[@pauljs75]

Nicholas Rehm made a similar craft. "Spinning Drone Paradox" covers the functionality of the concept. It traded some efficiency in rotor-craft hovering mode to have the ability to use the blades as a tri-wing for fixed wing flight. The big airfoils are symmetric and change pitch at the hub, which allows the RC craft to both hover slowly and fly in a straight line somewhat quickly. Kind of an interesting project, since it's very closely related in concept to the RC craft of this video but also takes on another way of flying as well.

[@goliyth5134]

As much as this intrigues me so, one primary question keeps screaming in my head. All of these wonderful tests are being done at what elevation?

It certainly has an Alexander Calder quality about it, like one of his mobiles. I can’t help feeling that the landing gear needs to be formed like the canopy arms of an umbrella with balls stuck on their ends.

[@rubitracks]

Instead of control surfaces, would it be of benefit to use the servos to twist the wings?

[@lohikarhu734]

I saw an interesting application that used a kind of spring system on the rotors, and changed pitch by doing rapid changes on the servomotor drive, using the inertia of the blade, and the sudden acceleration/deceleration of the motor to torque the system into desired pitch, at a particular location in the rotation, so it didn't need any funny mechanics on the rotor, and did not need any slip rings to drive motors on the blades, for instance... I'm tired, and a bit sick, so maybe not making much sense... one motor per blade, but coaxial, so that the motors are fixed, and they can change the blade lead/lag and pitch .... sigh... burned out, I am ...

Can wingtip motor's RPM be modulated fast enough to provide (a little) lateral thrust -- spin faster in one quadrant and slower in the opposite? Not that this in any way solves the asymmetry problem. But, if even somewhat effective for translation, a downward cant/tilt to the tip motors might lower the leading blade by brute force.

Early gyrocopters solved a similiar pitching issue by allowing the blades to flap up and down as they each transition from advancing to retreating during fwd motion. However, with your design, this would create other problems. Alternatively, you might try a means of dumping lift on advancing blades.

[@johncongo5856]

What are the cavitation effects on the blades?

[@GruvyTubie]

Interesting, I can see the ailerons are modulating UP on on the direction you want to deflect toward and DOWN deflection to move away from, (I hope I got that right). Nicely done, although they are a bit choppy, jerky . The third 'wing' presents an interesting problem because it must be neutral, so control as it rotates goes UP-NEUTRAL-DOWN and the timing is not proportional, in other words I don't think the ailerons can each divide their UP NEUTRAL DOWN by 120 degrees. It seems to me it is more like 1 rotation in the direction of travel would be more like UP 30 for degrees, NEUTRAL for 150 degrees and DOWN for 30 degrees of rotation with respect to the direction of travel. They appear to just go up and down no neutral? Just a quick guess. How these ailerons move does not seem to have any affect on hover, I think you have mastered that. In addition, you need some threads or strings to show what is happening to the air flow over the aileron area of the wing, it seems to be lacking, therefore the larger ailerons were more stable but still not enough air deflection, perhaps. Also at such low speeds it will need a lot of deflection to have any authority. Just a guess, Jim

[@GodmanchesterGoblin]

I think your up-down-neutral analysis is not quite correct, although the jerky motion of the ailerons from the camera does make it look a bit like that. Each aileron is controlled according to its position around the circle as it rotates. Three are very stable, but you could have 2, 4, 5 or even 6 wings and ailerons. Each is controlled based on how the desired lift vector needs to be applied, based on it's location around the circle. I suspect there needs to be some compensation for the delay cause by the servo motor and gearbox which will take time to change position. In that time the wing has rotated further, and so the servo has to move even further, which means that it tends to be moving from one extreme to the other. Some forward compensation in the software based on the rotational speed may help with this and make the aileron operation much smoother.

[@myotherusername9224]

"you need some threads or strings to show what is happening to the air flow" that;'s called 'tuft testing' and yuo're right he needs it.

[@bcstrings1]

Amazing man so smart love the vids keep it up!!!!!

[@mkrepps]

I really like the shots where you attached the camera to the root of the airfoil so we could watch the control surface movements throughout the cycle of rotation, but my favorite part was the slow-motion video at the end. You can really study what's happening and even see the flight control inputs are required 90 degrees prior to the motion desired (due to gyroscopic precession). Keep up the great research. I can't wait to see the next iteration! I suggest adjusting the chord to be shorter near the wingtips to reduce the induced drag near the outboard end of the wings. I think this would reduce the power required from the propellers to acquire the same rotational speeds with even longer wings which could have a better lift-to-drag ratio (like the wing tips of a glider).

I don't know what it is other than really cool! Looks like mechanical flying art to me. BRAVO!!

