Flex in non-flexible wings

Ah , but the flex in the nose seems to be canting the wing down , causing the extra flex in the wing at the ends , due to the extra angle and resultant pressure , so indeed the curvature would , presumably , be changing .

The real magic here , seems to be the fact that at both extremes and everywhere in between , the car is stable , and creating a good bit more downforce than the others when they need it .

The question is , are they prompting the change , or do the aeros just work like that at various speeds ?

You don't need different top and bottom surfaces to generate lift (or downforce). A symmetrical cross-section wing will do so depending on the angle of attack. Aerobatic planes have symmetrical profile wings, and can generate equal amounts of lift both right way up and upside down by adjusting their angle of attack.

I think almost certainly it's purely controlled by the aerodynamic forces. If there were some actuating mechanism then they'd risk someone spotting the connection during nosecone changes.

There is a similar thread running over at 10 tenths.. A forumer stated Re- Autosport mag "there was an interesting full-page article about this 2-3 issues back. Apparently RB put a big pile of cash into researching the construction of more-flexible composites 3 years ago, with last years car being the first beneficiary of the technology"

Anyone on here subscribe to the mag?

I tried to find it but instead came up with a link to ATL a specialist in flexable composites used for various technologies from UAV's to fuel cells, interesting entry in the news section...

"Congratulations to Red Bull Racing!

Thursday, 16th Decemberr 2010

ATL would like to extend its congratulations to Red Bull Racing claiming the 2010 F1 constructors championship and to Sebastian Vettel for becoming 2010 F1 World Champion"

Not wanting to read to much into it but could they be flexable composite development customers other than just simply customers of an FIA aproved fuel cell?.

Re- Horners comments about the rake angle.. defo telling part truth imo... if he had mentioned the words flexable nose and dynamic rake angle.. it would be bang on the money.

Seb will always be on top, sorry.

Yes, he is quicker than his team mate but what does that have to do with this thread?

Maclaren is very close or perhaps for now faster than the Bulls with their flex wing. It´s the driver that makes the differece, Seb is better than Lewsi and Button.

Ross Brawn's take on this:

"Their wing probably gets tested more than anyone else's. I think there are two developments that will come - either the tests change or more people will move in that direction because it brings greater efficiency. That is where it is.

"They pass the test and those are the tests that decree whether the car is legal or not. But we see quite honestly there is another car out there that is not using that approach that is quite competitive as well, so it is not the only solution."

"Shall I explain in very basic words how it works?" he asked.

"McLaren have developed a car that has a very low rear-ride height, and therefore a low front wing for them doesn't work.

"We run quite a high rake angle in our car. So inevitably when the rear of the car is higher, the front of the car is going to be lower to the ground.

"It is obvious science, and therefore our wing complies fully with the regulations. It will look lower to the ground because the rake in the car is higher, but it is simple mathematics."

"I think our front wing has been tested more than any other in the pit lane, and it complies with the regulations, which is what we have to do. We don't have to pass a McLaren test, we have to pass an FIA one, and it complies fully with that.
