    I’m going to drive a FORMULA car upside down in a tunnel. BUT, as I said in the last video, we know an F1 car isn’t right for Project Inversion.
    This is the story of how we found the perfect car to drive upside down, how we made it produce more downforce than an F1 car and how we overcame a multitude of design problems, many of which you might not have thought about.
    But first, a bit more on why F1 cars aren’t right for this crazy stunt, and how much downforce, relative to the car’s mass, do we actually need to create?

      If the ground car is bigger and has some sort of landing pad with heavy feathers below, it could increase safety by providing a little softer landing (probably still brutal, but it might help reduce the stress on critical components) and by preventing the unintentional abuse of the upsidedown brakeing system

    I still think that starting with the car inverted is the most realistic approach (though could be considered a bit cheeky). Install the car on the ceiling on a track and essentially keep it tethered until it gains enough velocity to generate the required downforce, then have the track end and allow the driver to do their thing. Heck for safety you could always keep a loose tether attached so that if a mechanical or electrical failure occurs it’ll keep the car and driver from certain catastrophe.

  • @PlaySA
    @PlaySA 7 місяців тому +8

    A SUPER crazy option would be to still include ground effect downforce, and make the ENTIRE tunnel/tube the same circumference. So that even on the bottom it's still curved. Then design the car's floor so that it descends to follow that curve perfectly. That would be wild

    This is so exciting, super cool project!
    To avoid that danger zone diagonal angle riding up the wall where the front tire can lift up to 10cm, why do you not use four wheel steering, but the rear wheels are reversed? That would keep the car straight and parallel to the tunnel to keep the optimal downforce and grip.
    Second thought, why isn't the belly of the car also rounded of to keep it closer to the wall of the tunnel? sure it would beach it self on any normal flat road, but you are already building a custom vehicle with it's only purpose to drive in a tunnel, so why not also modify the whole under side and diffuser of the car to fit the shape of the tunnel?

      The car is already custom enough to not be any normal or regulated car, but money and complexity sure plays a part in the design, just feels like something all these engineers would have thought of and would be interesting to hear why not.

      I'm imagining a curve to the left as you drive counter-clockwise to go upside down. Would this curve only help you reach the half-way point where you are perpendicular to the ground though? You'd have to curve it 'down' for the centrifugal force to act in the direction of transitioning from perpendicular to upside down.

    • @felixproger
      @felixproger 7 місяців тому

      Seems feasible, and some racing tracks already have a good slope on curves, mainly oval circuits. It might even be a start point for the construction. (Thoughts from an IT student, so dont bet your lives on it)

    • @Hamring
      @Hamring 7 місяців тому +3

      interesting point. Intuitively it seems like doing this could also help stabilize the construction as a whole. At least in the actual curved section. I'm assuming the greatest forces will be occurring in this transitional phase of the drive. An issue with this might be cost producing this additional curve in the C shaped elements. I'm not sure if they are planning to use custom made elements or if something suitable already exists, in which case this would probably also help keep costs down.
      Another question i have is how the wind will interact with this construction as a whole. With the smooth shape required, it seems like even slow wind in the right direction could compound quite dramatically in different ways along its length. They do mention winds so I assume they have considered this but it is just another element among so many.
      Personally I'm not an engineer or anything of the sort, but i am interested in these things and do love running scenarios like these as thought experiments in my head and it will be truly fascinating to see something like this come to life as an actual practical experiment! The way I see it its such a pure example of human curiosity and spirit and I love it!

    I'm concerned about the steering issues you'll encounter when trying to fit the camber to the tunnel's radius. Turning slightly may cause instant and uncontrollable oversteer wouldn't it? it would be like having one front wheel suddenly have a toe-in and the other a toe-out setup.

    Limit the dangerous transition to just the end of the run. Hang the car in upside down mode from start using a t hook on bearing on an anchored track. At optimal speed, disengage t hook and drive on ceiling for a bit. Then , on exit in order to compensate for "peeling" , use centripedal force to transition the end of track which can have a inward curve in 2 directions (east west and north south simultaneously) a smoother, safer transition for the final xyz axis segment.

    How are you starting, is it on a normal road then you transition into the tunnel?
    I know the sponsors will love this idea 😁
    Would it be better if you made a runway the same curve as tunnel and make the underneath of the car fit the curve better.
    Also at first I kept thinking about the air density if your running the car in the tunnel a few times how much hotter and less dense is the air at the top but that's probably negligible to the amount of force the car will be producing.
    but also how do you choose the tyres? If there are cold spots on the tunnel surface and some hot spots, more likely on the top, does the hardness of the tyre come into it?

      The problem would be actually following that path. If anything goes even slightly wrong and the car drifts off course, it no longer has that optimal geometry under it.
      It's safer to optimize the car for a uniformly circular tunnel, that way there's a lot more room for error.

Think like the rotating corridor in the movie Inception. A big rotating drum with a bridge running through the middle of it that can be flipped over.
      Edit: Actually, there's a much easier way: A loop. A long stretch of road, a half-pipe ramp, and an inverted stretch of road directly above the run-up stretch, with an exit ramp that connects back to the run-up section... No corkscrewing motion, just ride it straight up like a rollercoaster.

