Do you guys only make bits out of huge slabs of Ali! The ali honeycomb we used on satellites has a skin thickness of 0.2mm. And they go faster than 1000mph!!
For the next car they are going to install a 30 mile perfectly frictionless surface and remove the earths atmosphere, this will reduce the load on the car quite a lot Dave Hedgehog said:

For the short time this vehicle is exposed to the elements, I would've thought that WD40 or similar would suffice for corrosion protection.
My undestanding is that galvanic corrosion doesn't have much to do with being exposed to the elements anyway. It's caused by the metals reacting with each other like a battery pile - hence the jointing compound to keep them separate.CraigyMc said:

That was the type of corrosion I was referring to.I have used both the barrier cream stuff and physical barriers (plastic tape) to seperate dissimilar metals, but was wondering if the SSC team had some super-duper aerospace technology, or what their plan was.

I believe that WD40 was 'invented' for NASA
I'd never heard this before but did a google and if wikipedia is to be believed it pre-dates NASA and was "developed to prevent corrosion in nuclear missiles" and was first used "to protect the outer skin, and more importantly, the paper thin "balloon tanks" of the Atlas missile from rust and corrosion".AstonZagato said:
Sorry but an idiot question.
At those speeds, wouldn't a tail rudder make more sense?
At a guess, to break the land speed record for a car it has to meet certain build criteria. A rudder would make it steer from the rear, which as anything much over 10mph is, interesting. Also the wheels on one axle would still have to steer or be like casters or the rudder wouldn't make it change direction. Probably. At those speeds, wouldn't a tail rudder make more sense?

At above 400mph the front wheel actually act as rudders.At those speeds, wouldn't a tail rudder make more sense?

Think about what you've just said there & get back to me. Hint:- consider the loads, the thickness of the atmosphere, the fact that pretty much everything will have chunks of desert thrown at it by the wheels.https://www.youtube.com/watch?v=XQD6qedj5Q4
