I suggest the Dec issue will firmly settle these debates... and result in some interesting r&d projects.There are have been endless debates on what exotic gas Ferrari could be using. There were even reports that they may be using Argon, but the gas is just too exotic. Helium might also be a good candidate.
It's a probably bit much to be filling all your tyres with at every race and every test unless there was some serious advantage to it - that's the point - although it is reasonably available via industrial processes. A more general purpose gas would be more suitable. However, it does have some interesting properties, such as low thermal conductivity.flynfrog wrote:i can buy a bottle of argon down the street for welding its neither rare nor expensive
When we have new tyres fitted they are overinflated by the tyre company. (in our championships this is usually Avon / B.M.T.R.) to around twenty five p.s.i. then delivered to us where they are then reduced to our desired pressures.Militia Est Vita wrote:But I heard somewhere once (I think a Discovery channel Williams F1 dvd that I bought for 5 bucks) that Bridgestone or Michellin (back in the Michellin days) inflates tires for the teams and then they deliver the tires for the teams, is that incorrect? Or if it is not, does teams have specifications on what or how should Bridgeston set up their tires before they are delivered to the team? Or is it just now that teams receive the rubber and they are in charge of the whole process.
Have to agree really. There are only so many combinations, and of course, there is the possibility that what Ferrari is doing is not so spectacular after all. There's not much suspense in it at all.Ciro Pabón wrote:As for my attention span, I hardly can keep myself commited to a subject for a week; you, trying to keep the suspense until December is inhuman. If you know, nobody else does, and you don't post, well... why I am thinking this is taking unfair advantage of the forum?
Ok let's try brainstorming. According to Wikipedia "Brainstorming is a group creativity technique designed to generate a large number of ideas for the solution to a problem." We have the prerequisite group with creativity to spare.ss_collins wrote:Its so obvious once you know
Now that COULD actually have a devastating effect on performance especially if the gases weighed far different amountsMilitia Est Vita wrote:A more technical question then would be if tyres can be inflated with a mixture of 2 different gases? I'm no chemist but maybe density of 2 gases inside 1 single tire would have disastrous effects on tyres?
And also:The permeation rates of hydrogen, oxygen and nitrogen in rubber on a vacuum (you really can find anything on the Web) are 2.2, 2.0 and 0.53 (all expressed in 10^-8 square cm/sec). This means than on a rubber container, oxygen is 4 times more prone to diffusion than nytrogen and helium is just marginally (10%) harder to contain than oxygen. This is an approximation, as I understand that this is measured with vacuum at the other "side" of the rubber being tested.[/b]
Finally, I don't know why I have been forced to say twice that air is a mixture of gases. Nobody seems terrified by filling his tires with air..."Reca pointed out in a different thread that air density is 0.0012 g/cm3, a tenth of what I used. Thus, the weight of air in all the tires is a mere 840 grams. This gaves you very little mass advantage and a really small lift if you substitute for helium, then"
