Why F1 Engines Won’t Work Upside Down (for our stunt)

[@Tyron95]

"Understeering like a pig" is my favourite sentence now

[@pederslothzuricho7685]

The Original RollsRoys Merlins used in the Spitfire Before being replaced by the Rolls Roys Griffons, suffered from a floating Carborator design, which meant that the Messerschimdt BF109 and the Fokerwolf FW-190's had an advantage during negative G maneuvers. This resulted in the german pilots trying to bait and evade the pursuing spitfires by going into inverted dives where the spitfire wouldn't be able to follow in a same maneuver chase. The engine would stall as the carborator's floater would disrupt the fuel flow into the the enginge. The Spitfire pilots learned to work around this disadvantage by utilizing the spitfires strengths such as turn radius in a maneuvering sequence where rolls would displace the directing of lift compared to gravity and direction of travel, to pitch into a downward spin turn losing as little air speed as possible(this is a trade off), while reconecting with German planes. Its comparable to chosing a different racing line or driving style to compensate for a style that a racing car cannot do, such as angle towards apex and entry and exit speeds. It's easy to run into debates and myths about which plane was better because it was faster or had better turn time, or even climb rates or weapon capabilities, but just as with formula 1 and indycar certain designs are good at different things, and the same goes for the pilot of a racing car as well as a fighter plane. Looking at confirmed kills also is grossly oversimplified. Enough of the history lesson, let me get to my point: Understanding what limitations keeps a standard spec F1 car in 2023 from being used in the stunt is important. But it also comes to a point where a question has to be asked: At which point is it no longer a F1 car? To which degree must the challenge be completed through the driver's use of the vehicle and when is it okay to make the modifications. Its a tough balance, but there is a limit. Otherwise, we can just lose the wheels give it wings, basically greate an airplane fly it inverted, and then claim to have driven an f1 car upside down, as long as the gears touched a tunnel ceiling. At some point you can argue if you really did drive an F1 Car upside down or not. Please don't misunderstand me, I think its a great project, and I don't whish to take anything away from you, or discourage anyone. But while some problems like an engine upside down working or not is not a first time in history thing, and its interesting history facts and all, I think its important you don't forget the mission, and when its all over are honest about the solution, when evaluating if you succeeded or not, regardless of driving a machine, upside down using speed and downforce. Which is a great project regardless of anything else. I am very excited to see how it all ends! Please don't take this as hating criticism, but just a few words for reflection. I am fully supporting the project no matter which decisions are made, I think it's awsome! If you want to know more about the spitfires engine weakness I would have reccomended a Documentary that I unfortunately cannot recall the name of, the closest and most accurate of them you can find here: kzbin.info/www/bejne/p6KsfK2aoa2EnNE.

[@NevinThinagar]

The thumbnail seems to show the normal operation of a Ferrari engine even while in the correct orientation!

[@filipkonopacki1547]

One thing I would suggest is to build an RC scale model (and a crash proof one at that) and use it to test the aerodynamics in the real world and to verify the computer modelling data. I think Scott should only attempt this stunt in person if he can successfully drive an RC model upside down in a tunnel first.

[@MrJoshsss]

Who r u why should they listen to u

[@briangc1972]

Aerodynamics do not work exactly proportional to scale. That is why if you look at the history of F1 testing you will see their scale model findings and wings did not work the same in full size cars. They also learned that running a car on a treadmill with fans blowing did not offer the same results as real world testing on track.

[@456MrPeople]

It still gives you important data though like tuning the torque vectoring system.

[@yt.personal.identification]

​@@MrJoshsssYou seem to think fame is directly proportional to intelligence. Why?

[@BeastOfSoda]

Yeah, it would need to be either a remote controlled real size car (with ballast the same weight as Scott) or a model with programmable self driving, so that the eggheads can do their own test runs and fine tune/troubleshoot in advance. But that would add extra costs to the stunt, which they're trying to contain.

Also hearing you talk about torque vectoring with a FS powertrain sounds very familiar since that's literally my job this year haha

[@LostChrononaut]

The V12 in an Messerschmitt Bf 109 was mounted in an inverted position. Just needed some clever engineering to deal with the oil situation.

[@mriguy3202]

Lots of WW@ era aircraft engines were made that way. But there were still issues with negative G's. The Germans were early to use fuel injection; that's easy, at least today. But oiling and water cooling are not so easy at all. The direction of the piston's motion is irrelevant.

[@Tobias-wb6kd]

The engines in the bf 109 werent mounted upside down, they were inverted-V engines. They still had a right way up, and would still have massive problems if under negative g for more than a few seconds.

[@ItsMe-yg4yi]

[@oldmanstumpie1061]

The video clip at 10:00 had me wondering if you are also going to be not only driving upside down but driving along the wall at 90 degress to the ground in a second run. Since you're going to all the expense and effort it would be great to see a car drive along the side of a wall where gravity is trying to make it slide down the wall. The time on its side could be even longer than the upside driving as you do not need so much length for the full 180 degree rotation of the car for upside driving.

