Red Bull RB19 - Aerodynamics Analysis and Initial Thoughts

[@KYLEENGINEERS]

In the interests of keeping this video professional and on topic I cut a 5 minute exposition on flow vis analysis at the end. The TLDR of it is be careful of reading flow vis pics as it may not be dried in track conditions yet, and *definitely don't try to analyse flow vis on a car that hasn't even left the pit lane!* Hope everyone enjoys the video and feel free to drop your speculation about any upcoming Red Bull Aero Updates below!

[@MV-vv7sg]

Hmmm. Are you being oddly specific about analysing flow viz in a pit lane photo for a reason…? Merc vs Pink Mercedes again… former engineer edition…

[@TassieLorenzo]

I wonder why Red Bull used such a bright colour that everyone else could see instead of using UV paint or something? 🙂

[@CosmicSeeker69]

​@@TassieLorenzo I don't think that it matters. The results will be team specific - given the multiple elements that combine in a full aero package. Could be wrong but....

[@rfour.]

Would be really interesting to see a video specifically on flow-vis analysis and how it works, what to look for.

[@giovannig4369]

Little dig there at the other aero f1 channel. Totally with you Kyle on this one though: I mean the car was truly still in the pits!

[@Cyyanss]

These videos have landed me in a cool opportunity. Know little about aerodynamics but was hanging out in a hanger while waiting to pick up a friend from a pilots license lesson and ended up in a conversation with one of the instructors. He went around the plane and asked for guesses about what features did and other stuff and the basic grasp I gained from these videos impressed him enough that the next lesson my friend takes the other instructor would give me a free flight to try it out. Love the videos and thank you for indirectly getting to fly a aircraft while broke in my 20s.

[@GreatistheWorld]

Brooooo congratulations CM that’s so cool

[@Cyyanss]

@@GreatistheWorld it was awesome, got to take off and learn all the checklists. Did some different maneuvers at 7500 feet.

[@IPL_VIC]

That’s awesome. I wish i could have an opportunity like that. My calc teaching told me i could be an engineer and I’ve f*cked it all up since 🤣 i need a second chance in life lol

[@Cyyanss]

@@IPL_VIC you got this man. I’ve screwed up every opportunity I’ve ever had until the last year or so. Keep grinding!

[@scottmcqueen3964]

Never clicked on a video so quickly

[@WeAreTheRace]

Loving your work! 🤝

[@zzzanimal1722]

i've never been so fascinated by something i understand so little of. just recently got into F1, but wanted to dive head first into the technical/science aspects of it more than anything. but boy it feels like i dived into the deep end lol. can't wait to keep learning and someday be able to watch one of these videos and understand most of it. you clearly do a great job with these and put in a lot of effort. thank you.

[@diamondfrost6937]

@KYLE.ENGINEERS Any chance of a video on the surprise reveal of Mercedes and RedBull floor at Monaco ?

[@TheDragonaf1]

ALL 3 FLOORS were shown in Monico this year (Merc, ferr, RB) will you be doing a video like last year comparing all 3??

[@armadillolover99]

Great stuff as always, Kyle. I’m curious though if there’s anything from the other teams that caught your eye on the first day (other than the whole Ferrari nose thing which I think we’ve all narrowed down to an unintentional weak point)?

[@ltitus8900]

Yo...best F1 season in a long time. Got Wolfpack performance providing a fire live stream, Kylee providing far better technical content than F1 themselves, F1 itself has FINALLY started and I got me a fresh coffee brew. Hell yeah.

[@JessSimpson1313]

Hey Kyle, awesome video as always! Now that we all got some really nice views of the underside of the floors in Monaco will you be doing any updates?

[@robertbaguma7540]

Waiting for the video for the floors as per Monaco 😂

[@michaeloxlong5697]

First for Eldrich horrors beyond comprehension. gimi.

[@Tekkas_GG]

Is it just me, or is RedBulls understanding of that floor more advanced than the other teams? It looks so complicated.

[@stevenst6337]

Newey specializes in ground effect aerodynamics, he wrote his thesis on ground effect in university which was like 40 years ago probably lol

[@davidaugustofc2574]

Also his thesis focuses especially on ground effect usage on sports/race cars. Newey was also one of the minds behind the change in F1 philosophy, the whole car works for the aerodynamic and not the aero for the car. His Leyton House also had a more efficient aero than the high nose Tyrrell, only having less downforce because the vortex sealed the Tyrrell undertray. But the high nose would become the standard anyway.

