McLaren MP4-27 Mercedes (pre-launch speculation)

[allstaruk08]

csponton your source is your own blog? in that case the mclaren will be blowing the diffuer, they will have a front wing F-duct actually doesnt blow the front wing it blows the beam wing my source is my facebook page (im being sarcastic incase someone doesn't pick up on that)

Leave him be. He was spamming here last year even more as far as I remember...

I ve heard somewhere that Ferrari and Red Bull will have the max bulkhead height (inmyho 625mm), while McLaren's front will be lowest.

Return of the ant eater???

I wonder if you could build a passive system under the engine cover similar to f-duct, that stalls the rear wing above a certain speed ? McLaren probably has the biggest experience when it comes to stalling the rear wing. I would expect it from them.

Guys what is actuall stall of wing?? Could send on PM

I think McLaren's car already had one of the lower bulkheads/front ends on the grid was it was. I know this because I joked that Hamilton would crash less as he would have a better view in 2012 but someone came in and said, well he had a good view in 2011 too. Ha.

An aerodynamic stall is when air travels faster on the wrong side of the wing. It causes the wing to generate lift in the wrong direction (on a plane, it generates downforce, on a car, it generates lift), and it can also cause a significant reduction in drag.

I would rather describe it like this;

Stall is when the side where air travels faster(and has lower pressure) detaches from it's surface, suddenly reducing lift from the surface and often is coupled with a big addition of drag.

A crude explaination since it goes much deeper as there are different types of stalls, based on location where it detaches(for example at the leading edge or further down) as well as other things.

Stall causes a big addition of drag?? I think not.
Basically the flow structure over/around the wing is altered as to reduce lift and drag. It does this by detaching the streamlines (air flow) from the wing removing the shear forces acting on the wing (which is how lift is created, not by a speed difference across each side)

Hope that helps

No it does not. In controlled environments like the F-Duct of the mclaren for example it indeed does reduce drag. However uncontrolled stall, by pushing the wing surface to far it will cause drag.

aleksandergreat I suggest you read these:

Yes a wing will stall and induce drag at a high angle of attack, but teams blow the wing normally (i.e not tangential) so it stalls to reduce drag, is the key thing to know especially bearing in mind we can't even decide exactly how a wing generates lift!!

Just to clarify, lift induced drag decreases, but drag due to turbulence behind the wing increases, but CFD and wind tunnels make it very easy to remove this.

Stall is when your machine has a drastic loss in performance. It can no longer works to provide the primary motion. It stalls.

Engines can stall too... piston engine.. the gas turbine engine (compressor stalling).. You can stall your bycicle.. You can stall while running lol.. And aerofoils can stall..

The aerodynamic stall for the rear wing is when the wing has a drastic drop in down-force. Usually caused by detachment of the airflow under the wing.

Thx guys now i exactly now what is stall of wing. Actualy i dont understanded what this a word stall means! Thx for all obligations!

So i will make summary: Stall of the wing reduces drag penalties under the wing... Basicaly make same task like cascade wings... thx

Wandered past a beautiful MP4-27 tub in MTC today. Already looking smart - can't wait to see it completed on Feb 1!! #believeinmclaren
