Successful Engine Test in UK For Planned 1000 mph Car 262

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.

        Firebirds of that era were front engine. I think Pontiac made anything but the Fiero with front engine and the Fiero is a frightening drive with the engine it had (I whipped out a few times in mine and it always spun around with the rear of the car going in the direction of travel. Couldn't sell that thing fast enough.)

      This project is being used to get kids interested in science, technology, and mathematics. That's why it's being partly-funded by the government, including the loan of some Typhoon engines. It's not just rich guys going "what what" and driving like idiots - they actually put some thought into it. They tour the car model around schools and get the kids to make projects based on it. The car is also not a rocket car, but a rocket/jet hybrid. It has a rocket engine (which uses a Formula-1 car as the oxidiser pump - that in itself is pretty cool), strapped to one of the engines from a Eurofighter jet (the aforementioned Typhoon engine). It's a really fascinating project.

          But far more boring to most kids. I admit, it sounds pretty boring to me too, even if it is the more responsible goal to aim for. The UK has a problem with getting kids interested in the STEM (Science, Technology, Engineering, Maths). Most kids love explosions, fire, noise and power. You lecture them on how you can make a car go 1000 miles on a gallon of fuel, and most would probably fall asleep.

          This however, is fast, noisy, pushes science/engineering to its limits, and shoots a massive jet of fire out the back, what's not to love? It gets kids excited, which is its primary goal, it is an excellent world showcase for the high-technology design/manufacturing that the UK still has, and installs some pride in the UK populace. It is not a blueprint for all future cars, so the fact it gets 0.04mpg (uk gallons) is irrelevant, especially as it will probably only run a few times in its life.

          Not to fret though, there are lots of challenges every year to see who can get the best mpg (I think we're up to 350mpg on diesel). Different strokes for different folks and all that. There is a lot of work on both sides of the fence :)

          But for a twelve year old kid, there's just something about the idea of strapping yourself to a missile for no other reason than to go really, really, really fast. Turns are great, and I agree, but come on - 1,000 mph? I'd do it, and I'm a full-grown human. Now imagine being a little kid and seeing this thing tearing ass across the desert.

        • There's little practical purpose in being able to go over 200mph in a car though, given current roads

          Given that you're on an island 200 miles across, I'm going to strongly agree with that...and some of us Americans also enjoy cars that can turn both left AND right.

          • Which is why we don't like to buy cars made in our own country. Maybe in some distant future our automotive engineers will discover the magical secrets of turning. Until then we just have to stick to European and (occassionally) Japanese cars.

            • I hate to break it to you, but American cars have gotten a lot better at turning in the last decade or two, at least compared with the run-of-the mill Japanese cars. I've rented a bunch of different cars over the last years, and the American cars like the Chrysler 200, Ford Fusion, and Chevy Impala had handling just as good as the Mitsubishi Galant and Nissan Altima and Toyota Corolla I drove (which is to say, they were all competent for 4-door sedans but were pretty sloppy IMO).

    • Planes already went fast. Supersonic passanger jet technology was introduced long ago. The difficult part is making it financially viable in the current economy - Concorde just cost too much to run.

      The focus of civilian aviation now isn't on speed, but cost - finding new ways to make the planes ever more economical to operate, either by increasing fuel efficiency (Fuel being a major cost) or to cram more paying passangers onboard to reduce the per-passanger cost.

          Actually, they're not. Boats are much more efficient for cargo, but a fast boat from the UK to the USA takes over a week. That means that you need to take enough food for a week, have enough space to keep people entertained for a week, have people employed to clean the cabins en voyage and so on. Your passengers also have to be able to spare a week or two each way for the journey. Boats are fine for short trips, although loading and unloading can quickly become a bottleneck, which drives up the cost because harbour space is a finite resource.
    • In order for a 1,000 mph car to be approved for driving/testing by a human, i would imagine the funding agencies would require all kinds of safety gear. if, through the development of new safety tech brings us some new breakthrough that scales down/back and makes 80 mph crashes much safer, isn't that a worthwhile pursuit?

      If you want to see a raw speed challenge that uses a number of reciprocating piston engines you should go check out speed week [scta-bni.org] at the Bonneville Salt Flats [wikipedia.org]. I don't know how many rocket or jet vehicles compete but there are a number of regular vehicles (cars, trucks, motorcycles) and a ton of categories to compete in.

    • I have to agree, this project is a total waste of time. It's really nothing more than sticking an aircraft engine in a car. We have lots of places that can go faster than 1000 mph; we've been building mach 2+ planes for decades now. The SR-71 could go Mach 3 IIRC, and that was built in the late 50s or early 60s. There's no point in making a "car" that goes that fast, when you can only do it at the Bonneville Salt Flats, and it has zero practical application. It's not like we can make passenger cars go

  • 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.
  • ...of the Decade in 5, 4, 3, 2...
  • 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.

    • Horsepower lets us visualize 80,000 horses and the manure that they produce. Now, since each of the 80,000 horses is limited in speed, you still have to figure out how to put them in series to get the desired 1,000 mph (they can't pull but they could push), but, still, it's important to some to think of the problem in this way.

    • Yes, came to post this. I'd say a requirement of a "car" is that it is propelled solely through torquing the wheels. This is effectively a (steerable?) rocket sled.

      • Alternatively, the requirement could be constant contact with the ground. Most objects will fly at 1,000 mph; I know the takeoff speed of my Corolla is around 120 mph.

    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.

    • Pedantic, but we are among geeks - a rocket engine gives *NO* horsepower in a static test, because there is no work being done.

      Well, it is accelerating its fuel and oxidizer to a great speed out the back. We seldom think of a rocket as a big gas cannon that just happens to have a lot of recoil, but it wouldn't be incorrect.

    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.

Keep up the good work! But please don't ask me to help.
