Late comment: try to put dimples on the bucket's surface, it will provide more "air traction" by creating a microlayer of turbulence, sucking the air to the bucket surface, improving Magnus' force. IIRC, at a certain rotational speed, MF will actually be getting efficient and after that, it'll just basically stall.
It always amuses me how humans finally managed to build a heavier than air craft in the early 1900s, and now they can make anything fly.
Because science . :)
@David Hernandez No, the power density of motors was more important. Once the motors reached that threshold, flight was figured out within a few years. There were decently effective manned gliders in the early 1800's.

Im pretty sure you can make a literal block of steel fly in you strap it to a mig 17 engine
Heavier than air craft have existed since antiquity. Reasonably safe manned aircraft were invented in the 1900s.

His plane cant fly bc of the back wings that can't hold that balance of it and it bends
Haha,good one!
Really admirable level of determination.
The Flettner wing is interesting because the (Kutta-Joukouski) calculation to solve for flow around an airfoil by conformal transformation begins with the solution for flow about a cylinder with rotation. Great experiment!

For those who are curious as to why spinning cylinder wings dont work in practice (and therefore are not used in modern aircraft design) spinning cylinders produce too much drag. The reason it creates so much drag is because the extreme curvature causes flow separation (which can cause stall).
Now despite it not being all that useful for aircraft, it can be used in sea ships for propulsion (look up flettner rotor ships). This can also be used when playing sports, as one can put some spin into a ball and therefore control the trajectory slightly by generating lift one side of the ball.
I admire your will to fix this thing over and over until it flies
KFC should offer you an advertisment contract.
Red Bull is not longer the only thing that gives you wings. As long as you can rotate them fast enough XD
I wonder if it would be more stable with greater wing area-like add two more buckets by gluing tops together.
I wonder if you can use Red Bull cans to fly
Chickens always had wings.
@@timothyhays1817 yes, but they dont fly they do little leaps.

The magnus effect is at VERY slow drum rotation speeds. You need to show those buckets down _a lot_ and maybe consider much longer cylinders, travelling at maybe 50 rpm. The magnus effect would be diminished at high rotational speeds.
I hate to break it to you, but I don’t think Peter wants to even think about the Magnus effect anymore.
peter- it seems that a magnus effect plane is inefficient but i heard a magnus effect sail boat is actually very efficient and cool could you build that?
that would be cool
I am a professional racing sailor.....I'd love to see this. Let me know if you need any help Peter.
ya
Fuck yes sailing with kfc bucketship
I'd love to see that your the boat man as well. make it a super easy no 3d printer hull. like plastic trays or bottles or something
Imagine what it would be like to fly a lifesize version of this thing... I can only imagine the terrified faces and shrieks of passengers witnessing the Colonel's fine likeness rotating madly around a large axis...
hahahahha, I laughed while reading and picturing that! :D
you have forward pitch torque from the rotating buckets. might do to move them back a bit so the front weight does a better job of countering that.
might also be good to have a larger area rear tail wing to maybe get better pitch stability.
you definitely will only get magnus/bernoulli lift if you're moving forward relative to the rear-ward motion of the top side of the buckets.
super fun idea dude!
What would be really neat is to have a drive shaft for each bucket, and a flight computer that alters the speeds on either side to balance the rolling moments.
Still better service than United Airlines

Pretty sick, I think two motors with independent throttles and you could eventually learn to make small adjustments or a tail that can steer like airplane wings, tail might need to be wider for the latter
Your perseverance is amazing!
Should have used buckets full of wings.
I see what you did there.

you're all wrong, empty rail/flat top upper like The Walking Dead, everyone knows the most accurate setup involves no sights whatsoever! :D
Peter, or, or, iron sights with optics, just so, that you can't remove the covers. Everyone knows those are the right choice.
Although i absolutely love the kFC buckets i think that Home Depot and lowes sell similar paper buckets for paint those might be made to better specifications that eliminate the wobble / balance you are getting out of the chicken buckets especially that you know it works and is stable to fly basically
Great videi! Loved it all. I believe the buckets were generating way too much wing lift, more than the prop and control surfaces could counteract to maintain horizontal attitude. Smaller diameter, or slower, buckets and/or larger control surfaces might allow the required forward motion. The whole Magnus things is so counterintuitive, especially the open Fanwing design. Oy!
Spot on and right. Buckets were way to large or the fuselage and rear horizontal/vertical stabilizers needed to be much bigger. I would like to see him build one that is built to functional specs.
That's on my Bucket list.

