How Does This Fly With Only 1 Wing?

Hey all! I really do appreciate everyone watching, thank you! In today's video we're exploring the physics behind the mono-wing. I started by 3D printing wing sections that was glued in order to complete an entire wing. However, it proved to be too heavy. I made a new wing out of depron foam which worked a lot better. The best way to support the channel is to simply watch my video, thanks guys!

[@Project-Air]

Nice one Simon 😊 So cool to see someone else trying these one winged helicopters! I also based by designs on that original Charybdis design and found the extra stabiliser unnecessary. If the wing has a positive angle of attack, it works just like a flying wing (with no tail). I’ve also found other designs work without the counterweight (again, like a flying wing).

[@baths4carsraspberrypicomputer]

wow

[@THE_MUN]

Ello

[@nlagas]

Now let’s try to find a genius who can give basic directional control. Maybe with some gyro magic? Since it’s rotating an upward force might translate into a pitch or yaw if timed properly?

[@arturpekosz]

I have made monocopters with directional control, using a magnetometer (digital compass sensor). A gyro is usually too slow, since most gyros have a maximum measurable angular velocity of 2000 degrees per second, which translates to only 5.6 rotations per second. So unless your monocopter rotates very slowly a gyro can't keep up.

[@feelincrispy7053]

An old Popular mechanics magazine has a design that supposedly works perfectly

[@macswanton9622]

You humor is matchless. I don't really care which project you pick, your sense of comedic rhythm and involvement rivals the all-time greats, like Buster Keaton. I am a fan!

[@juhanaleiwo]

Agreed!

[@Pomaufour]

Those 9:50 minutes until you mentioned the leading edge of the wing was facing the same way as the prop were Excruciating man...I did not see anyone in the comments mentioning it at a glance...I was screaming internally ! And then...FINALLY !

You saved me from 5 minutes of agony

[@CASFcharley]

It was painful to watch!

[@easr01gmail]

I was in the same state as you were... I simply couldn't understand (unless made on purpose) that fatal error. I will post it on the general comments but unless the rotating axis is positioned at the beginning of the wing, it won't fly.

[@DesertVox]

Clearly, engineering is not his forte.

[@GneasYTC]

Yeah, I saw that, but I just assumed that either a) I was wrong, what the hell do I know about making a mono-wing or b) he spotted the error and fixed it before testing. Never occurred to me that the real answer was c) he made a boo-boo! 🤣 Anyway, this was fun!

[@rogeraldrich2533]

when having issues translating, dont be afraid to just say the word or phrase in your native language. Laura Kampf has said "Geil" so often, im sure everyone understands it now

[@Thomahawk1234]

Yeah, just don't say the same word in dutch lol

[@danielfearn6076]

The weight on the stick isn't to offset the centre of gravity, but to provide pitch stability of the wing. Without getting too deep into the dynamics, the weight on a stick increases the moment of inertia along the wing spar axis which, once spinning, creates a stabilising gyroscopic force that prevents the wing from pitching.

[@IsaacKuo]

Yes, and another function is to set the wing's pitch angle (as well as the prop's pitch angle). The weight basically makes the vehicle strongly prefer to align its "plane" perpendicular to the spin axis. At that point, you can set the wing and prop's pitch angle relative to the weight pole.

[@danielfearn6076]

@@IsaacKuo yep good point

[@Pixelarter]

So adding a servo to move the weight stick up and down, could be used to control the wing angle of attack.

[@gutrali]

Why didn't you stick the pole into the ground to run these first tests so that you didn't have to be in the line of fire 😂

[@stevencrow6935]

What’s the fun in that😂?

[@simonallan9941]

Thats when you would be in the line of fire, anywhere but right below the wing.

[@pierrekin]

Engagement ❤

[@malvoliosf]

Your English is fine. When the wing is free to move, the center of gravity is going to be directly below the center of lift; that is just physics. If that orientation of the wing is then such that the thrust vector is not pointing straight down, the wing is going to spiral off at random. The problem is, the center of lift tends to be halfway down the length of the wing, while the center of lift is much closer to the motor, so the wing will yaw (or bank, depending on how you look at it) severely, trying to get the COG directly below the COL. I don’t see how to overcome this.

