Why didn’t Max’s DRS work this weekend?
So Max took the win in Spain, but the race was far from plain sailing. He went off at Turn 4 after a big gust of wind took away all of his rear downforce, then his DRS wasn’t working (apart from when it did) and then Red Bull had Checo get out the way.
But the DRS is the most interesting bit about all of this, because it seems like it should be something the team should be on top of. And Max made his frustration about it well-known.
So what went on? Well, Scarbs has a very good theory about which components are causing all of this.
So, even from qualifying - the DRS was posing an issue on Max’s car. On his final lap in Q3 - one that could have been for pole, his DRS didn’t open.
But it turns out, even despite this, the Red Bull is so fast in a straight line that it didn’t (lose) time on the straights - just didn’t gain any either.

RB Engineer: DRS worked last lap. YEAH BECAUSE I ****** PRESSED THE BUTTON 50 TIMES
"OK max just one press after the kerbs" shit killed me lmao
》Max press it only Once, and after you rode the Curbs《
Max: Still Opens it on the Curbs and 50 Times....
JP: 😐
@@wes4990 😂😂
Couldn't operate the DRS coz he was rattled by Russell 🤣
I thought Drs was automatic. Didn't know the driver has to press a button
Best Spain race in a long time with all of the shenanigans
These 2022 cars have made for some great racing, even if they aren't the best cars we've seen in F1. The parity is much closer.
Yeah I mean they perform best in high speed corners 150+ like at Jeddah they looked very fast but they are slow in slow corners so Monaco will be a lot slower than last year probably by around 3.5 seconds
@@bean2705 Ugh I'm not looking forward to Monaco. The one track that NEEDS to be updated, and the one track that never will.
I think it means that midfield cars pretty much stand less chance at getting wins and podiums compared to before because it's so much harder to use dirty air to defend. The racing itself however, is absolutely better. No contest.
@@GoingRampant92 The track is fine for the most part, as F3 and FE demonstrated. F1 cars just need to lose mass and volume.
@@F1ll1nTh3Blanks Either way, F1 doesn't run well at the circuit anymore. the cars arn't going to be getting smaller anytime soon, so It's a bit of a problem that doesn't have a perfect solution. As you've said the other formula series can run there just fine. I don't think it's the layout that needs updating, She's just not thick enough for the cars now.
What surprises me is that nobody is mentioning that the flap opened but closed right away, several times. If the wing was jammed, it wouldn't have opened and closed that quickly. My guess is that it's an electrical issue, similar to shift syncing, where the car doesn't have the right data. It worked fine on other parts and did sort of work on the straight a few times.
Totally agree. The assessment that it was binding is nonsensical.
Not only that, it did stay open in the other, shorter DRS zone. It's an odd problem but i have no doubt RB will figure it out before Monaco.
My thoughts exactly. Both are talking out their rear end here.
I couldn’t help but thinking that maybe it was the airspeed forcing it shut again, not that I have an intricate knowledge of its workings, but it just seemed to open initially and slam shut again
You could see in live telemetry that Max’s DRS was ‘opening’ and ‘closing’ many times during a single straight. It basically looked like morse code.
But irl, his wing didn’t respond in the same way. Either staying closed, open, or opening and immediately closing again one time per DRS zone.
Really seems like it was an electrical issue. The data being sent from the car wasn’t what the car was doing at all.
Lap times after Max pitted…
Lap 46
Checo: 1:26.808
Max: 1:25.456
Lap 47
Checo: 1:27.183
Max: 1:25.704
Lap 48
Checo: 1:26.915
Max: 1:25.755
Lap 49
The switch happened. The switch was necessary. No use letting them fight it out when there’s a round of pitstops left. And they released Checo when he was faster too, people are making a mountain out of a molehill.
Exactly and imagine crashing both cars when you're fighting it out. Especially considering how RB would lead both Championships with a good result there. People just wanna talk shit that's all
Shoot, they don't even need to fix it for Monaco 😆
Monaco has a drs zone right?
@@CazAlt Yea but its so short that it does nothing lol
Everybody forgetting that DRS worked on back straight flawlessly.
Definitely something with aerodynamics and wind. From what I observed, DRS was opening and then shutting again immediately. Perhaps back wing setup was adding to the issue, as Perez with different wing had no problems.
