What are these bits circled ?

It's a vent, though I don't know what for. Some have said it's cockpit cooling.

They were there all last year, but I think this is the first photo on which they've shown up this year. I think the Merc has the same thing.

What about rifling in the exhaust tailpipes to "spin" the exhaust in a certain direction? I've read the Regs & see nothing specific saying you cannot.

http://en.wikipedia.org/wiki/Rifling

Gonna need more than rifling to spin the air coming out of a 3" pipe. You see the rifling in guns look like they spin the bullet by touching it in flight. To spin a body of air, you will need some turning vanes...

Maybe take one row of this..but a bit less aggressive an angle.

Out of fuel?

Last minute of the last day at Barca is a thoughtful time to do an empty tank test, which I suspect it was.

to add spin to the exhausts you ould mix them with flow form radiators making the lattere join in transverse direction. From the test pictures it seems mclaren are doing somthing like that on the 4-27

This has been discussed before - ATM_andy informed us that it's to measure ride height and slip angle. In other photos you can see a cable going across the nose.

Mp4-27 exhaust solution analysis


The first picture shows the new McLaren from above. In the blue circle it is easy to see the exhaust ‘bulge’ and exit channel. The fact it protrudes from the sidepod is the first clue that McLaren is trying to do something clever with the exhaust flow.

There has been a lot of speculation about exactly how the device works but it is likely to exploit the Coanda effect to seal the diffuser.

The Coanda effect is when fluid is guided by a nearby curved surface to modify its direction. As the surface curves away from the flow it creates lower pressure close to the surface. This pulls the fluid towards the surface.



Interesting article via F1 Fanatic. Here is the Link

F1 Fanatic is not one of the best websites, i agree. I don't go on it at all.

Anyway, what are people expecting McLaren to come out with for the next test? Perhaps a refined exhaust layout?

The pre-season rumors were that they had a "revolutionary rear wing" that would be introduced at the final test or first race.

[SiLo]

Revolutionary? There isn't too much they can do with rear wings, unless they have a very strange chord shape and flap arrangement. Can't wait to see if this rumour is true though.

That was my thought too, we'll see soon I guess

[Shrieker]

Could you place the DRS flap under the main plane, or am I spouting utter rubbish yet again

I don't think there would be much point to that as it is effectively an extension of the main plane. As another non expert the way I see it is that when it flips up it becomes aero neutral and at the same time reduces the chord of the main plane and therefore the drag.