[@tobymcnicol922]

I felt this whole project was a bit...... clickbait initially, but its getting interesting now. Even if it remains as a thought experiment, itll have been worthwhile 🤞

[@kreiseltower]

I haven't seen all the previous videos about this clip. But I'd approach this topic first by putting the car in a rotate-able drum in a wind tunnel and see how it goes when you rotate it in every sort of orientation. You could even tether the car so it can not fall far or be damaged.

[@duanezablocki8249]

Have you guys considered a 2-cycle, like a snow mobile engine? I would think they would be able to run upside down as no pool of oil is necessary. Cooling is all enclosed and not gravity fed really as long as it's full

[@zibingotaeam3716]

nah, you can't fill the cooling system until its full - then it has no room to expand and it will blow up the reservoir. You'd need to mess with the reservoir so the water pump always picks up coolant and never air, which can be done - but I doubt it's easy. An air cooled two stroke may be an easier solution to work with, but they can't do their torque steer magic with that, can they.

[@arlopaden9794]

I noticed you removed the "former" bits in terms of motorsport from the form. I did some motorport stuff at uni but then went into aviation-related aerodynamics from grad school onwards, your project sounds fun though!

[@benoitsauriol3140]

What about a snowmobile 2 stroke engine and no differential at all. The 2 stroke is relatively light, small and pack a punch for its size. It doesn't require complex lubrication systems due to the fact that it burn its oil and there's no head to lubricate. Modern engine are now injection so that systems can work upside down to. You can also use the cvt transmission of a snowmobile there's not much part to it, it's light weight, compact and effective. As for the differential you're not gonna turn all that much, therefore you would probably be better with just a 90° gearbox or a chain drivetrain like a kart. It would eliminate the risk of having wheels spin if one tire get less grip than the other and you would still be able to steer with negligeable slip of the tire

[@sebastiandierks7919]

I think you should just use the Trackmania car, it does loopings all the time and should be very well suited!

[@ApexHarvestR]

Can’t get the perfect loop with just the action keys 😂

[@joshacollins84]

I keep thinking of R/P Flip the "boat" or Research Platform that sinks partially and flips 90°. Everything on it is mounted to rotate. I am excited to see this project progress, so good luck and thank you for sharing it.

[@PhilipLeichauer]

Have worked on robotics a fair bit. Remote controll lipo could be a good solution. You should be able to get away with 20kg not 50kg total battery weight for the stunt. Have several and swap them to allow for charging. Very sensibly, split a pack into 4, where 2 or 3 sections can deliver safe power and use big diodes to link them together. Greatly reduces statistical failure rate. Happy to help if there's opportunity.

[@vaterchenfrost7481]

So the general answer to the original question "can you drive a Formula One care upside down?" is - a big fat NO! You have to build an entirely new car and an extra tunnel....who would have thought ... You could have considered a good old two-stroke engines with oil-fuel mixture - they aren't orientation sensitive. But there is still that issue with the differential, that can trow you out of yaw control. And the need for the grip is very critical here, so an all-wheel drive is almost obligatory. Those two reasons are strongly advocating towards electric propulsion. Anyhow. Without differentials between wheels and axles, and with steering of the whole axles instead of single wheels, it might have worked with a two-stroke engine within a manageable development budget.

[@DMITRIYKUSTOV]

Yeah, I’m starting to get disappointed with these series because of that. The myth is about F1 car. Now it has literally nothing to do with that 🫤 Still interesting experiment but doesn’t have anywhere enough of virality to it.

[@Jeremy-fy1sz]

[@mikebeer1567]

I said weeks ago, develope a cradle that will hold the car upside down on the tunnel, the car and cradle move along the top of the tunnel and the car is released when the speed needed is attained, mount the engine upside down in the car. This will get rid of the issues of climbing up walls of the tunnel (although not down) the issues with the engine and will shorten the tunnel needed

[@CriticoolHit]

I kind of feel like this is a stepping stone to the sort of racing we saw in the speed racer movie lol.

[@rkmbnt]

My first thought was a two stroke. Two strokes don't care about being upside down as long as you can supply the fuel, which isn't actually a big challenge with todays FI two strokes. So a couple of snowmobile two strokes and your 200kw need should easily be met.

[@_Dimon_]

Yeah, but they'll struggle to find sponsors with a stinky 2 stroke engine, can't have that in 2023.

[@FabledGentleman]

The obvious choice is to just go electric.

[@PaulTheFox1988]

It'd still have the downside of needing a way to power all four wheels, which would add more weight and complexity compared to electric. it'd be a neat idea if there was a strict requirement for it to be gasoline powered, but because there's no such requirement it wouldn't make sense to go with it when electric has so many more advantages.