Yeah, how can the pins be guilty
I saw somewhere it was due to the weight reduction
That’s what I was thinking also. Plus, binding pins wouldn’t explain it opening, and then slamming shut. Not buying the pins theory!
Could be, they reduced the size of the piston,that pulls the flap open, to reduce weight. It could have had the knock on effect of reducing the available mechanical pull to open the wing
This was not the case in my opinion.
Having watched the race I think its something else.
Either electronic or hydraulic.
The flap DID open most of the time, and then suddenly close immediately after.
If it was just too much "binding" as this guy says, then it would either have the "force" to open or not. But ONCE IT'S OPEN, why would it close again ?
That means that EITHER the hydraulic actuator lost pressure, or wasn't strong enough, OR, the electronics were failing and gave the actual hydraulic solenoid controlling it the command to close.
There was a board radio where Max said something about the flap opening and closing again, followed by something as "I pressed the button **** 50 times", to which his engineer replied he should only press once, after the final kerb. This implies that pressing the button more than once (and actually an even number of times) could cause it to open and then close again, sinds on the first press it opens and on the next it closes. That would also fair pretty well with the statements from the video.
@@roelfo It was his engineer saying something like 'we think last time you closed the flap yourself', to which max responded with the '50 ***** times' comment.
other then that, spot on.
@@TheCountess666 thanks for the little correction!
I love how the wind can just Thanos snap cars off the track
Knowing that they could, theoretically, run upside down in a tunnel thanks to their formidable downforce I am a bit confused 👀
@@zippo5294 Its probably because the wind is coming at an angle so it throws the cars balance. Also when a racing car turns sideways against the wind it can be a lot dangerous, they act like an airplane wing and can produce lift.
I think perhaps a sudden strong gust of tailwind would decrease the downforce and make the rear end lighter. 30 mph would effectively decrease the airflow over the wing by that amount.
@@zippo5294 because he turned in at the same time, drive a Simulator and you will learn that the rear likes to go all the time if you are not really gentle. And that wind wasnt gentle at all.
Makes sens! Thanks for the explanation guys!
All of the top teams have been suffering reliability issues this season. This is the first year with new rules and the cost cap. It appears to me that the big teams are struggling with the cost cap and are sacrificing quality which is leading to reliability issues. Whereas in the past they would have thrown loads of money and done loads of testing on stuff now they are rushing it onto the cars.
It does make it more exciting when you aren't sure if the cars are going to finish or not!
Engine un-reliability is partially planned. The engines themselves are frozen for 4 years, but all the manufacturers are allowed to make changes that benefit reliability only.
Therefore, it’s much better to make an extremely powerful, but fragile engine for this year, and then tweak it to add reliability as the season goes on.
That way, you’ve got maximum power for the next 3 season after this one.
I think it's also part of the aggressive weight saving measures all the teams are going to
To be honest. The Honda engine has been reliable so far. The fuel pump issues are not power unit related.
One of the issue is the fact that a large portion of those parts are getting replaced for lighter ones for weight reduction therefor may be fairly new.
@@Lanse1984 Not really. Gasly has had numerous MGU-K problems this year. Checo had a sensor issue on the power unit only last race. They’re all fairly similar. Ferrari have had issues with the Alfa engines. Aston and maybe McLaren have had issues with the Mercedes engine and Alonso has been through quite a few engines as well!
@@Lanse1984 Just had a look. Yuki and Gasly are both on their third (and final engines) already. Perez is on his second turbocharger and second MGU-H. Gasly and Yuki are on their third turbos, third MGU-H and third MGU-K.
I think, it could also be the wind. It was pretty windy that day anyway and right before the start they showed the flags indicating that there was a pretty strong headwind coming towards the drivers on the start/finish straight. And since the upgrades saved some weight, they might've also used some weaker/lighter parts for their DRS. And if you test it in the lab under Vmax conditions and maybe a bit over it, everything seems fine. But if you add some strong headwind, the DRS system then might simply be too weak to actually be able to lift the flap properly and it fails. Physics could've been the problem.
hahahaha another couch engineer from his mom's basement
This seems more likely to me since you could see the flap open and close rapidly many times. Also would explain why it was so intermittent. I suspect the system doesn't have hydraulic pressure on the actuator for the whole time the wing is open, but is instead designed to open the wing with a pulse of pressure and then lock it in place mechanically.
I thought it was the wind. The DRS also always worked in the second DRS zone, but not the zone that had the most powerful headwind.
