OT - Chris Harris on 1000mph Land-Speed Record Car...

Jashley73 · Mar 3, 2015

Disclaimer, this video is 42min long, but is worth every second as it's some of the best Engineering-porn I've seen in quite some time...

For those not familiar, Chris Harris is a British motoring-journalist, with a really entertaining YouTube channel where he reviews all sorts of exotic sports cars. This time, he takes on the Bloodhound SSC a land-speed record vehicle under construction, in an attempt to break 1000mph on land.

It uses a jet-engine from a Euro-Fighter jet aircraft, a hybrid-fuel rocket, and a supercharged Jaguar V8, just to drive a hydrogen-peroxide pump... - around 135,000 estimated horsepower...

What a cool video. Enjoy...

Oh wow. Thankyou for sharing this.

I was still in college when Andy Green and Craig Breedlove were simultaneously trying for Mach 1...

We used to run out of class and bolt to the nearest student dump housing with cable to catch the live updates on Speedvision.... Remember speedvision?!

That was good fun!

I've never thought about going up in an aerobatic plane as a thing I'd like to do, but I think that's on my list now!

If it's a one time interest, you can probably find a flight school, even somewhat local to you, that does initial basic aerobatic training in something like a Citabria or maybe Cessna 152; or possibly even a Pitts or Walter. The smaller airplanes will be cheaper. They should give a good basic ground school (hour or so) of what you plan to do and expect, and whether that suits your interest or any concerns you have. Then plan a flight with 15 minutes to 1/2 hr max to start. In fact, you might do best with an intitial 20 minutes to 1/2hr introductory flight (non-aerobatic) first where they treat you as a student and you basically fly the airplane under the instructor's control and guidance except for the landing. After that experience percolates in your sensory centers for a couple days or week, then go back for the intro to aerobatics. You'll get a whole lot more out of the experience than feeling like you where thrown in a washing machine on spin-dry with a glass window. And the early maneuvers should not really be high G. Just enough for rolls which after an initial demonstration, the instructor might even guide you through doing yourself (raise the nose x°, now bang the stick over to the stop

) Stall/spin/recovery, a couple inside loops. Inverted flight for a bit if you are ok with it. Hesitation roll. Maybe a hammerhead stall, as in the video.

I'm not in any way gonna suggest you climb in an airplane behind the first guy who offers to take you up for aerobatics. For one thing, to be legal in the US, you both need parachutes. The flight training school would be compliant with all that. They also tend to have a program worked out to comfortably "thrill" the initiate, not scare the bejabbers out of them. But if aviation holds a bigger interest than a one time ride, a good place to start is to find a local EAA chapter. The point of the organization is to make aviation accessible. We love new members with enthusiasm. Some chapters have a very active building program. Many have routine options for flights (go for the proverbial breakfast fly-in or $100 hamburger on Saturday morning, so might as well take a passenger/budding copilot along). Some, like ours, have the most economical means possible to get a pilot license through club owned aircraft and member instructors.

Pretty impressive for a country that has always made complete garbage cars.

Here's a link to a build thread....pretty long, but lots of cool pictures.
Bloodhound SSC Thread As Requested..... - PistonHeads
Really like to know the total cost of this thing when it's done.

Always taking the piss eh?

Give 'em some leeway- their dreary, perpetually moist climate doesn't lend itself to preserving vehicular electrical systems.

Awesome video. The fuel pump motor for the rocket engine is a dry-sump supercharged Jaguar V8!

This vehicle sounds like an excellent way to get yourself instantly ground into slime on the Bonneville salt flats,which are bad on skin!

the car and the engines are not what interest me but the wheels are. Just what does it take to make a wheels that will hold together, hold a load and control the vehicle at 1,000 MPH?

There is a YouTube video on how they made the wheels. They're solid forged aluminum. Spin at 10k rpm.

John,do you mean complete shit cars like Rolls Royce,Bentley,Aston Martin?

Mercedes overtook Rolls a while back. But I now hear that they have slipped in quality and are not so reliable.

I take it that they have TIRES that will take those RPM'S too? Guess they must.

The Brits and Italians know how to make a good looking car shaped object

No tires on it for the actual runs. They have some for some "low speed " testing.
I think the plan is to start making early runs by this fall, going to use some
place in South Africa, I think.
Lots of info and cool pictures in the build thread.

seems like we already put the brits in the barrel within the last month . . . http://www.practicalmachinist.com/v...-1000-mph-bloodhound-ssc-build-thread-298719/

No time to watch the vid now but I'm intetested in watching it!

gwilson · Mar 4, 2015

We Americans made some pretty bad cars until the Japanese forced us to compete.

stephen thomas · Mar 4, 2015

The whole concept is bizarre and practically pointless.
All it really is, is an exercise in keeping a rocket, which was originally designed to fly, from doing so, without attaching it to a rail.
So I suppose that fine point makes it a car? Even without a transmission/wheel drive?

Oh, well. Maybe there will be something further learned about compressibility or sonic issues for High Speed rail applications.

Thanks for the detailed response!

I've always found flying and aerospace engineering to be fascinating, wanted to be a fighter pilot when I was a kid but I have a dodgy eye that ended that particular dream fairly early on.

Going to a flight school as a way of getting a taste seems like a really good idea! I won't be able to look into that in the near term because of other commitments, but I'll definitely keep it in mind! If I could get in the air in a Mustang that would be a dream come true I can tell you!

Check out Stallion 51 Stallion 51 - P-51 Mustang Flight Ops

They have dual cockpit / dual control P-51's for instruction
