One way of avoiding the vertical surface which provides no lift but adds drag would be to switch to a quad-rotor design. If instead of spacing the wings 120º apart, you space them 60º, 120º, 60º, 120º you'd end up with kind of a biplane configuration in forward flight, with all wings providing lift. As a Bonus it would look like a bit like an x-wing :D

[@gadgetmerc]

blah blah blah blah, X-WING!!!!!!!!

[@gillo100]

With the quad rotor style the lift component wouldn't be vertical as would be perpendicular to wing surface, so you are losing a decent amount of lift and as such I'm not sure it would be worthwhile as you will still increase drag. But since you bring up x-wing, why not rotate the wings similar to flat (ftl) and x (combat) mode for the x-wing :D

[@emanueley8410]

@@gillo100 you'd have the lower wings at -30° from horizontal as now, and another pair above at +30° from horizontal

[@Dragonsrage012]

I would think it would require some major fly by wire compute power to controlled flight. With your x and y changing constantly it would be very hard to know what way is up.

[@theapexsurvivor9538]

It'd probably lose all its lift, so probably not very efficient.

​@@Dragonsrage012 he currently has the lidar pointed radially downward between the bottom 2 rotors, but if he had it pointed backward, he could use that to measure altitude when flying at high angles of attack.

[@tylertripp4939]

Something that could help with the drawbacks of symmetric wings could be to add flaps that could be angled down symmetrically during forward flight and with rotationally symmetry during spinning hover. You could also add a tail to help keep the craft parallel to the ground during forward flight. This is a really cool concept

[@Rizzob17]

[@tokumei_llc]

You can counter the spin with a 4th propeller spinning the opposite direction either on top, or under the central body. Also if you modify the 3rd vertical wing, (or all 3, so that 2 are wings, and the third folds back to create a sort of tail) to fold back at the axis pivotal point, when it shifts into its horizontal flight mode, you'll reduce drag even more as the 3rd "wing" could become more of a tail, where the 3rd propeller could function as either a small tail wing, or if turned on, I believe will help to shift the Pitch of the aircraft.

[@amazingdiyprojects]

Spinning VS traditional forward flight efficiency was kind of surprising. (One year later edit....: OK, so now it finally dawned on me. The lower "stay in the air" efficiency is off course just plain old wing loading. When spinning the aircraft its mass is distributed over the combined area of three wings, and while in forward flight only two which forces you to fly the wings at less efficient (higher) angle of attack. Then on top of that add the extra drag you mentioned generated by the passive third wing. However, if efficiency is measured in taking a specific load, mass, from A to B, the "airplane" configuration still might be the most efficient one of this amazing little crafts three modes.) Absolutely amazing work you done here including your video editing/creating skills, thanks for sharing. Crashing is sort of mandatory when embarking this kind of endeavor!

[@NicholasRehm]

Agreed, I was a bit surprised too. Anxiously waiting for your manned version😉 And yes-crashing is the only way to force me to iterate!!

[@amazingdiyprojects]

@@NicholasRehm Silly question perhaps, but have you tried to fly the craft in airplane-mode with the vertical wing turned down instead of pointing up? Generally speaking I think it is much more forgiving and efficient to mess with the airflow on the high pressure side (under the wing) rather on the top side. Im thinking that there is a lot of wetted surface in the middle of the low pressure lift-distribution curve of your wing. Any how, something is off, you should be able to fly it more efficient in airplane mode then you done so far. Looking forward to what ever comes next!

[@dougwilson6828]

I really enjoy this idea. Well done. As a fwi check out Mike Pate's Scrappy real world bush plane build. Specifically his ability to change the wing's profile while in flight to optimize the low speed vs high speed efficiency. kzbin.info/www/bejne/rZ3adaurrcd7qtE Mike's an amazing design/fabricator & engineer.

[@ekinteko]

@@amazingdiyprojects The pressure difference would be non-existential. Whilst drag could be more of a culprit when near floor. But having the tail on the top end, similar to a commercial plane, will pitch the nose up. And that is better than pitching it down. All in all, it shouldn't make much of a difference. If he were to have the plane in forward flight, AND, start spinning now that would be detrimental to the energy used, speed, and the excess drag.

