't seem to have been as much "pushing the limits of what is possible" in my lifetime, so well done to him.

Colour me "interested, impressed, but sceptical."

My working out is on the back of a fag packet, so may be wrong. Like the guy we're talking about.

I FOR ONE CAN'T WAIT TO SEE THIS.
OTHER QUESTIONS TO BE ANSWERED WILL BE

AT WHAT SPEED WILL HE TAKE OFF ?
WHAAT ALTITUDE WILL HE REACH?
AT WHAT POINT WILL HE DIE ?

ITS A SHAME HE DOESN'T HAVE A COUPLE OF SPARE SPACE SHUTTLE SOLID FUEL ROCKETS HANGING AROUND.
HE COULD PROBABLY GO FOR 5000MPH THEN ( HE SPEED TERMINATED WHEN HE PLOUGHS INTO THE BLACKROCK MOUNTAINS LOL

Something I don't understand about big-number land-speed record attempts is how wheels and tyres cope with the sorts of rotational speeds involved.

The bodywork, aerodynamics and power are easy, right? All this knowledge exists in aviation engineering, but wheel-speeds of 1,000+mph is uncharted territory.

Doogz - bloodhound ssc is a rocket hybrid

Also, Mr Gear, you could argue the knowledge doesn't exist in the aviation industrym as for planes the shockwaves at this speed have all the space they need to disipate around the plane. The ground rather gets in the way of this with a car, so not an awful lot is known in all reality. Only computer simulation and what was learned from Thrust