Checo didn't had this problem tho
@@NexuJin Checo could have had an older spec. They’ve got a clear number 1 and number 2 driver. With the budget cap, maybe it’s better to mainly bring updates to Max’s car.
I think he had some problem with the pulling mechanism which when put under load of main straight and headwind was unable to either open or keep the rear wing open and with no head wind and lesser load on the back straight drs zone it was working well
That’s what I was thinking, that it was the hydraulics fighting against the air speed somehow
I am pretty sure closing it would be under load, not opening it. The air is trying to push it open , right?
@@StingrayOfficial are you sure pushes at the rear wing that drag generates and when it is angled the air pushed up pushes it down at same angle thats how downgorce generates....DRS i.e drag reduction means to reduce the surface of the rear wing by allowing the air to flow through it when opened....so i don't see how it is pulling it open
They were replacing parts on this area during last year. This isnt a new problem! How many times did they go into park ferme and change rear wing components in 2021?
Countless. I think it is even very dangerous during the race. Last year I remember a race where their DRS won't close (the opposite of yesterday).
@@IHaveTheAmbition the fail state is closed. When/how did it get stuck open?
@@IHaveTheAmbition it didn't stay open, if that happens you spin at the corner and end at the barrier. It kept opening and closing very quickly the entire straight, it wasn't dangerous but made the Red Bull lose time. Happened in a few races at the end of last year.
That is allowed when something is broken, but it is NOT allowed to replace with other specs. The replacing parts need to be the same specs.
@@scottgunther2021 there was a practice session last year it got stuck open and they had to fix it before qualifying.
A good aerodynamics engineer would point out that the pivot/hinge point should be in the center where the force of drag is balanced between open and close, not the back. Thus could decrease the force required by over 90%.
As i thought
That would rotate the rear half of the flap into the wake of the first wing element.
That alone would try and close the flap because the air would be pushing upwards at the rear. It would also slow down the air in that region and create a high pressure build up over the wing. Lots more drag
You want to bring the DRS flap up and as far away from the lower wing element as possible. Hence the pivot point high at the back
That was my first though too but the geometry requirements discourage that. It's more likely that parts are deflecting under load. The three pivot points are no longer in line and causing the system to bind up. Slow down and it goes back into line.
PS if its into a head wind that's a lot of extra load. The load is the square of the velocity.
Of course the F1 engineers did that way because they aren't good enough.
Sorry, I dont know half as much about engenering but I don't think its the pins. A couple of times the rear wing opened fully for a split second and then closed again. So I don't think it can be stuck pins.
1st video I’ve seen that actually just went over the RB issue and said it’s a simple fix. Props to you for just not automatically putting out RB hate and being objective
To me watching it live, it's almost like the line going to the wing wasn't getting enough hydraulic pressure. If I were his engineer, I would have told him don't open the DRS after turn 9 onto the mini DRS straight and to save it for the main straight. It's almost like it didn't have the pressure to open twice per lap.
I think it's all about sensors connected to DRS
Thank you so much for this type of approach to sponsors. I really enjoyed this video
I assumed Heston Blumenthal knew something about flapjacks, I didn't know he knew so much about flaps aswell.
underrated comment
He knows about burning people's stomachs out.
I did. I caused the DRS failure. I went full Solid Snake and sabotaged Red Bull. All I had to do was wear an Aston Martin outfit and say "I'm looking to buy aero designs".
Mercury was in retrograde, thats what caused it.
Excellent!
✨️ insane ✨️
When the pins were binding, how come the DRS opened and closed immediately afterwards? If it was stuck it wouldn't open at all.
Because Max was pressing the button multiple times, and pressing the button again closes the DRS. There was a radio conversation where his race engineer told him to only press it once
@@Netrole Lol makes sense, he was quite agitated about it so if it was me i'd be pressing it multiple times as well
@@Netrole but if he was pushing it multiple times, wouldn't it have opened and closed multiple times? Or is it a "once it is closed, that's it" kind of situation?