[@LaggerSVK]

As someone who was involved in formula student AWD powertrain and torque vectoring I really like it. I think you can get the power and speed needed and the weight (depends mainly on battery) can go to like 64 kg for whole powertrain. (18kg motors + gearboxes, 40kg Accumulator , MCU 6kg). The main problem I see here is reliability of formula student solutions and the fact that typical torque vectoring systems are not programmed for a 3D driving so the GNSS and IMU data might get incorrectly fused. So I think you would have to design a different -> more simple Torque vectoring system solely for this job to remain straight and with the desired slip levels.

[@olivialambert4124]

My initial thought was a 2 stroke engine. It solves the oil problem as it's simply a part of the fuel, and some fuel injectors solve the fuel gravity issues. However electric simply seems a better option. I'd assume even Lithium batteries to be safer than fuel in this instance, then simpler weight and R&D makes electric the better option even before torque vectoring is considered. It's easily enough of an advantage to get past my prejudice against electric propulsion for cars.

[@ScootyPuff_Jr]

[@pierremarcoux9465]

Would there be any benefit in altering the shape of the tunnel so that, instead of driving up the left side of a tunnel, until you are driving upside down, you drive up a pitch that increases until you are upside down? I'm thinking of the Hotwheels loop, but the top portion (when the car is upside down) is elongated. That way, you don't need to worry about wheel spin / oversteer / understeer. I figure you would only need 2 - 3 seconds of upside down track to "prove" the car is driving upside down.

Battery cells have a matched discharge rate. The highest quality being those that will discharge as hard and heavy, and be done in just over 4 minutes. The length of the race. That's the right way to think. You don't need any more weight and battery, than required to get you to the end of the tunnel.

2 cycle engine air cooled. Fuel tank would be a long filled and pressurized tube, since only 4 or less liters is needed for each run. Liquid Natural gas could possibly be also.

[@jean-philippekeller7437]

you guys have not talk about 2-stroke engine in snowmobile, they can be in any dirrection and are made to be as small and light as possible, some modded engine can do around 250 HP. Maybe im wrong but i feel like it could be one of the best powertrain methode but it would requier diff and driveshaft.

[@therealnynetynyne360]

Double fuel pickups with a check ball system could solve your inverted fuel pickups problem. Combining that with a rotary

[@DanteICE]

if the engine wasn't a stress member, you could mount it in a gyro-bearing cage so it would always hang inside it vertically, I mean...it's a stupid idea, but it would work.

[@2103i]

Or use 2 stroke! Chainsaw works in every angle!

[@KyleMc16]

And then the engine just spins around in the cage instead of turning the tires.

[@DanteICE]

@@KyleMc16HAHAHA very good point. At least I said it was a stupid idea, I think I covered myself. I'm going to claim I was drinking at the time 😂

[@gameexe6337]

sure a continuous sustained upsidedown wouldnt work but i dont see any reason why this wouldnt work for just a few seconds that it would take , not like a few seconds without oil will kill it

[@cynic5581]

F1 engine would be lucky to last 1 second starved of oil without seizing up. Incredibly tight tolerances plus insanely high RPM doesn’t bode well. He wants to drive upside down for 5 seconds. That’s up to 1,600 revolution the engine will need to do completely starved of oil (20k rpm / 60 x 5). Even if it didn’t suffer a catastrophic failure it can’t even vary its power outlet (thus speed) over the course of being inverted.

The animation at 10:42 is really interesting, never saw that before.

[@grand24able]

OH yess! Keep them coming

[@Inertia888]

This reminds me of the powertrain and PID controller of Quadcopters, but power output at wheels, instead of propellers.

[@joshmaynard1505]

I'm only 5 seconds in but I'm still going to have my say. What about a radial engine? Or rotary?

[@Hello_there_obi]

I think making the engine work upside down would have been much more impressive, emotive and thrilling to listen to. It’s a shame imo. Ev seems the easy way out!

[@oscarmollenhauer3083]

Why don’t you use a regular loop de loop, with a flat extension at the top in the middle? It would be much easier than trying to turn up a wall, and you wouldn’t have the issue of 2 wheels being off the ground.

[@TrevorDennis100]

This would make an excellent book, which might also help with the funding.

[@coin777]

Maybe don't use full battery of a Tesla that gives 500km range if you need 5km range.

[@asherrose4114]

2 stroke motor, fuel injected with a round, pressurised fuel tank. Regardless of orientation, this would work. Or a fuel tank with a pick up at the bottom and one at the top, gyroscope type sensor activated pickups would mean fuel is always been fed regardless of orientation

[@AlexBarker11]

You could also do a cylindrical fuel tank with the pickup coming directly from the center axis and the whole internal sending unit would be on a swivel fitting so that it would settle to whatever angle becomes the bottom
