    I really just want to stress that the graph lines from 4:20 to 5:40 are just really rough shapes off what I would guess on the fly by eye from 3D extruded wings from these airfoils, depending on the specifics the blue foil may have a higher peak downforce than the purple one, it massively depends on the geometry of everything. The point of that video section was just to get you thinking on the fact that the downforce curves can have different shapes and peak magnitudes.
    Hope everyone enjoys the video!

      Hi Kyle, I want to tell you that I like your videos so much and also I want to ask if you have a video explaining the aerodynamics of the "bridge wing" of the 2008 regulations and why FIA introduced a mandatory section later on.
      I really don't remember who made that cool video, I watched a couple of months ago but I haven't found it again, don't know if you made it and then delete it. I don't even remember if it was in Spanish. Cool you explained porposing thank you so much

      Not to be critical (I hope you find it useful actually as a reminder) ... but pronouns (when we can't see what you're referencing - as I'm thinking you might ... have noticed during editing?) really should _never be used in your demonstrations._
      Granted, sometimes the point is so obvious that you can use pronouns. but in that case, the sentence wasn't even necessary I think. Unlinked pronouns can only undermine an explanation's efficacy.
      I have a friend with _intermittent [eye cue] aptitude_ who'll say insightful things like, "I'm here" ... as if that's informative or as if I know where "here" is (which he didn't understand). I then asked, "when would ... or even _could it_ be false for you to say _I'm here_ ..?"
      I tried explaining that "here" is always the pronoun of where you define yourself to be. I think his Theory of Mind is the issue ... and, we don't choose our brains. We're just lucky or unlucky ... and if I understand something, it's not always because I deserve to, so I try to be patient ... and explain as best I can. But people who like racing (I'd assume) aren't people _known for their patience._ :-)

    I haven't finished watching this yet, but thank you for making this video. It's driving me nuts how many "arm-chair engineers" think they understand porposing "how hard can it be, the car just sucks down too much" and leave all these smug comments about how silly it is that they have this issue still because they solved it in X. Yet they have no idea whatsoever how complicated it is and why a "solution" from 30+ years ago won't work today.
    It seems to me that older F1 fans in particular (people like Peter Windsor) seem to have this gate keeping mentality about how engineering was "better" back in the day and how current F1 engineer's arrogance is one of the root causes of this issue . As someone that did FSAE and knows current engineers in F1, it just drives me up a wall as that thought process is absolute bullshit. I don't blame the F1 tech explanations F1 does as properly explaining it in 3 mins is impossible, but at the same time I wish they would emphasize more how much more complicated it is than the high level explanation they give.

      I've been patiently waiting and hoping for Kyle to drop this video cause I knew he would go into more depth.

      "the car just sucks down too much" Yes, the car is going wrong by doing what it's designed to do... Yeesh, I hadn't heard that one yet around my parts, the worst I'd heard was that the teams suffering the most from porpoising were trying too hard to optimize for absolute peak power near the ground (as opposed to not aiming as hard for peak and designing for a more stable "great" range).

    Carroll Smith talked about proposing in his books. Back then it was generally the download reducing ground clearance at the front wing to the point where it would choke off the lower surface and, effectively, stall the wing …. Reducing the download and causing the car to pop up. As I recall there was some natural frequencies within the car would amplify the situation.

    You can recreate porpoising in your own home. Get two spoons, face the two spoons away from each other pointing downwards whilst keeping them close to each other (almost touching but not quite). Then run them under a tap, and they'll be pulled together until they touch, then disconnect repetitively.

  • @david1rosenthal
    @david1rosenthal 2 ปีที่แล้ว +1

    The hysteresis explanation is the one that makes the most sense to me. The suspension dampers will be working pretty hard to dissipate energy from porpoising so something has to be pumping a decent amount of energy into the system to keep the oscillation going. The shape of the downforce vs. ride height curve might be wacky (and might even admit multiple "stable" ride heights at a given speed!) but I think it's a red herring as it doesn't answer the question as to what is putting energy into the system (if downforce was purely a function of ride height then going up and down any such curve would be energy neutral.)

  • @thethirdman225
    @thethirdman225 2 ปีที่แล้ว +1

    Great explanation Kyle. I’ve been looking forward to this for months. I was one who -probably- got it wrong because I saw it as a pitch problem that simply (nothing simple about it) meant less downforce as the rear springs compressed, due to a less optimum AOA. I definitely get the hysteresis component and that explains the cyclical nature of it perfectly.
    Thanks so much for putting this together. It’s so much better and more complete than anything else out there.

    If the wing touches the ground the stagnation region grows like crazy, I paid attention when you were talking about adverse pressure gradients. More stagnation leads to more APG, more APG means more turbulence and recirculation ie lots of drag and losses. Turbulent airflow is on average about 1/3rd as efficient as laminar flow depending on surface roughness.

    The 3rd example is closer to the 1981-82 "fixed" skirt f1 cars, the modern cars have a variety of tunnel shapes. If you look at the pictures of the Mercedes floor from the first few races you see that their tunnel shape dipped very close to the bottom of the lowest parts of the rest of the car, That effectively not only created massive potential downforce, but also made it easier the flow to be choked off as the car lowered at higher speeds.