As always, the journalism here is on point. Unlike Autosport where they blamed Sainz and Verstappen for their turn four incidents claiming those were errors and not any sort of gust and wind.
they were driver mistakes though, you can’t deny it
"arts status as a physical asset means it can resist inflation, maybe even more than a savings account"
yeah so hard to beat out a 0.2% interest rate lmao. masterworks sounds like such a scam
Don't put money in banks, they will control you like a puppet, getting robbed in house is better then getting robbed in a "secure place"
Yeah I heard that and thought, "Lol.. cause houses or cars value can never go down right... or gold, or literally anything else." Art is already a scam.
but the wing flap did open on the straight, but then promptly closed again afterwards; binding doesn't make a lot of sense. I remember Max had DRS issues last year in practice or qualy at Zandvoort as well. seems like a recurring issue for RBR
in one of the official F1 videos (qualifying highlights i think) you can hear max and his engineer talking about that, with the engineer saying that they think max closed the DRS himself last time, to which max angerly replies 'cause I'm pressing it 50 ******** times'. they then instruct him to only press it once.
I wonder how much the DRS got affected after Max went off into the gravel. Also it doesn't make sense if the pins were too tight. That means that the flaps would either not open or open and not shut. During the race there were numerous times when the flap opened but immediately shut. I'm guessing something got loosened rather than the pins making the wing too tight.
As so many comments here have said, the flap opened then closed immediately several times. It wasn't stuck or it would never open. It was also only on the main straight as best as I can remember.
Tells me thats an actuator issue.... ooen but can over ride the force of the air
great Video as always! would love to see a video on what happens when an engine overheats, like charles' did. it obviously didn't blow up so I wonder what ultimately caused his dnf and how it affected the car
❤
It would be hard for them to pin point that exactly from a viewers perspective
Max vs Charles at Monaco for poll is gonna be amazing
The DRS is handled remotely based on timing right? I thought there may be some wireless connectivity issues around the circuit, other drivers were having issues earlier and some of the driver cameras weren't working at times
That occurred to me as well. Sergio had no problem.
Isn't DRS designed in a way that it wil automatically close if there is a failure.
I think the flap closing was the downward pressure of the lifted wingflap closing the system again with the added weight of headwind
Redbull had DRS issues last season as well. I remember a slow motion clip from last year when the rear wing plate was flapping open and closed all the time.
Why are you so sure it is a mechanical issue? Because they replaced the parts after qualifying? Could be preventative.
I'd say it could well be an electrical issue. Maybe the DRS button activated/deactivated very fast over the kerbs, and the driver would not know if DRS was activated or not. Then pressing might deactivate DRS. A couple of times, Max is seen to very quickly open, then close DRS again. This suggests that the driver can actually deactivate DRS while it is open. Which is a very silly idea to implement unless it is specifically stated in the rules that it should be a toggle.
I saw in the race that in the other DRS zone Max had NO issue at all with DRS. Only on the long straight.
And on that straight they had a headwind. Also opening the drs with higher starting airspeed (because of the head wind)
May be the DRS could not handle that extra force on the wing.
When Max fell back from Rus on the main straight it also worked, it was only when he got within about 8 tenths it didn’t work.
The DRS zone 1 was at a higher speed I thought, not sure the wind was that strong to make the difference. Very bizarre though I hope we find out.
personally, I think that because it was so hot on that day the pins on the wing had expanded due to the heat, therefore causing the binding.
ahahahah another couch engineer
@@addipoom i mean his answer is kind of valid
@@addipoom anyone can poke fun of another, tell us what you think happened? You may be educated but you are ignorant 😉
@@that_ls1_guy95 It isn't even remotely valid. Nor is the idiocy in this video. If the problem was binding, why did the flap open and immediately close multiple times? These idiots are acting like it wouldn't open, but it clearly opened and closed instantly on a couple of visible occasions.
@@addipoom of lord. We all are, aren't we? 😆😆
Red Bull has already announced that for the Monaco GP, they will reverse the weight-saving changes made on their DRS. These were installed only on Max's car during the Spanish GP.
Red bull confirmed it was related to weight saving on Max car. Perez didn't have the same issue cos he didn't get the same update. They said they will reverse the update for Monaco. So Scarbs spot on
Seemed to be happening on the main straight in the head wind and seldom on the back straight in the tail wind. Definitely intermittent as well. Definitely not Max's fault (I don't think the curbs played a role if I'm honest, I think when they said that they were perhaps thinking electrical intermittent behaviour) . He ran a big wing and was banking on that thing working. It seemed to open and then shut again immediately to me. I reckon Scarbs is on the right track and it's mechanical for sure but I think perhaps the wind loads also contributed in the two different sectors where it was used. So that pressure of the headwind needed to be overcome to open it and have it stay open and the system just couldn't cope with it most times. Whereas on the back straight it could just about manage it on most occasions from what I could see. On that back straight you could argue that it's a very different curb layout on the exit to turn 7 or 8 I think it is the blind right hander at high speed onto the back straight. But I'm not convinced because Max purposely stayed off the final turns curbs on exit to test that and it didn't really help at all.
wait but on the shorter DRS zone the flap was opening properly ...