[@sampeter2714]

They bought the 2022 regulations so it would be a car Newey has experience on.

[@sampeter2714]

Ferrari has done under the table deals with FIA and engine regs. Redbull did the same with aero and floor. Obviously because they have Newey.

[@Tekkas_GG]

@@sampeter2714 what are you even trying to say here mate?

[@markwilson9509]

I wonder if the tighter and lower radius on the bottom of the side pod is a consequence of a slightly lower and straighter top to the side pod? Perhaps to retain internal volume / cross sectional area for cooling.

[@zandvoort8616]

The problem with F1 now is that it’s purely an Aero formula with no engine development allowed. That’s obviously going to play into Newey’s hands.

[@Zemmip]

I'd love to see a quick new vid discussing the version of the Mercedes that showed up to testing. Great stuff as always :)

[@liamcrofton1051]

Could you do a video on how to interpret flo vis, I think that would be super interesting

[@domserious7558]

Can you make some videos about the floors in Monaco?

[@baselanani2316]

Kyyyyyllleeee can you do a RB floor video from Monaco????

[@LukemanHakim]

RB19 look runs lower than rb18 from the sidepod comparison.

[@Pandamasque]

Everyone's hyping the "aggressive undercut" but to me the biggest change in the sidepods is that their previously curved side face (where Oracle and Siemens logos are) has been flattened so much that it seems concave from certain angles! I assume this is to keep the front wheel wake out for longer, which is a leaf from the 2022 Ferrari playbook. Curiously, in 2023 Maranello took a step in the opposite direction here.

[@singular9]

Are you going to go over the new revised mercedes design?

[@fillman86]

can you look more at Le Mans cars like lmh, lmdh and lmp2? I'd like a talk about the evolution from flat sides of the cars, to having side pods that look like f1 cars

[@kevinstoneman2386]

It looks like they aren't running any rake this year and in some photos it looks as if they might be running a lower ride height as well.

[@cliotrophy230]

Kyle, could you analyse the aero on the mcmurtry spéirling. 2000kg downforce even when stationary....using two fans!

[@leor2252]

Hi @KYLE.ENGINEERS , could you make a video on with the help of aerodinamics how to save fuel on Semi Truck , i wanted to see how vortex generator can help with that Thank man, ive seen couple of your videos, they're good!

[@AmsZero]

I wanted to send you this question in an email, but apparently it's business only so here is a recap: I have noticed that the roll hoop of four cars has a bar on the left side only, while five cars have it on both sides, and one car doesn't have it at all. Could you kindly provide an explanation for why such a decision was made? Shouldn't F1 cars be symmetrical? Mercedes, Mclaren, Alfa Romeo and Williams have one bar on the left, Aston Martin has nothing while the rest has 2 bars. Thanks for your time.

[@khalid26752]

Your videos are so great sir! Im doing some cfd for f1 wings, and Im facing some troubles I have a 3 elements wing, but I don't know how to calculate the planform area Should I adjust all the 3 elements to zero AoA, then taking the planform area? Or should I consider all the 3 elements as 1 indivisual wing and then taking the planform area? And if I did the second choice, should the equivalent wing be in zero AoA or what?? Please let me know

[@izumadodoesstuffinc.6917]

Hello Kyle ! I noticed that the RB19 has a smaller intake at the top of the car, do you have an hypothesis as to why ?

[@noirceur_]

This was spoken about during testing yesterday. Both the RedBull and AlphaTauri have the same roll hoop intake now, and both are powered by Honda (RBPT). Most likely Honda & RB found some performance increase with changing the size and shape of the intake. It most likely has nothing to do with overall aerodynamic performance but engine air intake performance.

[@nimalsunil8345]

You used to work at Mercedes please get back to them and design a championship winning car and help sir Lewis Hamilton to get a great farewell by winning his 8th championship. Please...... I'm saying this because I don't wanna see him leaving the spot without the 8th championship because he deserves it. He is a legend and he fought everything to become that. And he taught us that dreams are not just dreams they can be fulfilled.

[@BonoImFaded]

Hi Kyle! I would love to do the same line as work as you one day. I live in the us so education might be different here, but how high of credentials are f1 teams looking for, as I’d move across the pond to work for one Did you need a lot of previous experience? What are some qualities a team like Petronas mercedes were looking for when hiring you?

