Successful Engine Test in UK For Planned 1000 mph Car
amkkhan writes with this excerpt from International Science Times: "Scientists aiming to create a car that can break 1,000 mph cleared a large hurdle yesterday when they successfully tested their rocket engine. The engine will power the supersonic car known as the Bloodhound SSC — meant to become the fastest car in the world. The British team tested the engine in an aircraft shelter in Newquay Cornwall Airport, originally designed to protect fighter planes from bombs. Although the data hasn't fully been analyzed, the researchers said the engine reached 30,000 horsepower during the 10-second burn. Given enough time, they expect the engine to reach 80,000 horsepower and 27,500 pounds of thrust."
I just got my old girl primered and re-upholstered and I'm thinking a new engine would really make her kick ass. I got $200 and and '86 Silverado (that just needs a new transmission) that I'm willing to part with, if you're interested in selling the engine after you break that record.
What political party do you join when you don't like Bible-thumpers *or* hippies?
I used to think this kind of stuff was pretty amazing. It certainly used to be amazing for a car to go hundreds of miles an hour. Now I think it's getting to the realms of stupidity. It's pretty likely that more people are going to die doing this stuff, but for what?
I think this type of research would be better directed towards getting planes to go faster, not cars. There is probably a lot of overlap though, since basically all of the challenge here will be the aerodynamics.
Alternatively, doing the same challenge without allowing rockets would be damn cool. I just don't get the point of rocket cars.
which is totally what she said
The rocket is the EASY part. What we need to know is, how is work on the Oscillation Overthruster going?
Sweet, this'll make my commute sound* awesome.
* but I'll still be stuck in a traffic jam
On a more serious note, I guess it's pretty neat that they've designed a rocket that runs along the ground without taking off or digging itself into a crater, but what does it really prove in the end? It's just a record speed. Oh well, it's there to be done I guess, and that's a good reason.
Did anyone else read that as MPG? I read the whole summary and was like "REALY??!!!!?!?!!?!?!!" Anyway, this is a 2-stage car that uses a jet engine to get past 200MPH-ish and then a rocket engine to get to 1000+. That really is the right way to do it, as rocket dragsters on drag strips tend to steer badly due to slight takeoff jumps and pushes in a direction other than straight.

Why would you classify a rocket engine in horsepower? Thrust is really what you're after, though even peak thrust is a bit of a useless measure. An overall or maximum total impulse would have been a nice touch. Bonus if they'd use a standard, like N-s, as their unit.
Is it just my observation, or are there way too many stupid people in the world?

...but if you assume constant acceleration over the 42 seconds to get to 1000 mph (~447m/s), it will take a distance of around 9.4km to reach top speed. That's a long drag strip.
No. A wheel-driven car hasn't held the land speed record since 1965, when Blue Flame (a rocket car) beat Bluebird's record, though the most recent recordholders are jets rather than rockets.
Incidentally, the some of the same guys who made Blue Flame are the ones behind this vehicle.
upon the advice of my lawyer, i have no sig at this time
A rocket with wheels is still just a rocket, doesn't matter where its aimed.
Pedantic, but we are among geeks - a rocket engine gives *NO* horsepower in a static test, because there is no work being done. The power is a product of the thrust and the speed times some constant to get it in the desired units. No speed = no power.
They claim to get 80,000 hp at 1000 mph - that's about 30,000 lbs of thrust, which is reasonably consistent with the claimed final thrust. They could have just said that.

I'm all for cool science projects but at those speeds I think we can assume any accident will be fatal, especially if the fuel ignites. Why not partner with the google team to make it autonomous, it would be great press for google and would generate buzz for the project.
When a vehicle's primary means of forward momentum is no longer via the transmission of energy to the ground through wheels but instead via high speed ejection of gasses through a jet exhaust, it should no longer be considered a car. It's a rocket sled.
I never saw the point of building Thrust SSC and its ilk.
Can the technology be transferred to street legal cars? No. Does it provide new insights into the science invlved, such as aerodynamics? No, since they use mostly existing rocket science (pun intended) to make it work. How does a project like this advances science?
Oh well, at least it's privately funded, so we can rest assured our tax money isn't being pissed in the wind.
If a fighter jet touches its wheels to the ground, is it a car?
~7.75×10^10 (furlongs/(fortnight^2))
All things considered, I'd rather have a 1000mpg car than a 1000mph car.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
They don't mention enough to calculate the acceleration.
In metric, a furlong per square fortnight is: 1.375*10^-10 m/s^2 so I guess the value we're looking at would be several gigafurlongs per square fortnight at least though.
keep the FUCK AWAY FROM IT!!! that is all :P
...or do all these land speed records seem to boil down to just how fast you can scrape a de-winged jet aircraft along the ground?
"Dance like nobody's watching"
I've got plenty of karma so I'm just going to say it.
I've just been scrolling through the "what's the point" posts and all I can say is get the fuck over yourselves. If this thing were built in America you'd be calling it the greatest thing since the outside toilet. Same as how you pissed on Concorde, one of the greatest technical achievements of the 20th century, after you didn't get your act together with your own SST projects. Same s how you defend your suckiness at soccer by claiming "oh but we don't care about that game anyway."
But you know what? The Brits have made the land speed record their thing. I say good on them and I have to ask what ground-breaking records have you broken from the comfort of your mother's basement lately?
Lighten up, you depressing fucks!
Drill baby drill - on Mars
I thought people across the pond use kph not mph when dealing with speed. If not then let me know what I'm missing. All I learn of that part of the world is from Doctor Who shows so sorry if I'm a bit confused. Although I do like the fish and chips not fish sticks and pudding.

