3:22 The spinning was probably in part designed to ensure that the flaps close properly and regularly and are not as prone to failing to external factors
That is true. They are attached to "free spinning bearings" and without the turning motion they could randomly close on either side creating gaps and possibly other problems. Turning ensures they always closes in the same direction.
I was saying that the spinning was causing the flaps to rotate or flap closer to the closing point causing the flaps to go into the correct place. It was a good idea, but horrible execution this car was.
Scrapman, I think the entire purpose of the spinning is not to resemble a helicopter but allow the flaps to consistently close 100%. Otherwise, the flaps will fling to the wrong side. But I think that's not what the creator thought.
The idea is this: the propeller construction goes up, with the flaps 'open' letting air through, when it goes down, he flaps will 'close' adding a lot of resistance, generating some lift. It spins so that the existent drag would encourage the flaps to close faster. Which means that the propeller construction doesnt need to spin fast at all, but he oscillation have to be quite long and very rapid for it to function properly. Theoretically this would work. If you disregarded a lot of things. It was probably a take on an ornithopter Oh! Its a wheeled-air-jellyfish Its like using the reed valve instead of a prop
In theory: It's easier just to use a umbrella and when it moves up the umbrella closes, when it flaps down the umbrella opens But it's not gonna work anyway

This might stray from the purpose of real life recreations, but I'm actually really curious if there's a way to make this thing work. The concept clearly works, which is actually surprising, and I fully believe that you might be able to use the same method of catching air to generate lift in something different. Do you think you could make another try at this, but forget about making it look like the original entirely, using the concept in a different shape to make an unorthodox yet somehow functional flyer?
I agree and the one thing I noticed that hindered its flight is the angling of the entire vehicle. If it stays perfectly upright it can actually either hover or slowly gain altitude.
The problem I noticed is that the lower part of the vechicle is too light. The wing-cone is the heaviest part so when pistons move most of this movement goes into the chassis.
@@mixer0014 Yeah, he tried to fix that with weights, but I think he could've found a better way if he hadn't constricted himself with the shape of the vehicle. He had to, as this was a copy real life creation video, which is great content on its own, but it does make the creation much worse than what it could be if he had free reign over the shape of the craft.
If the cone was angled the other way (up), the shape would actually self-stabilize the vehicle in the upright position. Let me give two examples with vehicles that are tilted to the right and drifting to the right. (On any vehicle where the lift is stronger than the drag, tilting the direction of the lift to the right will naturally accelerate you to the right.) First, imagine the (original) vehicle with the cone angled down. The forwards blades (the right ones) are at a steeper downwards angle (because the vehicle is tilted right), so they catch more of the sideways flow of air and get pushed down harder than the rear wings. That means the vehicle will increase it's tilt and you get into a feedback loop. Now imagine the same rightward tilt and rightward motion, but for a vehicle with a cone tilted upwards. Now, the rear wings will be at a steeper angle and catch more of the sideways air flow, eventually stabilizing you. You may still get into an oscillation if the stabilization comes after too much of a time lag, or you may run into the problem of helicopters with ducted fans, which naturally self stabilize so much that their maximum sideways tilt allows them to reach only walking speed, but at least it has a chance of working.
To be honest, the way to make it work would be to put it in water. This is already pretty much exactly how jellyfish swim. It's obviously capable of producing thrust, the problem being the amount of thrust is less than its weight.
The spinning is for the flaps. When it flaps down the flaps have a chance of going either direction which would couse less lift but If the spinning part is spinning then the flaps can go one direction.
This wonderful creation featured in the opening to my favourite childhood movie: Those Magnificent Men in their Flying Machines. And this reminds me of another failed flying machine which features in that movie: the Passat Ornithopter. Yes, you have built ornithopters before, but the Passat Ornithopter was special. It had four wings and a cigar shaped body and that's it. Steering was done through the second pair of wings and the first pair flapped up and down to provide thrust. The Old Rhinebeck Aerodrome where it is exhibited nowadays calls it "quite possibly the most aerodynamically challenged aircraft in their collection". It's hard to find footage of it (besides watching the movie and the website of said Aerodrome) but I really suggest you check it out. It might be quite the challenge to get it to fly.
It might be interesting to try to make something actually fly with this design. Maybe 4 or 6 of those umbrellas working off cycle of one another. It would be cool to see.