[@Leon-vx7oe]

I could imagine they did an W10 to W11 evolution. Don’t look to different at first but was a big step

[@fglespaul]

Could you do another video on the RB specifically around the ‘triple’ DRS beam wing design?

[@ltmcolen]

I have a question; we've all heard about the aerodynamics of a golf ball. Would a car benefit from having similar divots in the winglets?

[@anonymeguy9172]

Nice job ! As a beginner though I find this a bit obscure. I would be really interested on a video that come back to the basics principles of a F1 such as What do we wan't to obtain from a wing, from a sidepod, from a floor, and how to obtain it. Because it is not obvious to me why you reflect in term of vortex mainly and not that much in term of pressions. I believe that unfolding your explanations of minute details, such as you do in this video, from the basic goal of the piece studied would improve the simplicity for beginners like me. A simple example about a front wing to make it clear: We wan't load from a front wing (1), minimum drag for the load (2) and flux control (3) to pass the air around the front wheels. Thats why this shape gives load, this curve gives outwash, this winglet gives a sealing vortex that encloses the flux from this part. I don't know if this is clear, neither if this is interesting to you ahaha. Anyway Nice content and I will continue to learn from you !

[@onaweekend5138]

That RB19 could have been designed based on the head of a King Cobra snake. Quick, agile with excellent earo.

[@MrBleistiftanspitzer]

11:33 Didnˋt you mix up the flow direction several times ? Great vid overall. Will watch more.

[@joshn1678]

Kyle, can you go work for Mercedes again and show them how to design a damn car? They're embarrassing themselves.

[@seano51]

With talk now being about the drs advantage the RB has over the field, can you do a video related to aero considers when designing a drs system?

[@JustInvertedFpv]

Kyle if you ever get bored of real cars, I've been studying your videos and trying to apply what I learn to a 1/8 scale rc car I'm setting up for speed runs. In this video I got 93mph running with my full set of 3d printed aero parts. In the second run I'd broken one of my front canard wings and took them off and decided to run without them. As I hit 76mph the front lifted and I did a full on Mercedes lemans style flip. I love watching your videos! kzbin.info/www/bejne/pnjIc4qKiZebY9k

[@mukunddayaram6927]

Hi Kyle. Eureka!!! I think I have solved the aero differences between the RB 18 and W14. Mercedes are wrong with the no side pod concept because the air flow around the body is unhindered and too fast - hence the differential pressure above the floor and under the floor is less compared to the RB18 and hence less downforce. On the RB18 the side pods stick out and are undercut to form a twisting vortex as seen by the flow vis patterns in testing. It takes longer for to pass front to back - greater pressure differential and more downforce. Also the RB18 is less dragging because air going into the side pods is forced out upsides through the louvers and the hot air expands pushing airflow above the car leading to less drag at high speed. Please advise as regards your thoughts and pass on to Mercedes.😊😊

[@BuddyCorp]

Clever aussie man says plan form multiple times

[@petertimowreef9085]

The fact they've made relatively small iterative improvements on their last year's design makes me think they're gonna be killer fast this year. Though I also still believe Mercedes tiny side pods gives them advantages unavailable to other teams, if the Mercedes boffins can crystalise them.

[@alaeriia01]

Five races in: you weren't wrong.

[@petertimowreef9085]

@@alaeriia01 Fucking Adrian Newey, the man is like a cheat code.

[@FridayIncorporated]

I love your videos and I've been able to use some of your older videos to plan our endurance Champcar build. I think the motorsport community would appreciate a video on differences in drag/downforce potential between open cockpit cars like F1, BAC Mono, Radical, Lous 3-eleven, closed cockpit cars like GT Cup and Prototype, and 'convertible' race cars with windscreens like the Miata, Caterham/Lotus Seven, and Dallara Stradale. Is there a benefit or detriment between the aeroscreen in indycar and the open cockpit in F1? Further, amateur/grassroots road race cars rarely have side windows but always have a windscreen, so is there a drag benefit to being convertible like a Miata (or just removing the rear windscreen like the Visceral Racing Porsche 944 that has been very successful in Champcar)? Is there potentially a drag reduction in having a roofline or is removing the rear windscreen the only beneficial move assuming typical grassroots motorists have no driver/passenger windows? Lastly, how does a roof or lack thereof affect the downforce potential of a rear wing? Thanks for always providing such great content!