[@ledfootfam99]

4 wings that collapse like an x-wing when starting forward flight. 2 wings could be shorter for the propeller clearance or find another way to offset.

[@hprfire]

what about a 4 wing design that flies forward like an x wing so all surfaces contribute to lift?

[@chir0pter]

Whoa

[@timplett1]

I had the same thought, possibly with 2 pairs spaced closer together, rather than all 4 equally spaced around the perimeter. I'm assuming that having the wings at 45° above or below horizontal would greatly reduce their lift efficiency, leading to no actual gain, but that is purely assumption, I could be completely wrong.

[@hprfire]

@@timplett1 it is all about chasing the trade offs. closer spaced wings would be better for forward flight but might decrease hover efficiencies. never know until you try. Thanks for sharing your research I love this type of stuff.

[@dnomyarnostaw]

I suggested that to him on Discord 3 weeks ago, but got no response.

[@obstacleman]

​@Tim Plett I would think 4 equally spaced for hover stability and then close them together or at least to a 30/70 split for forward flight. It would increase complexity of course

[@stormthrush37]

So this is basically a flying propeller. Pretty cool!

[@darrenconway8117]

Have you considered maintaining the spin in horizontal flight? That would allow asymmetric wings for improved lift in both hover and forward flight.

[@jetstreamer3]

Have you flown it in a "Y" orientation in forward flight? Any major difference from the "λ" orientation? I would imagine it would be more inherently stable.

Without a tail that would create some gnarly pendulum effects. The A orientation is more stable once flight speed is achieved. We dont have to worry about stalling or stability with such good thrust vectoring.

I love this design, but most of all I love that you've taken it so far. Lots of experimental drone concepts don't get beyond the proof of concept or gimmick phase, but this is already so much further along and shockingly usable. Very excited to see where it goes. Also, have you given any thought to potential folding mechanisms for the wings to enable some sort of transition to a bi-wing during forward flight, or some other configuration that would at least allow the top wing to convert to a lifting surface? I can imagine the complexity and weight of mechanisms like that would be too great to be worth it, but I can almost imagine that there might be a sweet spot or very creative way of accomplishing it in a way that's efficient.

The spinning hover could also be good for non-visable optical or radar sensing. Lots of times it's way cheaper to get point and line sensors for odd optical frequencies.

[@GeorgeCowsert]

Here's an idea to test: A quad-blade design, where the top and bottom fins are slightly smaller but still articulated. It should allow for finer control than just two articulated wings with propellers, while still having the stability and efficiency of spinning hover.

[@Space_Trash]

Would it be feasible to make one of the fixed wings actuate and lay back at 90 degrees during forward flight to reduce drag?

[@Jazucu]

I was going to suggest variable pitch on *all* of the wings, but just one would be a great start! Bet it would be an engineering nightmare though.

[@Space_Trash]

@@Jazucu shouldnt be too hard to trigger a linear actuator when transitioning to forward flight, either manually or via accelerometer data.

[@paulscullin7312]

If the vertical wing was hinged at the back/bottom it would it would automatically fold back when the wings motor power is cut. Restart motor to unfold.

[@ellindsey000]

Thirty-ish years ago, when I was in high school, I drew up rough plans for an airplane shaped like this. I never built it, of course, but I was always curious if the idea had any merit. Nice to see someone else had the same idea and the ability to actually build a model to test the concept out.

[@rowlos123]

What happens if you spin the drone in forward flight? Does that just not work? Your solution to being able to control the hover would probably be similar to allowing the whole drone to spin in forward flight. You would have to vary the speed of the props depending on what point in the overall prop rotation they are in...this would be very complicated, but also very cool.

[@grouchyfluff]

In essence, this turns the whole thing into a helicopter rotor of sorts in the forward flight regime, no? I wonder if introducing independent wing-angle control would unlock potential to adjust blade angle, similar to the effect a swashplate has on helicopters. This might require 2 more fairly robust servos and some VERY beefy code, however.