[@mandrakejake]

His English is better than some of my English friends 😂

[@IsaacKuo]

It's really untrue that the wing will spiral off if the thrust vector is not pointed straight down. In fact, it's impossible for the thrust vector to point straight down due to drag. The wing has no propeller to counteract drag, so its thrust vector will always point "backwards" compared to its motion. The propeller is there to prevent drag from slowing down the spin rate, but it's pointed in the opposite direction so this doesn't "straighten" the thrust vector downward. It does the opposite, making the thrust vector even further away from straight down. Nevertheless, monocopters work and the fact that the thrust vector does not point straight down simply is not a problem. Why not? Because the vehicle is spinning. That means that the thrust vector sweeps out a cone, and the overall effect is an average thrust vector that points straight down.

[@malvoliosf]

@@IsaacKuo "monocopter"? Should be “monopter”, one wing. But drag is resistance to horizontal motion. The monopter is supposed to hover, isn’t it?

[@MadsenWikholm]

You might be able to lower the weight of the counter balance by placing the battery et al on the other side of the rod, where the counter balance goes. Next phase, make it possible to steer. Just add a servo to alter the wing/motor angle... (I have no idea what that would do)😁 Love your projects!

You have the CG in two dimensions, now consider the third Z axis. From the current CG, drop a flexible rod with a small weight, and use the aileron control on the controller with a servo to push that weight in the direction that keeps the wing horizontal, until you want to tweak it to make a change of direction.

[@lizhikai5587]

This thing also has a free flight version. In 1960s, people flew the gas powered free flight helicopter a lot. Also it has a nickname "The Big Knife".

[@ZR-eq2hl]

I'm not a english native but I understand everything u want to say even watching in 2x speed, so I think everyone can do. Keep going, nice video :)

[@j14152]

Interesting. Suggest leaving the launching rod attached to the wing to stabilize the wing in flight, like a pendulum. Then, with a bearing and a gimbal and two servos controlling the angle of the rod, you can vary the angle of the pendulum to change the angle of flight, like a gyrocopter. The left stick on the transmitter would then control it like an airplane, with elevators and ailerons, to control its attitude. Unlike a helicopter, the angular rotation of the wing currently acts like a gyro to stabilize the wing. You would need a fin on the pendulum, to keep it pointed in a forward direction. If you added weight to the wing tip, that would increase the gyroscopic effect. A wing of that size should be able to lift several pounds, depending on the angle of attack and rotor speed. A thicker airfoil will generate more lift for a given rotational speed. The angle of attack of the wing should be varied, greater near the hub, less at the outboard end, like a propeller blade, with a "twist". Your airfoil may be somewhat thin to generate more lift to accommodate extra weight. A gyrocopter can be thought of as a rotating wing with a pendulum suspended below the wing. In this case, the electric motor rotates the wing, not the forward motion of the blades moving through the air at an angle. Might or might not work - you're the developer, not me.

I like the idea. If I had a 3D Printer, I'd consider only printing the wing's ribs and then assemble with a spar and then cover with shrink-wrap film (as many balsa, RC planes are now covered rather than dopped tissue paper). It would be ultra light and may function even better than what you built.

It's also possible to make a single prop "monospinner" drone without the wing. In this case, the prop is angled more upward, and instead of a wing and weight, there's just two weights. I bring up the "monospinner" because it doesn't require fabricating a wing. This may make it easier to get working. It also doesn't require an extreme spin rate before launch. Obviously, a mono-wing's lift depends on spin rate, but a monospinner's lift does not depend on spin much.

[@mikeking5834]

Protip, those holes actually make the wing heavier. Do the one hole for the dowel and then leave the rest as infill. It'll be way lighter. Add more walls for strength if its too weak.

If you put a weight at the bottom of the launch tube it will help you launch it vertically. Cool build!

Now to add servo and Melty Brain control firmware from BattleBots. (Melty Brain is a type of battlebot that spins whole at high RPM using differential speed control of its wheels; the onboard computer determines its momentary facing and can apply small changes of speed to the wheels to make the bot move in given direction. In your case, you'd vary angle of attack.)

[@crawkn]

Virtually none of the lift is being generated by the parts of the wing close to the center of rotation (particularly the part moving backward). Save the weight of that part of the wing, and use the only slightly reduced lift more efficiently.