[@victorbarthelemy3993]

hi kyle thanks a lot for all these videos It would be awesome if you can make an Aerodynamics Analysis about FIA Formul E and the aerodynamic impact of cover the wheel with the front wing (sorry for my english I'm from france)

[@asterisbampos5869]

Hi Kyle can you do a video on Red Bull’s floor? I think you can explain quite easily how their floor is actually the secret to their straight line advantage.

[@x-coastie]

Hi Kyle!! Check out 9:52 of your video. What’s your take on what appears to be some sort slot on the underfloor (I guess that’s what that section of the car is) that is on the left side of the screen. It looks like theirs a opening/duct for some purpose. It looks to be 1”X6”. Thanks.

[@brucehagan]

Yeah there is a long slot there that is allowing air on the bottom to flow over the top of the floor.

[@braddick4130]

Ya, was wondering about this as well. My best guess going off of Kyle mentioning that there is significant out wash in that area. I’d imagine they are using the Venturi tunnels like Barge boards and pushing more are outboard. Only a guess though

[@shivkini9119]

Could you please do a video explaining the Mercedes double DRS system in 2012?

[@stephencawley971]

Kyle - great video as always! A question- if the FIA working group is so exercised by controlling outwash from the front wing as an aid to overtaking why are the front wings SO wide? Could they not be width-restricted to say centre line of the front tyres? This might help in curbing the levels of front wing damage we often see at races with subsequent interruptions to great wheel-to-wheel dices!

[@JB47000]

Would love to see you do some videos on the MotoGP aero devices. In the last few years the bikes have been developing the aero a lot. It’s seems like it’s much more complicated as bikes will lean 60 degrees left and right compared to only a couple of degrees or so in a car so the “downforce” is always changing direction on a bike.

[@11metalfan]

Yeah I remember we spoke about that when we had a few beers in your kitchen 👀

[@CosmicSeeker69]

Y'know I'd thought about that too - but is it really a problem since the Invisiflo (there's your marketing name) results would only be relevant to the whole aero set up of that team?

[@noirceur_]

This already exists. Mercedes used it last year. But for a majority of the aerodynamic devices they testing, the visibility to other teams doesn't matter because you have to have multiple pieces of the puzzle to put together the full image of what's occurring throughout the car.

[@dreed5965]

4:36 it’s amazing how low the car gets due to the suction where it looks lower than the 2022 car despite floor changes

The 2022 car in that picture is stationary. The difference is only 15mm I believe, in the floor edge.

[@adityapandey1329]

So you are telling me that redbull is going to win this season with just some new cardboard level parts, while othere have literally jumped philosophies. Golden.

[@Drrolfski]

Even if it's just educational guessing or speculation, you should try to give more conclusions to your analysis. It would easily double your viewers. Showing what's going on in F1 cars is one thing. But clearly explaining what it could actually mean will wake up a whole new audience.

[@staLkerhu]

Sounds good, and I would be interested too, but I believe Kyle is a man of evidence (data) and science, he often mentions what is the possible function of different details, and he also points out if he isn't sure about something, because of the lack of proper data. He is clearly not a speculator.

[@TorqueFormulaWon]

Indeed I completely agree with your assessment. Speculation is what fans and media do. This is the science explained as a best guess with the information available at the time. What can be said anyway besides this could make the car go faster. A bit blunt/ nutshell but that's the aim and only conclusion you can make/ the only thing F1 teams want to do. Go fast and win!

[@Drrolfski]

@@staLkerhu Nobody in F1, not even team engineers, is ever sure how aero changes work out until a car hits testing. And even then they're not always sure. So nobody will hold it against Kyle to give an argumented opinion on what aero solutions he suspects will work out best based on his experience. In fact, I'll bet that was often what he was paid to do at Mercedes.

[@diganic_BroxGaming]

Knew they hadn't changed the livery, didn't know it was actually identical 😂

[@dlewis9760]

They had the body wrap from last year and wouldn't have to spend some budget on it for 2023? Seriously, it's probably a minor expense, but an expense. It's possible their days of complete graphics changes while still being RB graphics are over.

[@willjackson6522]

I definitely see a little bit of Ferrari 2022 influence in those side pods. Much sharper on the lower edge and brought right out to the boundary of the size restriction.