[@JMMC1005]

This seems like it could be quite efficient, as you're now using the efficiency gained by the large 'rotor' to produce your forward thrust. On the other hand, I'm struggling to visualise at what point it stops acting like a high-rpm propeller (i.e, lift is just the vertical component of thrust), vs something like an aircraft doing a slow aileron roll. My gut feeling is that these are fundamentally different flight regimes, with the former scenario not really providing much of a 'wing' effect (i.e. airspeed-dependent lift). But I'm not really able to come up with a good argument as to *why* the situations differ.

[@rowlos123]

@@grouchyfluff yeah I was thinking this, you would need to independantly control both the small props and the wing angle of each. Then you should be able to have some pretty good control of the lift and counteract any rotational forces which would send it off course. You could make the code of the wing angle a little easier by having a mechanical guide which adjusted the pitch of the wing in a certain part of the rotation, the electronics could then adjust this guide which would influence the wing angle when it is at that part of the larger props rotation. To do that, you would need the center of the drone to be on a gyro and level as the reference point. Similar to what WW2 planes did to stop them from shooting their own props but that wasn't adjustable.

[@NicholasRehm]

@@JMMC1005 yea efficiency-wise, rolling in forward flight would be equivalent to doing aileron rolls which are less efficient because some of your energy is diverted to maintaining the constant roll rate as you move forward

[@JMMC1005]

@@NicholasRehm Would it be quite the same, though? In an aeroplane, your wings aren't pitched to match the roll (except for the ailerons changing the effective chord), and your propeller isn't driving the rotation like your tip props are. Would be interesting to see the numbers.

[@papparocket]

Wow, this is an incredible concept and cleverly implemented. I have one suggestion for improving energy efficiency during forward flight that would hopefully have little or no impact on spinning hover efficiency and potentially better non-spinning hover. And that would be a four wing configuration with two long wings and two short wings, each with a thruster. During non-spinning hover, if you use the same propeller and motor combination you will have four rather than three props, and thus have a larger disk area, and thus reduced power for a given total thrust. But this will also potentially make the drone heavier, and so that would require more thrust. So I am not certain that it will reduce total power compared to your current symmetrical three rotor design. Only design will tell. During spinning hover, the long wings will provide most of the lift while the two short wings will add some. If the total area or at least the wing loading stays the same as the three wing design, I would think that power required for spinning hover will be at least very similar. As with non-spinning hover, if the total weight goes up, then power required could go up. The big change should come during forward flight. The two long wings will be horizontal with their lift vector parallel to the gravity vector and so yield a higher L/D for a given wing area and CL than the Y-wing with the lifting wings at 30 degrees to the horizontal. Also the total area of the two short wings could be less than the one large wing wing that is vertical during forward flight in you Y-wing. The length of the two short wings would be determined by the required moment arm required to produce the necessary pitching moment using differential thrust from the two propulsors on the short wings. Differential thrust on the two long wings would provide the necessary yaw control and differential pitching of the two long wings would provide an awesome amount of roll control. Since pitch is not coming from aerodynamic lift, the area of the two short wings is not a factor and so can be very small. In fact in the limit the wing chord could be just long enough to provide a clean aerodynamic shape around the rods providing the structural strength. In this case lift in spinning hover would come almost entirely from the two long wings. As for your potential applications, I like your idea of providing a relay between widely separated locations on the ground. Another could be between a ground controller and another drone that is operating beyond line of sight. One use could be powerline and pipeline inspection where one drone either flies in spinning hover in line of sight to the controller to provide control relay to the second drone with the camera and/or other sensors flying in horizontal mode along the powerline/pipeline.

[@AuthenTech]

incredible video quality, well done man!

[@markfeeer2149]

Maybe a possibility to increase efficiency is to have separately angled wings. So forward flight you can increase / decrease the lift and keep the props more in a level state.

Would a deformable wing that tapers or straightens optimize efficiency?

For forward flight in practice you really want to locate the minimum of energy per distance traveled, not just minimal power (energy per unit of time). It doesn't matter how little power you used if you are still nowhere near the target.

[@contagiousingenuityagency5273]

That's a fantastic project! Here's something I noticed. As is during forward flight your two bottom 'wings' are oriented in a way which creates anhedral. As well, the vertical surface raises the center of gravity higher, thus contributing to lateral imbalance. I'm thinking if you were to program it to fly with that middle wing facing down, the flight controller won't have to fight balance issues because you now have a lower center of gravity and dihedral.

