## Cockpit Revealed For Bloodhound Supersonic Car81

Zothecula writes: Unveiled at a special event in Bristol, U.K., the Bloodhound land speed team showed off the cockpit that will be driver Andy Green's "office" for his record attempt run in 2015 and 2016. Although Green holds the current world land speed record of 763 mph (1,227 km/h), the challenges in attempting to break the 1,000 mph (1,600 km/h) barrier will be significant for both pilot and the design team.

There are strict rules and regulations for the land speed record and they are met by this vehicle. If you disagree, come up with a new record committee with new rules and see if people want to set a record for that.

Not a rail guy by any stretch of the imagination, but I was always under the impression that the units in a train, maglev or conventional, were called "carriages". Based on this assumption, "cars" would be an abbreviation of this that has fallen into colloquial usage, rather than a formally "correct" term for them.

As stated though, that's just the impression I was under, so I could be miles off-base here...

Indeed, there has been much controversy surrounding these attempts since at least the 60's.

The FIM however was more than happy to classify it as a motorcycle (http://en.wikipedia.org/wiki/Spirit_of_America_(automobile)).

The comment on not using aerodynamic down force is rather telling. Only reason I can think of for not doing so is that if they did, it would consume power that could otherwise be used for more speed. And since motive power isn't being supplied through the wheels, traction isn't all that important. I do wonder if steering will be entirely via the wheels, or if they're using aerodynamic means.

Racing cars try to dump down force when they don't need it - ie in straights and high speed corners. Down force is good for traction in low to medium speed corners, but it becomes a huge hindrance elsewhere. McLaren pioneered stalling the rear wing of their 2010 F1 car along the straights, giving them a couple of dozen extra MPH over their rivals, which makes all the difference when you are trying to pass them. This was later adopted by the FIA and became the Drag Reduction System.

When the goal is "go fast in a straight line", a parallel goal is "eliminate drag", of which down force is a huge component.

I think the comment is better interpreted as "we want some downforce, but not so much that it crushes the front suspension." I suppose ideally you would have zero downforce on the wheels, so that you have essentially zero rolling resistance. But as a practical matter you need to have some for stability. better to have some than risk having none, or negative (airborne!). Plus, if the wheels aren't actually in contact with the ground, it c

The reason is explained in the video - when you're traveling at that speed, the loads you put through the suspension are huge. You don't want to have the suspension compressed before hand or it'll just break.

Wouldn't it be awesome to put wheels on a Saturn 5 first stage? Even an SRB would be cool.

Then again, I wouldn't think as much of it as a wheel driven car.

Years ago at a drag strip, they had some races between two jet cars, one with a transmission, and one with afterburner and jet only propulsion. The races were pretty even, the main difference was the almost quarter mile line of rubber laid by the transmissioned car.

No one has stopped doing wheel driven land speed cars. This is just a different class. If you want wheel driven, you can look to those classes and there is still plenty of partisipation. However, the wall of air encountered by a wheel driven car causes traction issues (imagine trying to accelerate pressed up against a birck wall) and at some point (I think it is around 400-500 MPH) the wheels just start spinning. it is not an issue of power. Power is easy to come by these days. The traction is the problem, especially on poor surfaces like salf flats. I agree it would be impressive to see these traction issues overcome, but it has been an issue since the ''60s and I don't see a solution in sight. Do you?

It may well be one solid piece of carbon fibre with a 2 cm thick windscreen and a front struct that can take 30 tons of force , but it wouldn't make any difference if it was made out of reinforced unobtanium - if he looses it and has a rollover at 1000mph he's dead. Even if the structure survives - which I doubt - the G forces will probably kill him anyway.
