How do the Mercedes Sidepods Work? - Aerodynamic Analysis
Автокөліктер мен көлік құралдары
In quite a visually apparent update to the car, Mercedes has brought quite a radical change in sidepod concept to the W13. They have essentially created a large downwashing wing with a shroud around the side impact structure, and then have inverted the sidepod inlet and put it towards the floor. This seems to be in an attempt to get more downwash and stronger vortices from the top of the sidepod, but the legalities are certainly interesting!

When working with Mercedes, if another team were to unveil such a different concept would a deep analysis go into working out the benefits and or if it’s possible to go on?

Can you talk about porpoising in depth some time? I understand the basics of the floor air flow getting choked but I'd like to know more about what can be done aerodynamically instead of just stiffening suspension. Do you think there's an underlying reason we've still seen teams still struggle with it in Bahrain? Nice work as always!

Floor flex. Teams weren't quute prepared for how powerful the floor would be so the ends are flexing at high speed and causing the choke. If you look at the Mercedes you can see the stats they've added to help although at the ground clearances and speeds even that isn't quite enough

@@RCmaniac667 there are a lot of things. First the front produced way more downforce. That is easier to balance. They also did gain a lot of downforce with the floor but the percentage is a lot higher now. Most part of the rear downforce was done by the diffuser and the rear wing which are not influenced by the car in the same aspect. You also didn’t habe the tunnels. The floor was quite flat from the beginning now you are allowed to get more air under the floor because thats what ground effect is for
@AdrianTuhut

Nope, it's not floor flex. Imagine this: the car is drawn towards the ground so much that the air that is directed beneath the floor has no where to go so it takes other routes. In this way no more air is flowing under the floor, so the car 'stalls' and there is no more ground effect and it goes up. The air now can flow under the floor and so on and so forth

Less than 2 minutes in, and you already spoke more sense than most media outlets. Why are so many people calling this a "no sidepod design"?! As you correctly mentioned, the volume is there. It has to be there! The rads have to be somewhere... CE hardware has to be somewhere... the fuel cell has to be there somewhere. The team pulled off an absolutely spectacular sidepod design concept... but the sidepods are there! :)

Hi Kyle - I enjoy your channel very much, and your style of explaining complex concepts very clearly. A request - would you consider putting together a video that explains the processes the Teams go through to take the rules, break them down to develop a concept that they think will be the best performing within those rules, and then develop all of the features and intricate details that turn that concept into the car that hits the track. It must be an incredible challenge, when the time and budgets are constrained there is so much at stake.
Literally checked your channel 4 or 5 times over the last 24hrs waiting for this 🤣
Great video and content! I have a question though: if I remember correctly, in some other analysis videos you mentioned how the shape of more conventional side pods would create an outwash that pushes the flows away from the rear tires. In this new design it looks like this is not possible given the narrow section of the car body: isn't this a drawback of this interpretation? Or rather, the vortices spun by the winglet they introduced in place of the pod are sufficient to limit this adverse side-effect? Thanks again for sharing your expertise, your channel is amazing!
This is exactly the video I wanted to see. A clear explanation of what the rules are and how this design meets them. Excellent work

Great explanation. Especially the 3D model section. All the other reporting focused so much on just how slim the sidepods/inlets were but I haven’t seen anyone else mention anything about the “wing” under the mirror and how Merc is justifying it as part of the sidepod.
That is probably the strongest mirror stay in F1 history… 😂… It is literally held up by the side crash structure.

Great video! Really great in-depth analysis and breakdown of the rules.
Aot of people still seem to be worried about porpoising. Yes the merc was bouncing a lot on the straights, but they had several runs where that wasnt the case. My guess is, that they are trying to find the sweet spot, where they have a lot of downforce without porpoising. This is still testing after all.

Great detailed explanation - I’ve learnt so much of what I didn’t fully understand of my favourite sport in the last three weeks from you - so thanks 👍🏼🤝. Just have to say that my biggest surprise from the Mercedes’ new side pod design is the side crash structure. I had always assumed that it also compromised an upright section to form an upturned L shape. Thus I didn’t realise just how vulnerable the drivers actually are on either side and amazed that there hasn’t been a serious injury from something piercing the side of the chassis underneath the side crash structure. It’s also a testament to how strong they are when thinking about all the accidents similar to Verstappen’s 2021 Silverstone one; the forces at work and it withstanding them is quite something. 🤯🤯

Very interesting video and awesome way to explain the content! I loved it! I have a question, according to your explanation, these new sidepods with this "vertivally stretched section" require clean flow to guarantee a good air flow for cooling. Do you believe it is already possible to guess what would be the effect of following another car on the "cleanness" of the airflow towards the sidepods?
best explanation of the shape of that sidepod and the mirror holder/crush structure. It looks like Merc had to compromise a lot with the shapes but they really wanted that vertical small inlets and came up with a smart design, satisfying the rules. Which means it is probably worth doing it. Far much smarter than I assumed tbh.
Id be so happy to a video of you designing aero for f1 with no rules. Just pure performance.
Can you do a video explaining how the flow vis paint works. Or really, what information the teams get from using it. Perhaps you can bring up pictures of different cars that are using it, and tell us what info you’d derive from it.

Been eagerly awaiting this video! Probably better than any breakdowns done by other channels. Didn't even miss F1's Tech Talk during all this time since this more than filled that gap. Thanks for explaining how the new Merc design is rather questionable in legality, I don't think anyone's really clarified that yet to the rest of us. It's really innovative stuff, now to see if they'll tighten up the rules around it in the future, or if it's even worth it to begin with.
Amazing video. Thanks for the great explanation.
That was very much appreciated, especially in light of that the F1 channel puts up dunderheads on "tech" presentations who think pointing out trivial differences in looks is technical description. One of them recently remarked on the Merc, presuming the inlet is smaller, "I don't know how they are going to get sufficient air into the engine." That's not all they don't know. They ought to have you on, but I'm subscribing here today.

This was great. Everything I'd assumed (and heard) about the sidepods seemed to have been wrong. It makes a ton of sense now, as well as why other Merc engined teams might not be running more unusual cooling setups. Ie its not the cooling or sidepods at all, its the down washing winglet.

Wont this slot make the structure weak or Merc would have to reinforce this piece to bring in Stiffness. right ? 2) how does a this stand alone Winglet structure with large overhang from body help to protect driver in case of side impact ; section height is too small & coupled with the under-side slot for regulation this makes it weak. Please comment your inferences. Thank you

The winglet itself IS NOT the side impact structure! The side impact structure is a standardised part that's the same on all of the cars. On the Merc - instead of being shrouded by the sidepod - it sits inside of that winglet. The winglet itself is just bodywork, and has nothing to do with the actual impact structure, therefore you can easily have a slot there without having to worry about crash safety.
