I think it'll get to 1,000 mph easily with a big turbo on it.
Er, a jet engine has a bloody great big fan thing at the front, I think you'll find it's called the compression stage. i.e. a Turbo (sort off) !!!I wasn't actually serious though, I think for the short runs this has planned then nitrous would make more sense.

When you see the footage and data traces, it's very apparent that the car was on the ragged edge and there wasn't much left in the tank in terms of stability.
There absolutely wasn't with Thrust SSC - I seem to remember that there was an unrealised 5mph margin before catastrophic instability, they'd only missed it by fluke!dfen5 said:
What I don’t get about this, is why put someone in it? All the risk, space and life support requirements when a laptop would do a better job and no body if it goes wrong.
Anyway, ditch the bodged up looking ‘200mph tested’ jet dinosaur, shrink it, railgun tech.
To qualify for the LSR the car must have 4 wheels and a driver who must be in full control of the vehicle.Anyway, ditch the bodged up looking ‘200mph tested’ jet dinosaur, shrink it, railgun tech.

Be better off setting a land speed goal for an EV. Certainly more relevant in today’s world.
Can’t help but feel the project team/sponsors realised this and pulled the plug on this environmental terrorist.
Or they got fed up of wheeling it in and out of Mach shows..

Thank goodness the world has switched to electric airliners, electric rockets, electric helicopters, electric fighter planes. Racing fans are so much better off watching Nascar, IndyCar, F1, Drag racing, etc, now that they switched to electric power.Be better off setting a land speed goal for an EV.

Sarcastic yes, but the above is not ever going to happen. Sure, electric will have its niches, but it will not replace many of the facets of vehicles I named above

I might be misremembering, but I thought it was Thrust 2 that was that close to the edge.
SSC had, for example, the ability to jack up the rear wheels to increase downforce, I think, so was aerodynamically OK.

In the end they abandoned the adjustable rear wheel scheme and ran it with the wheels in a fixed position, fully extended IIRC to give the car a nose-down attitude.SSC had, for example, the ability to jack up the rear wheels to increase downforce, I think, so was aerodynamically OK.
I also remember Green, I think, said that the final extra run they did with SSC was really pushing it and with hindsight, wouldn't (or shouldn't) have done it.

SSC had active suspension that would adjust the rake of the car above a certain speed to alter the attitude. The trouble was that it was almost too effective, and the car tried to plough its way into the desert when it was used in the abort run position (IIRC it would automatically kick in between 350-400mph, but it could be forced on command). A halfway house measure was used on the record runs to adjust the rake, but handling wise it was on the ragged edge. By that point it was bursting rivets and tearing panels off each and every run.

Thrust 2 had its own stability issues, but the reverse; rather than the front end digging into the ground too much, it was on the cusp of flipping over backwards had it gone perhaps 10mph faster. In both cases, the cars were on their respective limits of stability. Staggering to watch, but at those speeds it would have been ugly had they gone much quicker.

I think you're right. Even with the perennial faffer Noble moved aside, I fail to see how sponsors are going to invest in something that's not really been of interest for several decades.Be better off setting a land speed goal for an EV. Certainly more relevant in today’s world.

Regarding the environmental terrorist comment, the defenders will argue it produces less CO2 during its lifetime that one lactating cow in a year, etc. but it's the perception and what it represents that's wrong. Pop this dinosaur in a museum alongside Noble's other unfinished projects and move on to modern world challenges instead!

They switched off the active suspension. The car tried to bury itself at 500 mph, they switched it back on.I also remember Green, I think, said that the final extra run they did with SSC was really pushing it and with hindsight, wouldn't (or shouldn't) have done it.

Not quite. The panels behind the engines were bonded on, due to the discovery that rivets wouldn’t stand up to the heat and acoustic battering they were subjected to. I helped to develop the structural adhesives which were used. They were a modified version of a product which had been available for many years ( namely the ‘shear resistance’ and cured thermal stability specs had to be improved) which we managed with a lot of effort. There was an operator error issue with the preparation of one of the panels used on one run ( the surfaces weren’t etched properly before the adhesives were applied, and the panels were attatched) This resulted in one section detaching itself, and damaging the parachute. It only happened once, and we did find the cause fairly quickly. So basically Andy was driving a damaged car with greatly compromised braking abilities, at over 400 mph at one point

Its very sad when people stop pushing the boundaries of science in any direction. Yes the world is arguably moving on, but I'm sure the Bloodhound team are making discoveries in some fields which can then be applied to other things as well.

And it'll be very very sad when people stop doing things, simply because they're cool and interesting.

The awesome thing about a project like this, is that what you think or feel, or how much you put down others, does not affect the project....you are not involved. If you think the entire transportation system of the world is going electric, or will revert to Horse and buggy days, you are mistaken.