[@crunchybones2528]

what's with the random caps buddy

[@jwg72]

I don't think that the third wing is the reason for lack of forward cruise efficiency... the effect shouldn't be that large... I'd look at the airfoil design... perhaps adjust the angle of attack of the two lifting wings separately? I wonder if the craft could be flown upside down with the non-lifting wing underneath and the motor used to shift the cg relative to the other wings (thus allowing adjusting their angle of attack independently?) That might be a bit complicated though.

[@wearemany73]

…have you considered flying with the wing geometry (post transition) in the dihedral config rather than the anhedral config? …which means you could utilise the inherent stability and achieve yawl control by thrust vectoring L/R and pitch control with the remaining motor. Also the “video capture while in rotating loiter” problem could be solved electronically for live capture and cranking up the ISO and re-framing the video post flight for post-flight capture. 🤔 Edit: Ops! I forgot, great video BTW. I watched the last one and I was immediately impressed by the elegance of the design, well done.

[@TheSe7enman]

Great video! Love that you actually have something useful and quite efficient already in this non-refined stage. In terms of forward-flight efficiency, I think the better measurement would be power per meter flown (or mile). Then you can compare that to the power-per-distance of a regular drone and maybe a bi-wing. It will definitely be in the middle between those two, but I'd love to see how much more efficient it would be than a normal drone. This, I think, is essential to the overall usefulness of this forward-flight mode because as you mentioned, the forward-flight mode would probably be used in a scenario where we want to fly as efficiently (and fast) as possible to a certain location.

It may sound ridiculous, I may be dumb. But like, what if behind that you had a smaller set of 3 spinning blades that were on the same axis as the larger blades. Then you would just place them both on reverse of each other. When In “hover mode” you change the “pitch” of the second set of blades to direct the wind/craft. Then in “fly mode” you have them spin the same axis as the smaller blades to assist speed. I’m not an expert. That would just be my uneducated hypothesis.

It would fly horizontally as a straight main wing in two halves, with a stubby fin up and down in the middle of the craft. I dunno if that makes any sense. I want to see more of your work. I have subscribed.

Very nice design and video!

Пока смотрел - закружилась голова...

Dude this is awesome

[@NicholasRehm]

Thanks!

I think as a rotor system for an Osprey style craft it would be more effective providing greater lift and stability while if one or two of the 6 motors fail you would still be able to make a long controllable autogyro to safety instead of immediately crashing

[@samchandler2527]

I think its much more useful as a controlled in-sight tool than a transportation or quick response vehicle. Distance could be traveled while in rotor mode using less power - it won't be fast but its very useful. Savng battery as you say by getting altitude in rotor and then switching to drone to get the shot. For work, being able to conserve power and stay in the air longer is hugely beneficial. the vanes could be solar panels, what a terrific design.

Just amazing!

[@orshaked8013]

one way to deal with the spining if there an ardupilot code on you can use super simplemode so the sticks commands always from the takeoff point

[@NicholasRehm]

we don't do ardupilot 'round here

[@Feeeeeeenix]

once you tackle horizontal control while hoverspinning you could spin it at an angle to get efficient sideways thrust

[@nelsonjanusson7278]

LOVE THIS it looks so cool!!! very interesting. would be fun to build something like it!!!

[@caysebarry3949]

I have a very similar design that I’ve been theorizing. Seeing this video blew my mind 🤯

[@jek__]

I like this thing a lot, it's cute and seems quite capable and versatile

[@JWQweqOPDH]

Maybe flip it over into a "Y" configuration, make the bottom wing shorter to reduce weight and drag, and widen the angle between the top 2 so they're closer to level in forward flight. Hopefully the angle and blade length changes cancel each other out for stable spinning hover.

I can see this as a four wing design with an x-shape in hover and spinning and a with actuators, a bi wing design in forward flight. This eliminates the drag from third wing and increase lift. It's not as good as a single wing, but I believe it would be far better than a tri wing. You also get an extra motor