Maybe that was due to there being less crosswinds?
@@juliettacharlotte also, not always :)
Scarbs is the goat. He gives us better knowledge of what's going on than sky
His DRS was working in the other DRS zone though? So I would have thought if it was binding or other mechanical failure it would be presented in the other DRS zone as well.
I'm here for the DRS video, but the eye candy is an added bonus. Callum, you fine as hell.
@Driver61 could you please make a youtube video explaining what tailwind is? The commentators mentioned about it when max & carlos spun their cars.
Well done for not having background music blaring out. However. It is still a distraction and halfway through I am clicking away because I cannot focus on what is being said. Think tinnitus.
I dont know about your explanation but I believe that the problem lies with the gremlin holding the wing open on the inside.
I would think about some sort of fault in the "sensor" that tells the DRSto close.. i think it closes when pressing the breaks ..
I dont buy the binding theory. Sometimes it would pop open for a second and then immediately slam back down. My guess is the actuator
It was a pretty funny situation like every time Max was close enough his DRS didn't work and when he was a few meter too far behind the DRS worked, lol.
But if Russell hadn't defended that well he would probably been able to overtake the times the DRS worked even if he was a few meter too far behind since the RB had much more grip. And Russell defended exactly on the limit to what could be seen as illegal defending, imo.
This does not seem to add up. The drs seemed to flip open but then close straight away. If the pins were stuck this wouldn’t happen. Probably the actuator or hydrolics were broken, causing the drs to flip again.
theres a lot of good, logical explanations in the comments. i think , personally, if the kit works ok at the factory, then the issue local. track, fitting, heat etc. or quite possibily, signal interference/ attenuation. It's interesting to note that Checo didn't have such problems. i'm going put put my 50 pence bet that max car is running 'experimental' optimisations in terms of fly by wire. such as pre-opening DRS by fractions of a second. or it's NSA /GCHQ got the receive and transmit signals back to front lol
The hydraulic (!) cilinder should have no problem opening. In fact it did but 'decided' to close again. There must be a sensor that receives signals from the racetrack itself that allows it to be open and stay open. If the, probably radio signal, is not well received or sensitive to interference, by this sensor on the car it might report to the DRS subsystem that there is 'no permission'. It is just guessing how this could work and thus not work. But I cannot believe in the theory by Scarbs that it has anything to do with shaving off material of parts in order to get right of weight. That would be difficult to implement on this part and also I believe from faint memory that this cilinder is the same on on all cars and therefor cannot be modified due to regulations. (Otherwise it was the wind ;) as Max and Carlos stated)
The problem is weight reduction. This makes parts like the wing less reliable and add to the mix a high downforce package this week compared to previous setups, the down force and pressure on the wing is able to over come the power of the actuator that opens the wing. This hasn’t been an issue because RB has been running low down force packages. The weight reduction is a bigger issue on Max car because Parts on Max car are lighter than some on Sergio’s car because Max is a bigger person. This explains why Sergio’s wing didn’t have issues.
No mention on why the wing always worked in the second DRS zone, but not within the first DRS zone?
Exactly this. If the problem was mechanical why didn't it happen here? I think it was an electrical issue with a sensor or something.
Cheers from the Pacific West Coast of Canada.
This looked to me to be more of an electrical issue. The flap would open, but then immediately close. Perhaps the physical button on the steering wheel or an intermittent ground or other connection issue.
That race proves DRS is needed in F1.
Im not sure that what they are saying is correct, certain instances DRS flap would open and then quickly shut again. Doing this does not sound like a binding issue as it would not open at all.
Maybe different vibrations, wind directions, wind strength, etc, changed the conditions enough to work where it did. Bouncing on a kerb could either shake it loose or make it stick for instance. So many mechanical forces are in play on an F1 car so I think maybe not even the superior RUclips Comment Section Engineers have all the answers 😊 (I'm not poking fun at you specifically, but there are quite a few self promoted F1 tech experts here 😁)
Max's DRS:
What about Max's tour through the turn 4 gravel? Maybe dirt got stuck in the DRS.