Now your just giving them to much credit their aircraft have probable evolved into toothpicks
Well done! Instead of spoons that will introduce more drag and instability than lift, perhaps consider gluing several equally spaced longitudinal shallow static wing blades, glued to the cups to grab and push air. The depth and spacing matter, and the blades should be wing-like where they maximize drag/lift in one direction but minimize in the other as the cups rotate. This design allows more maneuverability due to its instability, but isn't fail safe because there is no glide on engine/motor failure.
You guys are amazing. I was adamant the bucket plane would never fly. You proved me wrong.

Yeah that's an awesome idea man! But then to turn it up to 11 put golf ball dimples on it. Lol
AES 2015 hahaha
I think it works because the bucket pushes the air over the top faster and the air on the bottom slower, which is doing the same job as an aerofoil by making it denser on the bottom than on the top.
Awesome idea, however one thing I noticed is that in aerodynamics you want the air on the top of the wing to be faster so that the pressure underneath provides the lift. I would try rotating in the opposite direction, plus I would build a larger tail so that the air movement across the tail helps counteract the body rotation when the buckets start to spin.

Nope lol

next step: differential lift by having the buckets spin independently :)
**head explodes**
that would have solved my roll issue!
haha, I got the idea ... from your differential steering ... the human brain is incredible. We make or miss connections really randomly.
nraynaud1 that is step 2. step 3, tilt motors so bucket axis can form a dihedral to increase stability, have thought about that detail?
also a canard configuration would prevent stall / over pitching.
Practically, you may be on the way to makeing a new type of VTOL. If a person could make a housing for the drums. But, the more moving parts, the more maintenance.
Very interesting video. Thanks!
Nice and useful experiment, although the solution with the crucibles was more about the Coanda effect and the plane was kept in the air thanks to the powerful propeller engine. The Magnus effect is good for ships, not aircraft. It is a pity that you did not use the forgotten principle of a freely rotating wing in the longitudinal axis in the shape of an "S" profile, which does not require a drive like crucibles - they rotate by the onslaught of air. In the last century, we have used it as tethered dragons that have created great buoyancy.
That was pretty cool. You would have gotten better flight with straight tubes instead of cone shaped buckets. Still, I'm super impressed that you kept At it till it worked. Nice job.
The propeller is nullifying the buckets Bernoulli effect.. place the propeller above the buckets.
Iron Bear too much spiraling slipstream, you’re probably right
It will be a helicopter then
What about a pusher propeller instead of a pulling one?
Yep true

Its the chicken effect.- cause of the chicken wings were in buckets. Flies about as well as a chicken
Well none of our chickens have ever done a power loop.
You're thinking of penguin,chickens fly.
Lay Dillie Barely. Chickens can only get a few feet in the air.
You are so smart! I knew a thing that the chicken can fly!
Chikens dont fly
I would recommend increasing the length of the fuselage or increase the size of the horizontal stabilizer. Since added fuselage length would not add significantly to drag that would be best. The problem you were experiencing when you increased the RPM of the buckets was the additional torque this caused overpowered the horizontal stabilizer causing unwanted pitch of the aircraft. I.E. You wanted to increase the lift from the buckets, but got unwanted nose up pitch as well. The amount of unwanted pitch exceeded the amount of elevator control you had. To counter the unwanted pitch, increase the lever arm of the horizontal stabilizer by adding length to the fuselage. Great video, keep up the great work!
Or maybe weight management? The center of mass probably too far behind and the increase in lift from the buckets made it more easier to just make the plane flip backwards. There are no counter measures against that and it would probably just strain the elevators.
Ok me smartie pants
Just one word
COUNTER ROTATING CHICKEN BUCKETS.
OKAY 4 words
Did you consider a rear-mounted, counter-rotating pusher prop? It seems like the thrust from the propellers would really mess with the already weak lift created by the Magnus Effect. It would also lend to correcting the nose-heaviness of the craft.
I’ve never been more thrilled to see one of your projects fly 🤌🏼🤌🏼what an amazing device 😊

Put a motor on a chicken and see if you can get it to fly.

