    Simply put: channel the air around your car. Redbull does that by disturbing the airflow and channeling the disturbed air around their car by their bodywork. They use high pressure creators (undercut sidepod) to make the air particles want to escape and also channel a way for the air particles (along the sidepod and to the diffuser) to facilitate the escape. And I would love to explain how they actually do that, but you've done that already dude. Great video👍

    People should be kind since you are trying to help novices such as myself as well has build the engineering community. I have no experience with Aero, so any bit you explain helps me. I guess by big question that I keep coming back to is why th W13 was hailed as having so much DF at the end of the season last year and seemingly lost it over the winter. I realize the W13 success at the end of the year could be attributed to track specificity but it still perplexes me. Can you/have you done any comparisons between the 2 cars? Thank you.

      Because Mercedes pushed to have the floor edge and diffuser throat raised. Ironic, that Mercedes basically neutered their own car with the regulations they pushed for. This isn't new, they did the same thing in 2021.

    Thanks for you in-depth explanations. This helps us to gain a greater understanding of how each team creates its down force

  • @rolandotillit2867
    @rolandotillit2867 Год назад +6

    I have a few theories. A big one I can tell you right now is that their diffuser is much more carefully sculpted. Every other team just tries to maximize the volume of the diffuser, Red Bull sacrifices some volume in order to keep the expansion nice and smooth all the way to the beam wing. If you look at the telemetry you can see that there are cars that have more downforce than the RB19, they can accelerate harder out of mid and slow speed corners. Next because the volume is smaller, the peak downforce is less, and you can see this in their top speed. Can't have downforce without drag.
    Of course this is hugely simplified so I can fit it in a few sentences, and there's much more involved.
    The floor fences are also a huge part of the car's performance. The underbody vortices restrict airflow along the tunnels, and keep the flow attached very nicely.
    It's like putting your thumb on a garden hose, without your thumb over it, water flows out at a velocity dictated by the pressure gradient. If you place your thumb over the hose at just the right amount, the water flows out faster. Either side of that sweet spot, the water fails to flow as fast, or at a lower rate. The vortex generated by the floor fences is like your thumb in the garden hose analogy. It has to allow enough air in, and restrict it just enough to accelerate it.
    If you look at a centerline pressure plot of these cars like Nelson Phillips does here ruclips.net/video/PEVaBx_UOko/видео.html&si=EnSIkaIECMiOmarE&t=382, you see the pressure spikes at the fences, then drops off sharply.

I'm asking regarding vectors of forces generated, because it is not obvious from these comparison, that despite the air controlling differences how the cars should behave differently.

    The Mercedes sidepods seems to make the air turn too sharply near the edge wing. Air doesn't like to turn more than 15 degrees, not in engine intakes, and not in planes or cars. That's why your typical 3 angle valve job on a cylinder head is spaced out in 15 degree steps(30/45/60). And the more angle steps and the shallower the angle for each step, the better it is for airflow.
    The Spec 1 AMR 22 had HORRENDOUS separation at the trailing edge of the side pod precisely because the angle change was like 60 degrees with one continuous radius. I mentioned it in the car thread on F1 technical, something to the effect of "how much separation does that make?". Yes I am public enemy #1 on that forum aka godlameroso. Now serving my second 6 month ban.

    What if Red Bull has very stiff high speed rebound damping. When you have a strong rebound damping force, hysteresis can cause the car to jack down. Perhaps at a certain speed, the porpoising frequency is absorbed by the suspension, and the rebound damping jacks the car down onto the bump rubber. The natural damping from the bump rubber becomes the defacto suspension at a certain speed as the normal suspension collapses in response to porpoising.
    It was easier to do this last year, because you could run the car lower, even the technical directive mid season have no real effect because riding on the bump rubbers limits how low the chassis can go better than the suspension can. Only problem is, the new suspension ride heights, now they're affecting the driveshaft angle, and it's causing issues with driveshafts, and wheel bearings.
    The original Mini Cooper had rubber suspension, it was a light car, but meant to have big occupancy. If you increased the mass of such a car by 200kg worth of occupants, and luggage the suspension would not cope with that, so the Mini instead was made with rubber suspension in place of springs. Could something like this be at play in the Red Bull?

      This is what I think is happening with the floor. The innermost floor fence and the body of the car create the first throat, and the throat of the diffuser is the second throat, and the diffuser is the subsonic diffuser. This only happens at high speeds, but I believe RB's floor is designed with this in mind, attempting to achieve a "started" channel. This reduces drag, while maintaining downforce.

    @TheNamesBettyNyahhh Год назад +1

    I've read that RB (and possibly AM) have found a loophole in the regs enabling them to create a pretty special 'trick' where their single-pillar rear wing also connects to part of the rear suspension. At speed the pillar flexes slightly and, combined with clever under-floor architecture, effectively simulates active suspension. Perhaps that's why Ferrari have also been trying to persist with a single rear wing mount. What do you think about that?

    THANK YOU so much for another aerodynamics view point ! The AMR23 & W14 comparison videos help explain so much and really solidified my thoughts of just what is going on with Merc's issues ! I'm a RedBull and 100% a MAXattack fan from day one of him coming into F1. His approach was a much needed asset to the stale driving and passing F1had become. YES he made mistakes on his way to the front. Sure he was aggressive, and probably pushed the boundaries of it to the limit of what the older drivers thought it safely allowed. But as F1 grew safer its drivers grew to safe in their approach. Maybe being limited by the governing body too much as well ? But as always in F1 you need the WHOLE PACKAGE as a TEAM ,not just the driver ! Going back starting right now with it's RedBull that has managed to put it all together once again as a entire team package. Merc killed it at the start of the hybrid era. RB had it their 1st run of 4 with Vettle driving. The one off year of double defusers with Brawn. A couple runs of doubles with Ferrari and Renault (with Alonso's back2back🏆) Ferrari's big run with Schummy. Then Mclaren ,and Williams had their big runs of 🏆titles as well.
    The point being, the teams that get it all right and have the best driver's also, usually have a pretty good run of dominance for a period of time. As long as the regulations stay relatively stable that is. It will be intresting to see if the FIA steps in AGAIN in attempt to knock RedBull down to even things out. They screwed but also helped Merc during their run. It all depends on how much the other teams use their political power. And if viewership drops off cause all the Drive to Survive and Merc fans loose intrest and tune out. Cause they all seem to hate MAXattack & Redbull . But most of all anyone other than Lewis and Mercedes winning !!

    Shub, my question is a bit more general. You go into some great analysis on the cars. But when a team comes up with a new design, ie how they decide on what the car will be like for the coming season, how do they decide? Do they go through an analysis of the competitors from the previous season, try to understand what the comp is doing and then come out with a best guess for the new year?

    Unfortunately, I can watch the video only tomorrow, because I'm very busy today, but what surprises me very much is the much lower pressure build up on the rear tire of the Mercedes. The W14 should therefore have less drag. Likewise, the rear wing of the Mercedes seems to work better, as there is a higher pressure on the top than on the AM, while the airflow over the sidepods look much more controlled and smooth on the AM and not really controlled on the Mercedes without any real direction and goal.

    Thank you for another great video!! Question. Am I right in saying (in extremely simplified terms) that Merc is essentially attempting to power up the diffusor by feeding as much air as possible to the beam wings (which would explain why their flow pattern in the rear looked so..."efficient" and clean to my eyes when riding through wet patches during the shakedown) but Red Bull and Aston are focusing on maximizing the mouse and flow structure in that region instead? And that method is simply the more effective way to go?
