Well Hello Blue Sky! I've created an account here to hopefully from some cool Motorsport Tech content over to this world. Hopefully it doesn't erode like my Threads experience did. Let's all just be happy nerdy Motorsport tech stans together! Harmony! Peace and love friends!
In my analysis of the McLaren MCL39 FSUS junction update, I had questioned if the new aggressive upwashing junctions might shed a small vortex that could re-energize the slow moving boundary layer along the nose.

McLaren introduced a new front wing with some interesting little end element winglets. IMO, these aren’t really wings generating much load. They are more vortex generators shedding counter-clockwise small vortices that all co-rotate and merge downstream…cont

Heck of a glow up for McLaren from 2022 to present on the front brakes. From a liability to an advantage. That’s just great engineering folks!

Been thinking about this new Sauber Side Pod intake since I first saw it. Pretty cool little design. Here is what I THINK is happening. 🧵

Some are calling the new Mercedes W16 side pod the “tadpod” as it looks like the shape of a tadpole. Pitlane shots from Albert Park now shows how Mercedes did this. You can see the “belly” of the tadpole shape where the rads are located and stacked.

LOVE FLOW VIS!! RB21 here...
Red arrow shows that the aero neutral suspension arms aren't as down washing as some might expect. This shows an upwards trajectory after the rear leg from the flow coming off the front wing. We do see some downward deflection from the flow UNDER the trailing arm.

When I first saw the flow vis posted by @xaviimages I knew something was a bit off. It’s not typical that you see these types of patterns. Even with the new cut end wings (see MCL from 2023) the junction from where the DRS and end piece meet is usually uniform and neat…

A good look at how the Mercedes W16 forward floor is working. Pretty standard solutions today using a small forward edge gurney, and integrated curl with VG's on the edge wing. Always a good thing to explain for some that may not have seen this before.

Really interesting look here at the RB21 G-Line. There seems to be a slight bulge maybe in the floor (Blue) which funnels the floor edge wing inflow into a particular position. Possibly some influence from the forward curl? The mechanics here are fascinating.

A good photo from Mateusz M on X where we can draw a few observations from this. Firstly, we can see the influence of the floor leading edge in helping to upwash some of the inboard air from the nose and FW,

Nice graphic showing the types of vortices that can be formed at the junction of two surfaces. Easy to see this as an example of the a-arm fairing junction with the monocoque. Without junction fairings (gaiters or flexis) the losses could be disruptive to distress aero elements

I love how this image shows the natural relationship and intent of aero features to serve a purpose. The alignment of the leading edge of the shark bite with the upwashing flow from the front wing, the outboard sidepod shape to build static pressure to hold the upper front tyre wake outboard…

Nice top shot of the FW47 showing the minimal engine cover gulleys. You can see how they work to hold the cockpit losses high and keep it contained. This keeps the losses from migrating down the engine cover and into the water slide on the sidepod feeding much needed energy to the rear of the car.

Cheeky little tech feature on the MCL39. It's a split strake with a single slot bypass on the lower half. Like a multi-element wing, this slot gap helps to energize this lower half where junction losses at the intersecting point with the body would be present. This slot bypass..

MotoGP aero is getting really fun to watch. Stacked wings, cascading winglets. Lots of fun stuff to see here. All in the name of bringing some rear load, and slimming wakes from bluff structures. 😍😍

The 2025 cars will soon be here, and one specific area I will be paying careful attention to is the forward floor, and edge wing designs. In Adrian Newey’s latest interview with AMuS, he mentions the importance of finding solutions for Venturi ground effect floors....

I’ve been a bit quiet around here because our 4th child was born a few days before Christmas and life has been a bit chaotic 😁. The family is doing amazing, and our little dude is healthy. Also, my wife finally talked me into doing one of those newborn photo sessions.. 😂😂. So enjoy. 😉

I've posted on this point a few times now, but it's worth a reminder.
There will ALWAYS be differences in thought and development philosophy in teams. RBR is not the only one to have suffered from this. Just look at the tragic story of the W13 and W14 for instance…

Why does the front wing matter so much? And how does front wing element flexibility make a difference to the balance of the car?
Well the simple answer is… it’s not that simple of an answer. 😂