Max and Red Bull were very lucky that Charles had a DNF, and Carlos Saint had a bad day.
i actually might disagree with scarbs here. GP kept asking max to only hit the drs button once, and then asked him to hit it once only after he had gotten off the kerbs. while scarbs definitely is on to something, i think what might be (also) happening is whatever Red Bull is using to debounce the drs button has broken.
I also lean towards it being an electrical problem.
And after Max was told to only press it once, and he did, the flap opened then closed immediately.
Multiple instances of DRS opening and then immediately closing seems to make the explanation that pins stopped it from opening unlikely to be accurate, IMO.
I’m not sure this is a binding problem like this video says. Many times the wing opened and immediately closed again. Was that Max pressing button too many times or was it an intermittent control issue? More info needed, but we’ll probably never know.
That's what I thought too, or a faulty sensor for the automatic closing on throttle lift/braking. They would surely put a scope on it and see if there was a noisy signal though, so perhaps not.
Watching the race I was thinking it looked like an electrical issue. The button signals the system to open the wing, the brakes signal it to close. If the system is getting a faulty signal that the brakes are applied, the system wouldn't open the wing. If the brakes appear released when he presses the button, and then appear applied just after, it would open & close. My guess is that you can't just fail the brake sensor out of the system, or the wing wouldn't close going into turn 1. I remember a race last year at a track that had a long straight without a DRS zone, Brundle saying they couldn't put DRS there because the curve at the end is taken flat-out, and the wing wouldn't close.
Did they check if it was a fault on Max's steering wheel button (electronic/mechanical) rather than a mechanical issue on the DRS mechanism itself?
But why were there no issues on the other straight? Could it be an error with detection?
Adrian Newey said in an interview with Nathalie Pinkham and Alexander Wurz, it had nothing to do with weightsaving!
Why did his drs open EVERY TIME between turns 9 & 10 but fail down the start /finish straight? My theory is, with the head wind down the start/finish straight, it was slamming the flap down and the mechanism couldn't hold up.
They always have problems with wind at turn 3 and 4 at Catalunya. It even affects MotoGP too now they put wings on the bikes, but not as seriously as to make them crash.
The comment about pressing after the kerbing was to eliminate the possibility that Max pressed the button twice while moving in the car. Pressing the button again while open would close it.
Can't quite see what scarbs said as being the problem. The fact it was happening every other lap perhaps points to software issues instead.
Be interesting to see what rbr finds out
That would explain the flap not opening but a few times the flap would open properly and close immediately?
I cant believe the issue is simply binding. How does binding allow an actuator to properly open the DRS part of the wing & close it again 1/4 of a second later. I cant be the only one who saw the DRS was working a lot of the time but only for a split second. There is more to this issue.
Tje trick of tje gusty winds is they are real cheap with downforce only using as little as they can get away witj so the car will be fastest in a long straigthaway
Speaking from an engineering point of view i would guess at the frame that holds the flap is flexing undet the aero pressure of speeds exceeding 160...mph..
Imagine a frame to thin as the wind push it squeezes the spoiler flap locks it inti the frame do to flexing an contorting the pins are pivot points doubtfull they would cause sufficiant binding...like a 360 degree frame mite...those pins were checked by stsndard an peers to be dead on balls accurate....by vinnie girl friend
Those explanations don't explain why the DRS shut shortly after opening on several occasions.
After a GP finish, i wait for Peter Windsor's take. Then i wait a few more day for Driver61!
I wondered if Verstappen's DRS actuator simply wasn't strong enough to keep the flap open with the headwind on the main straight. If Red Bull is designing the actuator to have just enough strength to open the wing in normal conditions, I wonder if the binding you mention, combined with the added load that a large Barcelona rear wing would've entailed meant that the actuator wasn't able to reliably hold the wing open. Binding doesn't seem like the only factor to me, since the DRS would reliably work on the short back straight. The wind I feel is the main reason that the system wouldn't reliably work down the pit straight.
Could it be that the combined conditions made it that the force exerted on it were simply more than the actuator was meant to handle or could the components have been faulty?
The numbers below are all imaginary, I just want to illustrate my point.
