The Car Faster Than a Speeding Bullet
pbahra writes "Formula 1 is seen as the apogee of engineering excellence and automotive power. So it says something that in Bloodhound SSC — the car that, if all goes well, in 2013 will shatter the current land speed record — the Cosworth Formula 1 engine is just the fuel pump. 'We are creating the ultimate car; we're going where no-one has gone before,' said Richard Noble, the project director. The car, which Mr. Noble says takes £10,000 a day just to keep it ticking over, will be powered by not one, but two other engines. The smaller one, the EJ200, is normally found in the British Royal Air Force's Typhoon jet. Its job is to get the 13.4 meter long car up to 350 mph. That's when the big one kicks in. The big one is the 18-inch diameter, 12-foot-long Falcon rocket, the largest of its kind ever made in the UK. Its job is to catapult the car through the sound barrier to its maximum speed of 1,050 mph. That is, literally, faster than a speeding bullet."
The real challenge is not getting a vehicle to go that speed... It's getting a vehicle to stay on the ground and under control at that speed.
Moderating "-1, Disagree" is simple censorship. Have the guts to post your opinion.
1050 MPH? Thats not very fast for a bullet.
Well, maybe it is fairly good for a pistol.
But it is about half the speed of a 5.56mm NATO round from an M-16.
People like you are why socialism doesn't work.
I've had enough abrasive sigs. Kittens are cute and fuzzy.
I took a tire off my car and dropped it on the ground. Suddenly the Earth had a wheel. Now the Earth is not only the largest car, but also the fastest -- going around the Sun at 67,000 mph....
But what useful knowledge would we gain from this experiment?
I mean, we get supersonic vehicle to stay on the ground at speeds where it would most definitely rather fly. It's not all that useful. We develop air drag model and shape for a vehicle which has no practical purpose, nor ever will. We spend lots of money and resources just to develop a variant of a jet plane we forcibly keep from flying, for no good reason but to call it a "car" and beat a "ground" speed record.
I still say it''s a waste: the little we can actually learn from this could be either learned using vastly less resources, or the resources could be used to learn something vastly more useful.

Also of interest, is the Australian Competitor. The "Aussie Invader" team is attempting to beat the Brits, while using a fraction of the budget.
That's a good use our our civilization's precious natural resources.
Well that's kind of who we are as a civilization. We climb mountains because they are there. We landed on the moon, half because we wanted to challenge ourselves (and half to show our economic system was better than communism...).
It's a general feature of life to use resources like mad without thinking long-term until the resource is nearly depleted and we have no choice. Natural selection really grilled that lesson in deep before it gave us brains smart enough to begin to question it.
I hate to be the one to say it, but this does seem utterly pointless.
Not in the "we should be spending money on hospitals" sense, but rather "all you're doing is taking a rocket and trying to cripple its flying tendencies". There are so many more cool inspire-the-kids (which is the nominal point) projects they could do! Here are some crazier and more cool ideas I just had:
* A manned quadrocopter.
* A massive computer-controlled Archimedes mirror.
* An Asimov-style multi-speed travelator.
* A Back to the Future hover-board using active magnetic levitation.
Those would all be way more awesome than "Oh its a rocket with wheels attached". /rant.
I guess that is a rather modest proposal....
General Relativity: Space-time tells matter where to go; Matter tells space-time what shape to be.
I've just been scrolling through some of the comments above. "Why bother?" "Spend money on hospitals!" "What are we going to learn from this?" "This isn't really a car because the power isn't going through the wheels." "Waste of money!" "There are cooler projects to spend money on!"
You know what? Get over yourselves!
Every time I see a cool story posted on /. I find myself bracing for the impact of a squillion know-it-all comments about how useless it is from the usual armchair "I call bullshit" merchants who think they have all the answers to all the world's problems. Oftentimes it's American commenters from the "not invented here" lobby who want to pull a World Cup defence and say "Well it's a bullshit competition anyway so we don't care if we get whipped!" Grow the fuck up! The Brits have made the land speed record their own and I for one tip my hat to them. It's a great way to inspire kids to get involved in engineering, just like your toy with the heavy wings and expensive heat shield up there at the minute.
So the UK government is pushing a sponsorship-funded R&D project that doesn't have immediate commercial payoff. Big deal! What would you prefer to spend the money on? Another day in Iraq?
Jesus wept! Can we not have a story posted on here anymore without having to wade through all this obnoxious crap?
Oh, and I have karma to burn, so knock yourself out if you don't like a bit of straight talking.
Drill baby drill - on Mars
Strictly speaking, the F1 engine is actually the oxidiser pump for the hybrid rocket engine - it runs the peroxide pump.

I know someone who is involved in the Bloodhound project, working with a large education company over here (one of the sponsors of the car). There is a really big focus on the education side of things with this; they're touring schools and colleges doing presentations, along with a full size replica of the car. One of the big reasons for doing it is to get kids at school interested in science, maths and engineering and that seems like a pretty good idea because there has been a continuing decline in students going on to study those subjects at higher levels in the UK (and I believe most Western countries these days).
There's a bit about it on their website http://www.bloodhoundssc.com/education.cfm . I also doubt that the overall resource usage for the entire project is actually that high (I'd bet fewer resources used than most Hollywood films for instance), so if it increases interest in the areas they're targeting so that general science and engineering gets a bit more attention, I don't think that's too bad a result.
.
The decades of high-speed train engineering has involved reducing drag wherever possible. Infact some future concepts are looking at running maglev trains through vacuum tubes as the only possible way to reduce drag further and close the gap between train and aircraft fuel efficiency.
So no, I can't see a single benefit this gas-guzzling rocket-propelled coffin will have for Bullet trains.
It's their money, their hobby, their time. It's nobody else's business.
Infuriate left and right
I, for one, am glad I live in a world where the practical dominates my day-to-day, but the fantastical is occasionally made reality.
Get your head out of your bank acocunt balance, and enjoy the dream... Especially since you're not writing the checks, and the dream looks like a fun one.