I have a good challenge for you. Try to make a helicopter using vertically aligned rotation. (so the "rotors" are upright like bike wheels). I'd imagine they would look like steamboat paddle wheels, and you could vary the angle of the "paddles" to produce lift in the right direction.
Fascinating! The way that it moves almost reminds me of a jelly fish or squid- which makes me wonder: could something like this work well under water? (With a bit of tweaking of course) Alternatively, what would happen if in place of wings/flaps, you were able to use tendrils instead? Not sure how feasible that would be in game, but it's an interesting idea 🤔
I think the original machine was only a test for the flap assembly, it was probably never meant as a working design, just a test for one part, which failed IRL but worked in this video.
I believe spinning was probably a way to get gyroscopic stability For those don't know what that is, it's how a top or a spinner stays up right when you spin it.
Six minutes of Scrapman roasting some inventor from the past for his naivety. *Brilliant* Also, I noticed that once the "car" part starts to spin at the same speed of the blades it starts to lose altitude. Placing a second spinning servo on the other end of the pistons to counter the torque could give some extra lift and stabilize the car
Well this was a glorious semi success haha! I think this mechanism could be used to recreate the festo ai jellyfish with sails which would be pretty awesome!
5:18 Its prototype testing, Scrapman. Why would they spend time and resources for inventing some air controlls while they were not sure if it can fly? You doing exacly the same in Your videos, first make basic frame and test if it's working as intended, in case of succes you just keep going.
I bet adding a helicopter servo to counteract the rotation would add a ton of lift... wouldn't help the control any though lol Gunna retry my bid for Thomas Moy’s “Aerial Steamer”. Secondarily; Alexandre Goupil’s Sesquiplane Keep up the good work buddy! Love this stuff
@Scrapman, there is an car that can glide called the "air-car" and its a modern car with wings you should try making and maybe make it even fly like adding thrusters onto it! edit: realized aircar can fly
and then they removed the "fan" (propeller? umbrella??) and the hydraulic lowrider was born (also your is almost hypnotizing, looks like a jellyfish swimming)
I think you need a gyroscopic counter torque stabilizer. Something heavy underneath that's spinning opposite, so that you don't turn. That'd let you hover, I think.
Hello! Back with another comment, I would love to see you make another version of this! What I have in mind would essentially be the same vehicle but with something that might make it fly! I think that if you added a second copy of the wing mechanism underneath the pistons spinning in the opposite direction/opening and closing at the opposite time of the top propeller it might actually work, the reason I believe this is because when you initially start the machine it pushes off the ground and that's where the momentum seems to come from, if you have this opposite set of blades it should act as drag to keep the machine in place as it pushes the top set of blades upwards and it would counter the torque keeping the vehicle more stable. Keep making great videos!
Idk if you had seen my comment your Tantrum video, but I did suggest that you build this. Either way, thank you for another entertaining video about how historic machines were terrible XD
Hi Scrapman, there is a really cool application called "cheat engine". With that you can slow down and speed up almost every game. maybe you could experiment with slow motion in scrap mechanic or other games
Hello Scrapman you have been my favourite RU-vidr for 3 years now and you made covid way easier. I hope you have a great day. The new series is great by the way.
My gosh this is funny, I actually was thinking of suggesting this weird Sky Car for you to build, but thought "Eh, it's such a dumb design, ScrapMan couldn't possibly make it work." but here we are lol...
Haha, have any other ideas you wanted to recommend, but thought he might not do? Sounds like you're thinking along the same lines as he is. Nice wakfu picture, too
I love how you went trough on probably the same thinking as the inventor. It is better, it is almost working, only if i add something else it could work :D Next idea: Phillip [Horatio F.] Flying machine 1904, 20 wing multiplane
The blade movements makes me think of a jellyfish. Which does move through the water. So I can see where the theory of this flying comes from. However the problem is that though the blades provide some lift, the piston pushes the vehicle back down with grater force. Thus no flight can be achieved. But the inventor is lucky he did not get off the ground. Because He be in a world of hurt as it spins, topples, and crashes.
I'd love to see you revisit these and see what other people have made. Maybe make these a 2 parter and see what other people come up with? Put the challenge out.