@@GoldenCroc Solar planes with crazy flight times whether they are r/c models or full size have been achieved. My question is could you use the light weight 3d printed solar panels developed by the Australian CSiRO as the surface of the rotors in this design to achieve sustained flight in full sun. (Probably somewhere like Australia or Spain that has decent solar intensity). Another idea is a pusher prop placed at the C.O.G. rather than lower down to help lateral speed.

If you werent, thats why I put "If you want rotorcraft, yeah why not" in my last comment as well.

[@patrickfle9172]

With a counterrotating system you might not only equalize lift on both sides, but you could also use the little propellers for propulsion by addin power on those that momentarily point in the direction of travel and reducing power on the opposite side 🤔

[@BrightBlueJim]

Since the rotor is rigid, that is, the angle between the blades is 120 degrees at all times, this would not help. It COULD help if the blades were mounted flexibly to the hub, such that each blade could speed up and slow down cyclically through the course of revolution. That is, the blade flying into the wind could be powered less, so that it falls behind, and the rotor flying away from the wind would be powered more. This could, at least until a certain flight speed, even out the relative air speed on each blade. He alludes to this in the video, saying that the blades don't "flap", or lead and lag (which is what I'm talking about).

[@patrickfle9172]

@@BrightBlueJim that's why I wrote 'counterrotating system' aka coaxial double rotor.

[@BrightBlueJim]

@@patrickfle9172 Yes, the counterrotating rotors would equalize the lift through the whole rotation. I misunderstood what you were suggesting - adding power to the propellers on both sides that are facing closest to forward would indeed give some thrust in the desired direction, and as long as power was increased in a balanced manner between pairs of motors on the two rotors would do this without throwing off the balance of the system as a whole.

[@TheGbab]

I feel that somehow suspending mass and shifting the rotor axis in a thrust direction could help with lateral speed. basically configuring the center mass, batteries etc so that helicopter type flight can be achieved. it has great potential for going straight up. lifting a camera, radio antenna, or spotlight.

Amazing work as always. I've always dreamed of long flying crafts due to the efficiency and weight removal benefits a ''jet' driven rotating wing design gives.

Accordingly, since this is not intended to be a highly maneuverable craft, props with properly sized ducts might also give more lift efficiency.

@@preddy09 not really... I can guarantee that even a typical "traditional" design for this type of aircraft would far exceed even the most optimized coanda-based solution

[@windowsxseven]

@@preddy09 here's one reason - lift is a force perpendicular to the flow direction. Drag is parallel. Having an airfoil below the propeller would just generate sideways force (airfoil's lift) and downward force (airfoil's drag) as the flow streams downwards from the propeller. Aside from that the airfoil will also have a blockage effect on the propeller (interference), reducing its efficiency. It's far better to just optimize the propellers instead of placing additional devices that will block the flow. Even if it did generate upwards force, that force essentially comes at the expense of reducing the propeller's thrust, so at best the net thrust will be the same at the expense of additional weight

It can be used like a Nintendo 64 power glove to control the craft, protect you and others from the coil's energy, and is magnetic to the Area 51 alloy of the handle. The attraction is so strong that the link can not be broken by any force outside the glove, yet so in unison that simply opening your hand frees the connection and lightly lowers you to the Earth's magnetic force. The glove also can be used as a zombie attractant for mass slaughter as Mr. Jackson demonstrated. You'll enjoy the labor of love so much you'll become an amazing dancer while controlling the craft with your glove! Very satisfying work along with excellent pay. You'll be a hero!

What if you try'd making it move by deforming the wings?, (using a helicopter-like swash-plate (maybe) to tension and de-tension the blades, making them almost crawl/paddle along the air,......It's very good at self-stabalising.....forcing a direction seems to destabilise it. Would be beneficial to working with this effect, and you'll find it might even move faster than you thought, with less sway..... Science, is not an exact science. 🦄

Dude, how can I build and program one? This would be excellent for people who want to buy drones on a budget

That’s genuinely beautiful … something about its insect-like armature, its sub-aquatic speed while flying, even while it hovers almost as if still, all make it seem like a Martian stick-insect jellyfish. You should bring that to Burning Man. Or, on a very different note, add some well-placed glow-tape to it, take it to the USA’s South at night, and you could scare the bejeesus out of their drunken meth-addled hillbillies.

U.F.O.s might have excelled in this type of basic propulsion,& invented the Anti Matter/ Anti gravity propulsion system, which is 100% silent, cruise at astonishing 4000 km / hour ,that too without any friction of air with their craft, we have to still invent it, until then just laughs like you😃

When you think of air as a really thin liquid, all this stuff starts to make more sense! Cool Project!!!!!!

[@mkrepps]

You're right! In fact, Featherwing beetles are so small they practically "swim" through the air.

[@browniesr4theweak]

Exactly, Flying drones I think of the same sort of concept, Air is mass which you could push off of 🤏🏽👓😳

So cool, looks like something out of Fallout New Vegas or Wolfenstein!
