Sorry but an idiot question.

At those speeds, wouldn't a tail rudder make more sense?

Trial fit of the rack too.....







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

That's what I like. Thinking out of the box!! Incidentally, the military vehicles I worked were made of bloody strong unobtanium!!! Horses for course eh ?

Do you have any corrosion concerns, with all the dissimilar metals in contact?
I know it won't be parked outdoors over winter, but still, steel + aluminium + titanium : do you get surface corrosion at the interfaces?

kind of assume they would be using something like this:



it's kind of essential on cars like the Elise where you have steel brackets onto an Ali chassis.

What stereo is going in and, more importantly, are you going to install a banging subwoofer?

For the short time this vehicle is exposed to the elements, I would've thought that WD40 or similar would suffice for corrosion protection.

Don't forget the air freshener, nodding dog and a packet of gum.

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.

My understanding of it too.

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.

In terms of absolute "Loudness" i suspect the solid rocket motor will do a good enough job of "banging" out the tunes! ;-)

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".

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.

I could be wrong but I think rear wheel steer is quite common on LSR cars. I believe the Thrust SSC steered from the rear. I am sure there will be a logical reason too but I don't know what it would be.

Yeah, Thrust SSC steered from the rear, they had a Mini rigged up as a proof of concept - I think that is at Coventry Transport Museum along with Thrust SSC.

At above 400mph the front wheel actually act as rudders.

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.