To be clear, this doesn't work on the Two Main "Principals" of Flight and Avionics: • The Bernoulli Explanation (Pressure Differential) - The Air Taking a Longer Path Over a Wing or Blade meets up with the Air taking a much Shorter Path under a wing or blade at roughly the same time, Creating a Pressure Differential, thus making the Plane Rise, Creating Lift. • The Newtonian Explanation (Air Deflection) - The Air caught under the Wing is Deflected Downwards, Creating an upward Force that fights with the force of Gravity until the power of that Force exceeds the Force of Gravity, Creating Lift. (Regardless of whether or not the "Principals" above are actually true, the main consensus to creating lift is there has to be a Wing or Blade to catch Air, and Air has to flow towards it) Here are the Sky Car's Flaws: • Bernoulli - There is nothing on the Blades or their Design creating a Difference in Air Pressure, thus rendering this Contraption Flawed on the Bernoulli Front. • Newtonian - There is no Stern, Rigid Angle of attack for the Blades to Deflect Air Downwards, thus rendering this Contraption Flawed on the Newtonian Front.

There's no particular reason this _couldn't_ have worked. It would just need a longer throw on the vertical and a significantly bigger 'umbrella' thing. The spinning I'm guessing was so the flaps would all close the same direction, but I suspect as it sped up it was also preventing them from opening as fully. See, this thing doesn't take advantage of Bernoulli's Principle. So, just like an airplane with a flat plate for wings, it would need _enormous_ surface area to displace enough air fast enough to work as intended.
great Video ! taking old vehicles and trying to rebuilt them in trailmakers is a great idea ! if you need some suggestions, here are 4 planes i would love to see replicated by you, it would be awesome if you would try them out ! 1.Horten H9 2.Messerschmitt Me 153 Komet 3.Heinkel He 112-V5 4.Dornier Do 335 "Pfeil"
Couldn't you put the pivoting anchor or hinge and had a square tube and put tail find or maybe just turn the wings so they face each other in pairs so it won't spin. Then put a prop in the back... and maybe put a gyro on it. This game needs angled parts that you can put blocks on at say 45 and 22.5 degree angles. A bit more programing power would be nice so one thing triggers another and when mixed with delays and such you could make things like a Walker or ATAT from Star Wars. Maybe even a few sensors, like a crude Lidar, motion, light, contact... Better armor plating would be cool... and maybe make certain building materials tougher than others. A wider variety of weapons... including melee weapons (that do not break so fast).
day 149 or 150 of asking scrapman to start a Survival series amphibious tank/basically any transportation and floating base/barge (or under water.) But you need mods... it's a requirement to breathe underwater, if you want an underwater base/transportation. And yes i am talking about the underwater fan moonbo reviewed that basically makes water spaces air spaces... if that makes any sense.) (and if you wanted to move the barge/boat/floating base you are able to make thrusters/glitches/mods to do it or by lift or actual push
Ah, the 1920s invention "suicide umbrella on a flat platform with wheels" unorthodox name, but perfect description of functionality. Works as intended 10/10 would buy
Well interesting concept... My best guess is that this is Biologically inspired since Birds feathers have a similar effect as those flaps, when moving the wings up the feathers let the air pass through, closing and shoving all the air downwards when flapping the wing. That lowers the energy needed to raise the wings again, not generating lift... The Wings themselves generate lift through forward movement an by pushing air downward... Not by rotating in a circle XD Thank you for your effort at creating it in Trailmakers and giving some entertainment and knowledge to us all ^^ Please keep it up Scrapman
The concept was a good idea at the time and there definetly is lift, just not enough, they'd probably need twice the radius of the umbrella thingy and a lightweight modern engine, well everything would have to be lightweight, probably even the pilot. And I don't think it'd be as violent once in the air, at least until it starts to tip too much... Anyways control could be possible with weight distribution and a counterforce. I'm saying all this, because I think it could work nowadays, but it would be extremely inefficient (I am aware of that, yes)
I'd love to see you to try and make this ridiculous thing viable. Like double up the "rotors" and have them spin opposite directions to counter the torque, add a tail boom with pitch and yaw control. It'd be a complete mess, but should work! Also, I'm reminded how awesome it is that we today can model stuff like this to see if it works or improve it. Like, we have more prototyping power in our recreational games than folks had in (semi-)serious research back then.
