McLaren MCL36

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

1 - The diffusers don't flare out laterally any more.
2 - The duct is extended downwards, not rearwards.

They don't flare out as much as they used to, and what is happening to the air between the wheel winglet and the wall of the diffuser, does it not exist? You completely dodged the question.

What do you think is happening to the air that's passing by that yellow line?

No, they just don't flare out. It was prohibited in the rules.

That's going upwards, not outwards. Check the straight metal plate at the bottom. Or absolutely any photo from directly behind the car. There's a thread here with dozens of them.

Indeed. And I notice that some teams have an inward deflection of the diffuser upper corner just before the rear edge - it's visible on the McLaren image. This presumably allows them to form a bit of lateral outwash in the top corner of the diffuser.

Don't believe your lying eyes :lol: 3 cars 3 different attempts to create outwash with the diffuser within the regulations with flowvis to boot, but yeah. Fake internet points = correct around here I guess.

You are seeing what you want to see, not what is actually there.
The impossible often has a kind of integrity which the merely improbable lacks.

I think you were saying the diffusers kicked out where the brake duct wing is, but this is not evident in the photos you posted. I see a straight wall on the side, and the only sharp bend is vertically along the topside edge. There's something in the regs forcing this, otherwise we see other types of shapes amongst the teams. Remember previous seasons, where the diffuser side was as curved as the diffuser ceiling? Triple gurney flaps on the vertical edges. That's not present in these photos. Compare to the RB18, it's basically straight sided all the way to the end. If anything it gradually tapers in toward the end, away from the brake ducts.

It's very easy, if the effect was as powerful as you think it is (apparently based on your setup in a computer game, that doesn't model airflow at all and doesn't even model tyres correctly) - every car on the grid would taper the rear brake ducts from very narrow at the front to wide at the back to accelerate the airflow between the side plate and the diffuser.

Not a single one does.

What you are seeing is the radiused corners at the top of the diffuser, but the vertical walls are not flared.

This is a Red Bull but you can imagine the same for Macca.

Any guesses how much that weighs? Two guys, barely straining, holding it by its thin fins. 15 kilos?
