Circa 10,000rpm at 1050mph?

Jeez!

Likely to underspeed slightly on acceleration & overspeed slightly on deceleration due to the inertia & rate of change of velocity of the car.

See i understand everyone of those words when said individually, but in that sentence it is causing me confusion.

I read it as they (the wheels) will be slipping when accelerating/braking.
So for every 2835mm (ish) the car travels under acceleration it will actually be slightly less than a full turn of the wheel due to the thrust being rocket/jet propelled rather than wheel driven?
And when braking as the brake forces will mostly be drag based for every 2835mm (ish) that the car travels the wheels will actually turn slightly more than one full rotation?


Can someone with a better trained brain tell me if i have that right?

That's it in a nutshell yes. Due to inertia

:woo:

I have remembered some basic physics.

I must confess i thought it sounded really stupid until i remembered that the wheels weren't providing the power.

What is the centrifugal force on the rim at 1052mph?

I could spend the time working it out but I have had some wine, and I am sure it has already been calculated by the team?

Roughly 50000g.

NO NO NO, you've got it all wrong.

The standard way of telling somebody the g acting on the rim is.


"Fifty THOUSAND radial g"

Dad?




Actually, is there info on what the wheels are capable of structurally?
At what point would they disintigrate?

Try to imagine that it's on a conveyor belt

Between 15750 & 16800rpm

I want to see the video of that test

Won't be happening.

The carbon discs made enough of a mess when they burst. Brian was handed a dustpan & brush by the rig owners & told to go & clear that f*****g mess up.

Can i see the video of that test then?

Ladies & gentlemen, delivered today......one of the fastest wheels in the world.......

You should have said. A mate of mine is a croupier and can get ready painted ones pretty cheap. Do you need...ahem...dice as well??

Some pictures of our reduction gearbox that lived between the Cosworth engine & the HTP pump.

Is that basically a very big shiny paper weight now?

I'll take that off your hands, I'm sure I can find a use for it.
How about a fiver?

[Silver Smudger]

Is there a replacement for that V8 yet?