    The biggest problem will be getting the suspension to handle the opposite corners ride height problem when angling on a tunnel, while also handling a massive load difference.

    This all seems very thought out luckily and it seems like it’s going to work. The only thing I’d be concerned by now is the G-force created by the centrifugal forces during turning. In a 7,5 m diameter tunnel those forces could be super high and that seems dangerous… I hope you’ve calculated these forces and determined that they’re not an issue

  • @todayonthebench
    @todayonthebench 7 місяців тому +3

    I can't help but wonder why it has to run aerodynamically on a flat surface. That seems pointless when the main challenge here is running on a curved surface of a known diameter.
    Now yes, curving the car to the tunnel has its own challenges associated to running on level ground, since the underside of the car could end up bellow the wheels. But one could overcomplicate the car and have its ride height be adjustable. Or make a curved approach ramp.
    Also, will quickly add in that allowing the rear wheels to also turn in the same direction as the front wheels will make the car strafe up the side of the tunnel instead of turning up the side of the tunnel. Effectively eliminating all the issues discussed at 9:10 Though creating a new issue in that the car has to be aligned on axis with the tunnel, so logically the back wheels shouldn't perfectly match the angle of the front ones, having them do slightly less turning will still allow the car to turn, but its turning radius will be massive. Experimentation will determine how much strafe/turning is ideal.
    Adjustable ride height isn't too complicated, but another point of failure. (Even if a compressed air system would be somewhat simple to implement, and I would be surprised it isn't suitably reliable. The system is "fail safe" in that if the lift cylinder doesn't decompress, then one won't attempt the inversion since the ride height is too high for proper aerodynamics. And if one can't reapply pressure after the inversion is done, then one will simply skid when going back out onto level ground.)
    But a curved approach/break segment before and after the tunnel is likewise trivial, especially at these somewhat low speeds since a long distance won't be required. And these segments are likely going to be quite cheap. (I suspect it to be more expensive than a piece of plywood and some 2x4's.)
    In the end.
    You want to drive a car inverted on a ceiling, you have to think outside the box. Your road is a more or less perfectly straight tube. You don't need to turn and you don't need a car able to run on a flat road.

    The curved tunnel seams to be adding many complexities to a fairly simple idea. Would it not make sense to investigate the idea of a straight section of road surface that could rotate through 180 degrees. This could be fairly low in overall height (enough to accommodate the vehicle height and also some additional safety features, like free running wheels in the event of loss of downforce)...?

      It would need to be a really long section you’re trying to rotate. The car is moving at about 80mph and it’s going to take at least a few seconds to rotate something that large. You’d be looking at probably rotating a mile long section of track.

    Do you have to transition into being inverted? What if there was a way to have the car start attached to the ceiling, and determine what length of secured inverted rail/track you need to build critical speed. Build in a safety margin and then have that inversion safety track end once sufficient downforce is generated. You would still have to transition out of inverted, but if the track also turned in the transition area (think like a NASCAR oval, but a wider radius) you could also maintain centrifugal force in the transitionary phase to the ground

    This project is mental and I think deserve lots of safety protections.
    There is an old MS-DOS game called Stunts where you could do amazing things like loops, jump over massive bridges and .... drive upside down in a cylinder. Well there is obviously some limitations in the physics of the game at some extent but what I learned from it and from my engineering studies is that it's very tricky, though possible. One thing to note is that at least 2G is needed because 1G (normal) - 1G (upside down) = 0G (considering 1G as the force that equals the mass of the car) and this means you are floating in the surface. If you manage to put 1 extra G you will have, well, 1 net G and with 1G you might expect a behavior of a car without aerodynamics in the normal world. In other words what I'm trying to say is that the car you always behave as if it have -1G, simply put a car that can produce 4G in normal circumstances will deliver 3G upside down, so one might expect 3G behavior. On top of that the transition in the cylinder is very trick because you need to turn the car to keep momentum in the normal to upside down phase and deal with the loss in Gs and once you are getting upside down you need to straight it back, but with less Gs ...
    It's dangerous, very dangerous.
    And I'm really thrilled by the idea.

    Way way back in about 1975, the company I worked at used the MIRA wind tunnel. Back then, and possible still does, the wind tunnel used four Lancaster bomber propellers powered by BIG electric motors, so we always did the night shift when the power was cheaper. Being the lad I had the job of going out to get our meal, which meant driving all the way to Coventry for the nearest Indian Restaurant - I bet there are hundreds nearer to MIRA now. When I got back with the meal I decided no one would know if I did a quick lap of the banked circuit, so I found my way on to it in the pitch black, driving a MK4 Zodiac with soggy suspension. Well when I hit the first bit of banking, it scared the life out of me. The transition was much faster than I expected, and with Armco on the outside, driving that pig of a car, it was not as much fun as I expected. The car is forced down on its suspension and you can't see more than a few yards in front of you. As it happens, there was MUCH worse to come, because after driving through the second banked bend I thought I knew what I was doing, and floored it. What I didn't know is that there are three banked bends on thee MIRA high speed track, and when I hit it I found a tarmac laying machine blocking the middle lane. Thankfully the outside lane was clear and I managed to swerve through the gap, but that was the nearest I have come to dying in my 74 years. I never did tell the guys when I got their meal to them.