    Brilliant video Kyle. I'm glad someone is using proper engineering tools to understand engineering problems. And even though you don't have the actual data about the dimensions and operating condition for these cars, an educated estimated still works in explaining the problem.
    My only feedback will be to show the legends and magnitudes for all the plots because otherwise we are just looking at colors and distribution patterns. If I want to conclude that the static pressure advantage of the low-ride configuration outweighs the energy losses, I would like to see the magnitudes of the static, dynamic and total pressures. Also maybe improve the comparison by showing the two test cases side by side instead of flipping through them in the video :) In any case, this is a fantastic video. Waiting for more content!

    With the bit @22:08 I'm guessing this is why we saw the various stays being used on the floors.
    Guessing Mercedes designed for maximum downforce with what they thought would be an acceptable level of porpoising. However they weren't able to forsee it hitting a natural frequency in the chassis.
    Wonder if Ferraris front wing design was done so it would give clean flow to the floor and reduce the size of the vortex heading into the underside.
    Interesting video as always 👍

  • @stevenanthony578
    @stevenanthony578 2 ปีที่แล้ว

    FWIW... you showed how the RB floor generates lots of different vortices with various elements--some smaller than others. I wonder if the range in sizes act to kind of take over for another when it breaks down. So, as the the primary vortex starts to fail as the floor lowers, a smaller ones fill in the gap--and as the floor lowers more, causing that vortex to fail, a still smaller one seals off the floor. So you get a constant seal effect over a greater change in floor height, and thus, less oscillation. On the reverse direction (the RB does oscillate a bit), the floor recovers sooner as one of the smaller vortices comes back. The net effect would be it takes longer for the RB to stall out completely, and it recovers sooner.

      The problem of porpoising is somewhat inherent when the emphasis on underbody aero is really high, but I think the really bad 70s and 80s problems were still to a large extent caused by it being a very new thing, that was quickly copied by others without necessarily too much understanding of the whole subject.
      People tend to forget that after the "ground effect ban" of F1 (a term that I hate because they never stopped using ground effect, they just banned specific types of structures that exploit it very efficiently) other car classes like Group C and IMSA's GTP made immense use of underbody Venturis to gain huge levels of downforce for a decade or more, and they weren't constantly complaining about porpoising.
      Which isn't to say that it's a simple thing to fix it, by no means. It's definitely a complex subject, but the people working on these cars are clever, and they'll figure it out after a while. I'd be highly surprised if cars next year and the year after that haven't been able to make a lot of progress based on what they learn this year.

    Little is said about the ratio between tyre wall height and (centrifugal force from) wheel weight on contact surface.
    Where is the sweetspot that no longer the tyres can absorp the increases in downforce from accelerating.
    Distance means leverage effect, so a slight change of distances between sources of airflow rearrangements, can mean a world of difference.

    The porpoising is caused by the flloor area near the rear wheels for 2022. In 2020, the floor went all the way out to the rear wheels. In 2021, the FIA cut the floor slightly near the rear wheels. Yes, the rear diffuser is also different from 2020 to 2022.

    Hi Kyle, very interesting and instructive video. Could you maybe do an analysis about the Porsche 919 Hybrid Evo? Even though it is already three years old, that car is, in my opinion, astonishing fast, as it broke the record on the Nuerburgring Nordschleife by far and even was faster than a F1 car in Spa. And because of the sideskirts, I think they are also using the ground effect, but why isn't porpoising a problem there? Would be very nice to see the details of this car explained.

    Hey Kyle. Question. Regarding the red bull. If I am understanding this well, could this be why Newey chose the current RB floor design? It looks like he is using the fairly large front floor area to energize the diffusor kick and potentially illuminate most of the issues causing porpoising?
    Thanks again for another amazing video!!

  • @charlietaylor3600
    @charlietaylor3600 2 ปีที่แล้ว +1

    Super vid, from what you've said though, doesn't seem like the 'no side pod' aspect of the Merc should cause porpoising so how come there's chatter about running the barca test spec?

    • @benfulford3943
      @benfulford3943 2 ปีที่แล้ว +2

      From my understanding the reason they are suggesting this is because they aren't able to hide extra supporting structures for the floor in the side pods. This means their floor is bending more at the edge of it causing the porpoising to occur more quickly. I believe the new floor they have for this weekend has an ice skate along the edge in front of the rear wheels that potentially might help with the issue. I guess we'll find out tomorrow

    Can you share a pressure color scale for reference?
    Also why vortex becomes an issue at some parts of the car but then purposely generated at some other sections?

    Can you review Ken Block's new Hoonipegasus-thing? Its a hill climb car scratch build based on the 911 on looks I guess. There are some interesting-looking aero bits, with similar details found on F1 front wings from yesteryears. I'm curious if they look like they actually work from the eyes from a former aero engineer...

      That car panders toward a particular niche market. If it aint broke, don't fix it.!