-The Red Bull DRS actuator provides 200N of force to open the Rear wing
-A RB18 In regular trim with a normal wing, assuming standard atmospheric conditions requires 150N to reliably actuate the DRS
Then, let's look at the factors I think might be at play for Max in Barcelona:
-Larger rear wing: +20N (larger wing weighs more, and also generates more downforce which means it requires more force to open)
-Headwind: anywhere from +10N to +30N (the intensity of the wing changed quite a bit from lap to lap)
-Binding, excess friction, poor component fit or warping: anywhere from +5N to +15N (this can vary from lap to lap, and might be worsened if the car is being jarred by running on the kerbs)
So, if the Red Bull usually has 50N of excess force in normal circumstances, this becomes 30N once the larger than average rear wing gets fitted. That 30N of reserve might simply not be enough to reliably open the wing when the wind is blowing especially strong, or when the parts in the rear wing assembly are being especially troublesome.
Another possibility that I simply cannot comment on further is that there was some sort of electronic fault that convinced the system it needed to close the DRS flap on the main straight, but was completely absent when Verstappen was on the back straight.
This explanation doesn’t make sense. In the video you saw the flap open and then close again. So it wasn’t just not opening because of some binding. It was opening and then something was causing it to close again.
Whatever it was.. Sure is that at this moment there is a DRS flap opening/closing 24/7 in Milton Keynes.
Seems most likely an electrical failure than idraulic.
I have a question: why drs is an idraulic system and not pneumatic/vacuum system?
I wonder if red bull isn't overflexing their rear wing.
That would certainly put more pressure on the mechanism and pins
@@mbal4052 and their straight speed even without drs
Actually is quite entertaining to watch without DRS in race just like old times, perhaps FIA needs to limit only 1 or maybe 0 DRS for all tracks. it would be interesting to watch certain tracks only has 1, certain tracks has 0 DRS
Im gonna say that the extreme heat, coupled with the already hot car, caused the hydraulic fluid to lose its viscosity, becoming more like water than hydraulic fluid, therefore not having enough pushing power available
But the same would have happened to Perez and some few other driver though
Then why did the flap open and close immediately multiple times? It wasn't an issue of lack of power or binding, or it wouldn't have opened in the first place. This video is pure nonsense, from someone who apparently didn't bother to watch the actual race.
The window crank to the drs in the cockpit was broken.......
Doesn’t explain the times where it opened for a split second before shutting again though…
This host is better than the other host.
It could not be the pins were binding because it would open and then snap shut.
If it was binding cause of weight saving why did it only affect Max's car. Didn't they do the same weight saving on both cars?
Several times I saw DRS opening and immediately closing... how to explain that?
My TV was almost as broken as the DRS on the car.
It’s hard to imagine that a race car at speed is going to be that affected by a tailwind.
Even a 747 can be drastically affected by a tailwind …
@@sking2173 Yes it can… a tailwind makes the jet travel faster.
@@OldStreetDoc - And if that tailwind component is in the form of a gust, the 747 wing will suddenly lose some lift, just as a gust wind can do to the wing on the F1 car (lose of negative lift).
Yeah, wind can ruin things. I remember on a date once, when wind created a real problem. lol poooot
Well now the ones who previously said DRS is OP... Pretty sure no DRS at all is worse. Barely possible to overtake
You didn’t once talk about nor show MV’s DRS open and quickly close. I saw it do that at lease twice in my feed. I find your “theory” bogus after seeing this happen.
This is only speculation. But my oh my, some mighty good speculation.
Max's DRS opened all the time, but closed immediately again most of the time. So, it just was not securing.
Could it have come from him spamming the button?
@@adamozmin8970 but he wouldn’t have spammed the button if it stayed open after the first time
Ella Schnee yes but the problem was intermittent, sometimes it opened sometimes it didn’t and when it flipped open and shut quickly which is what Ronald de Rooij was saying. Could that have been from spamming?
@@adamozmin8970 that could be true, but only if it didn’t open in the first attempt or maybe a bit delayed? So I don’t think at all that him spamming it was the primary issue there
Rb can get away with this in monaco but they should get in top of it before baku.Imagine that redbull in the main straight at baku.
Hmmm, this seems a bit obvious to me. after he went in the gravel he had erratic problems. Because of an odd bit a gravel jamming things up, which eventaully wore out / fell out. And now no one can find a good reason. John Hancock
As Boris the Blade said “heavy is strong, nearby is reliable”
I don't know about everyone else, but I'm having a hard time troubleshooting Max's drs without actually having the data and the car to look at.
shirley, nobody might have a directional emp device.