For that we hand it over to our tame racing driver.
Some say that He toasts hot dogs backwards, and that given half a chance he too would put a ten thousand horsepower engine into a lawnmower.
All we know is, he's called the Stig.
All this talk about "breaking" the speed barrier and how fast this car goes with not one sentance devoted anywhere to how this thing stops reminds me of an earlier darwin award involving JATOs.
At 1050 MPH if course is perfectly flat at same alt you have between 6 to 15 seconds depending on height of obstruction to change course after any object can even be detected by any sort of optics over the horizon.
Don't forget to factor in stone per rood and quid cubed.
Look back up at my post, now look back down, you're on the Internet. Now look back up. I'm a signature.
Google tells us that
((30 000 horsepower) / (27 500 pounds force)) * (10 seconds) = 1.8 kilometers
Unless that's a BIG aircraft shelter, they probably didn't get 30K HP out of the engine.
My guess is they bolted it to a static test stand, where it generated exactly 0 HP.
Compare
(1.21 gigawatts) / (88 miles per hour) = 30 757 874 newtons
Yea sounds about right.
Standard course at Bonneville for high speed runs is something like 6 miles to accelerate, 1 mile for the timed portion (the speed quoted for the record is the AVERAGE speed over this mile), and then several miles to stop.
TODO: Something witty here...
It uses coffee!
Won't that cause blindness in the driver?
Andy Green, ex-RAF pilot and the holder of the supersonic land speed record as driver of Thrust SSC is the chosen driver for the 1000mph Bloodhound. He also holds the world land speed record for a diesel-powered wheel-driven car, the JCB Dieselmax which took the record to 350mph at Bonneville in 2006.
Sounds more like a horizontal rocket to me.
The engine isn't the problem. There are many aircraft engines powerful enough. The problem is keeping the "car" stably in contact with the ground. Really, anything going that fast is an aircraft. The aerodynamic forces dominate.
Finding a long enough flat area to run the thing is getting hard. The Bonneville Salt Flats aren't big enough any more. The last few land speed record efforts moved to Black Rock Desert, and this one is planned for the Hakskeen Pan dry lake bed in South Africa.
Rails work better than salt flats. Holloman USAF Base has a 10-mile high speed test rail track for rocket sled tests. The speed record there is 6,481 MPH.
Wow, a 1000 mpg engine? Cool!
Oh, wait, you mean more horsepower.
Here's a news flash, guys, if it can't get 100 mpg nobody's going to buy it.

It was Craig Breedlove's Spirit of America in 1963 if you count 3-wheel vehicles. Otherwise, it was Breedlove's second Spirit of America (Sonic 1) in 1965. Blue Flame was later.
When you put wheels on a cruise missile and replace the warhead with a cockpit, it becomes a car.
Quit trying to be funny. You aren't. You are just stupid.

Yeah, I got my dates crossed. Blue Flame set the record in 1970.

If it has a rocket engine it's not a car. It's a ballistic device with a (hopefully) flat trajectory and just happens to have wheels.

THANK GOD!!!
As professor Irwin Corey, world's foremost authority, might have said; "Scientists know best- never trust science to engineers and mechanics."
And so we have Scientists designing rocket cars. Why? Well apparently they majored in Rocket Science, a course offered only at the prestigious Brighton School of Rocket Science and Hard Knocks.
To add even more prestige to the stunning development of this unique rocket car, respected Science publisher iScienceTimes has consented to publish an abstract of the work to date. You will recall some of their recent work: ...

It must be different in the US, but here in the UK "JCB" is pretty much the standard shorthand for what you call a back hoe. So this presents a somewhat humourous image to a British mind.
To have a right to do a thing is not at all the same as to be right in doing it
The Dieselmax and its record campaign was paid for by JCB, based around their new (at the time) JCB 444 diesel engine they had designed for back actuators, front-loaders etc. They were heavily tweaked of course with the two engines in the car eventually producing about 1500hp in total for the record runs.
Interestingly the diesel-powered car record was one of the longer-standing entries in the FIA record books with the previous holder's record being set in 1973 at a bit over 230mph.