Great job and enjoy how you accept your failures as much as your successes.

Actually, some early planes used this. Even ships used cylinders as a replacement for sails.
@@dogipug5646 that's rlly cool
@@dogipug5646 They tried everything. I've seen the cylinders for sails idea too. Keep in mind, the "autogyro" was big in the 1920s/30s, it's basically a plane with a passive, not powered, set of helicopter type blades that would rotate once the plane got moving. This allowed having stubby wings and short landings (not sure about takeoffs).
But if the engine stalled the plane would just fall but with wings the plane can glide.
I respect the grind. It was more how much will it take to make KFC buckets fly lol. Trail and error is the best teacher sometimes.

"No props for that!"
"I'm just winging it."
awww, You've GOT to "give him props". bwaaahahahaa
'charged with battery'
I'm curious to know if you attempted to fly it without the buckets spinning at all. There were more than enough moments where it wasn't flying so much as "hanging" from the propeller.
Seeing kfc buckets spinning that rapidly is the funniest thing I've seen all day.
This has probably already been said, but if the props were level with the top of the buckets the magnus effect would be much cleaner. As it is the prop wash will be messing up the downdraft.
What if the props were behind the buckets? That way the thrust would not interfere with the airflow at all? If you put small control surfaces behind the props you could also potentially control pitch and roll more effectively?
The Original Boom good idea but it might mess up the airflow behind the buckets and also make it more unstable, but then again what do I know
Airflow and buckets is an oxymoron. Buckets aren't meant for such an aircraft. Too much drag. Maybe a helicopter type design?
When you introduce a backwards spinning cylinder to airflow, you accelerate the air above the cylinder and decelerate the air below the cylinder. Fast moving air has less pressure than slow moving air, so a pressure differential, and thus a lift force, is generated. This is the basis of the Magnus Effect. A conventional cambered wing works in the exact same fashion: fast air on top, slow air on bottom. This is why the cylinders must spin with the top spinning with the wind.
A major flaw in your design is the two props located below the buckets. The propwash accelerates air right past the bottom of the bucket, essentially negating the velocity gradient you create by spinning the buckets in the first place. You should try either mounting the props above the cylinders, to further increase lift, or even a pusher configuration to eliminate the propwash problem entirely!
Michael Perrino And in his "flying" portions the plane was at a huge angle making me wonder if it's not just flying off the props and tail force
What he said
So if the buckets were bigger and rotate faster, would it fly better? Would it help if the buckets had some sort of grooves?
I think in general, faster would be better. In essence you want to look at the Kutta-Joukowski Theorem, which states that lift force is equal to (density of the fluid)*(velocity of the flow)*(circulation if the air). Circulation is harder to define, but in essence, the higher the velocity of the rotation, the more circulation. However, the circulation is also dependent on the radius of the cylinders, and a fixed torque motor spins a larger diameter cylinder slower. So you'd have to find the optimal size-rotation velocity ratio. As for the grooves: you'd need to optimize that as well. Too many deep grooves would cause too much drag, but if the cylinders are too smooth, you couldn't have the friction to get the air circulating fast enough. It's a hard to define problem and depends in a lot of variables. Trial and error is probably best in the scope of this video.
i cant think of the name of the effect, but i think some of the instability may have also been caused by the rotation itself. when you have something untethered and spinning in a vacuum, or in this case suspended in air, spinning objects have a tendency to either go straight (gyroscope effect) or flip 180 degrees but keep going straight also( cant think of effect but there is videos from the space station with tops that keep flipping direction. in order to turn this, he has to fight the gyroscopic force that induces rotation up and down when he tries to turn
This looks like old paddlewheel boat ( and flies like one too it seems) So cool.
I love this black coffe electroswing :D
