Was looking at the F1 cars for this season when i noticed that the Mclaren MP4/25 had its engine air intake shaped like a wing.

At least it looks like the principle is there.


How do i scale down pixs?

its humongous!

The only car in the grid with that fatty bulp on top. I think that bulp is gone by the end of the season.



Ferrari also got a shorter wheelbase and a minimalistic design.

It might look like a wing profile but that cannot be the 'principle' because that shape is used to generate lift. More to do with drag and making the rear wing more effectively, I'd say.

PS: You should of (yes, of) used a thumbnail.

thumbnail is found were?


the profile in my eyes is upside down so it would generate lift downwards if i must say it difficult, and yes i must. :P


If questions is a necessity it would be more like; what gains is it on a short wheelbase car vs a long one?

or couldn't the bulp disturb the airflow in the middle?

the air between body work and top.

i think it will.

The real answer we will have at the end of the season.

At least one of the cars looks different! Halleluja! Or whatever...

Yes, essentially.

If you are going to be wrong at least be proudly unrepentent

Or even 'have' used...

Perhaps the bulp works like a wing but with a different goal. lets say the bulp is sucking air up right before the rear upper wing profile. sort of filling it up.

[zac510]

The thing about this bulb is that people are thinking that the fin is possibly hollow and feeding the inside of the rear wing with air which is injected into the low pressure/trailing edge airflow:

But any 'sucking' at the top means lift (Bernoulli's Principle), no way around it. For all we know there might be a certain amount of lift being generated there, but it may yet be the preferable shape when you consider the car as a whole. Also, bulp? If we see it from overhead it would have a rather coke bottle shape, wide at radiator inlets but compressing as it comes close to rear wheels, yes.

A GIS for wing profile should clear any doubt about wings.

Like a aid to get the air on the "downside/backside" to follow a steeper angle before slipping and creating a stall?

It can still have multiple purposes.

i clearly see a upside down wing profile in that bulp.

i meant sucking air on the sides/downside not on the top.

air got momentum too and it is compressible.

Do it right you should be able to tweak some more air on to the top of the wing.

Upload it here first, then resize. Post the link from there. The resize option is available if you tick on the edit box before clicking "Continue"...

The benefit of such a design would be reduced drag. Like those afterbody mods for trailers which try to reduce drag by allowing some air to fill in the low pressure region behind the trailer. Of course, since this is F1 comparisions with base bleed artillery shells would be more appropriate.

You'll have to draw some arrows and tell me where air is coming from and where it is going, since we seem to be talking past each other.

Here is your drawing.

I really like the cars now.

better than when they had devil horns on the nose and vorts on the side pods.

yes the front wing could have been smaller but all in all they are god looking with their slick tires and smooth bodies.

[Powersteer]

About time, I've drawn an intake inlet that way ages ago I'll scan some and post it....maybe not.

This week's Autosprint states that the driver can fine tune airflow to the wing by moving head.
They say the trick is accomplished by the driver reclining his head on straights; this would change airflowto the intake of the hollow dorsal fin and the result would be a downforce-drag reducing rear wing stall.
I guess the drag reduction would come from an induced drag reduction compensating for a profile drag increase coming from the stall.
If it is true it is astonishingly clever and legal.

Soon we will see aero trickery on top of the helmet.

I always argued that driver's heads were moveable aerodynamic devices and should be banned (since they're already binned).
