I and SO SICK OF THE JIVEASS BOMBASTIC ACTION MOVIE MUSIC!! Why won't you let us hear the "music of the rotor" instead? Are you trying to cover something up??? Because that is literally exactly what is sounds like. Eff that!
With these rotors applied to a craft, do they need to exposed to open air (As in do they need to remain uncovered) or could they be covered over and still provide the life needed to fly?
afaik from what ive seen from cycloidal rotors in like diy drones etc, they do need to be exposed.
Maintenance costs per flight hour?
Lots-O- moving parts. 😮
I see a safety advantage over a prop but great losses everywhere else.
Where do you see great losses? The lack of tip vortices is an improvement over traditional propellers in terms of both drag and noise.
@@brycejensen5201 ...and the relatively lower speed is quieter. No super sonic propeller tips.
@@joergmeyer4145 fuel efficiency perhaps? and increase in weight, so it would need lighter and stronger material which means more cost.
@Stan Cooper this is my problem with it aswel.
and a prop is already too iffy for every day use in this way.
i don't really trust it yet.
@@krain.8245 Fair points, I haven't seen any calculations yet, but it seems to have potential for high efficiency. The airfoils are able to achieve a higher angle of attack without stalling, and as I mentioned before, there is nowhere to generate tip vortices which induce a lot of drag. Ease of manufacture needs to be taken into account though as well. Current propellers are very complex compared to a straight symmetrical airfoil (or several).

Does anyone have an actual flow model of what the air profile actually looks like when the angle of the blade changes? Also is the angle continously changing as it rotates or is it constant? How does the system stay balanced while the blades position move?
I assume balance is same as quadcopters, diagonal reversal of lift to keep it stable. if you're really interested knowing more, why don't you get 3D printer and make a small scale model, but quadcopter and then try replacing quadcopter blades with the ones you print. it should work fine with slight modifications and then you can use smoke to trace the air flow.
@@SethiozProject "if you want to know more, simply reverse engineer this and build a functioning prototype, then test it in a wind tunnel. its that simple"
The angle is continuously changing. For a certain flight condition, the angle setting on their servo will be constant, but if you look at a single blade as it travels around the azimuth, its angle will vary in order to produce net thrust in a given direction. Here's a video that explains it pretty well: czcams.com/video/JoVmejDsMrM/video.html
Nice tech!
Expensive and heavy blades and pitch system just for.....saving rotor clearance area?
Great 👍
I saw a man take off with the help of two blowers. it seems to me it was much more efficient to install 4 powerful blowers and control the flows)
well I've seen people put propllers on a bathtab too and take off with it, that doesn't make it effective and stable. There's a reason why most effective way to fly are planes and helicopters. VTOL is slowing becoming more effective, with this design you can control if you provide lift or forward / backward thrust. so it's basically mix between plane and helicopter, just needs wings so it can glide better.
@@SethiozProject
it could also fly upside down.
or straight up alaigned with a wall
and even hover that way
sadly no strafing or rotating along a single axis to face backwards while hovering in place.
you can only rotate like that forward and backwards so you'd end up upside down if you want the nose pointing in the other direction.
it can litterally only turn that way by banking and pulling up, like a plane.
i guess it could do that in place as well. but it would still need to tilt over and then "pull up" to turn around.
and i have no idea how it would avoid drifting in that situation
I dont know but I think ur onto something. I saw a guy take off in a cardboard box one time. Maybe we should look into cardboard planes as well. Like a cardboard-leaf-blower plane? thoughts?
This is the one
china will have this
Cool! What do the two gears with red belts do? 🤔
Edit: What I mean is, is this the planar motion control to position the pivot center of the blades?
Yes, I believe it is. You can see the blades moving when the gears do.
i'm assuming it's moving around a disk that controls the angle of the blades.
(like a swash plate in a helicopter)
so that they are in line with the direction of movement on one end of the drum. and opposed to the direction of movement on the other.
Typically in a cyclo-rotor an offset crank is used to control the blade angles and the rotation of this controls the direction - Very much like a swashplate as mentioned above by darkracer125. This implementation appears to take things a step further by implementing what looks like differential control. You'll notice that in this video both belts move in the same direction and this looks to control the direction as you'd typically see, however I'd bet that by rotating these in opposite directions the amount of offset is adjusted which controls the amount of thrust rather than just the direction. I can't work out what the mechanical mechanism would be to implement such control though.
@@yngndrw. Ok that's what I was wondering, are they actually moving the pivot AND adjusting the offset? I also can't think of what mechanism they would be using to do this. It's interesting because it's all happening axially through the rotating axis! Very cool.
@@gerrybeylerian5290 action of an eccentric to control pitch is shown in this CycloTech video

but I haven't found an explanation of how the two belt-driven sprockets move the eccentric.
Can we make this rotor design an attachment to a car wheel that has the blades in the proper orientation to produce down force?
My first thought was --- Back 2 the Future DeLorean! Imagine a car that has 4 of those wheels and openable flaps on top of hood and trunk area for air flow, so it can take off just like the car in movie. But downforce also crossed my mind, imagine such wheels on Formula 1 cars! .. well never going to happen, because they are already worried that F1 cars are too fast and reducing their grip. They no longer allow slick tyres either. they further reduced the grip by limiting wings they can put on cars and also Ferrari had some interactive bottom, that changed its shape and gave more downforce, but that was also banned due the increasing grip issues, they don't want to see too much grip in F1 as it gets dangerous, however I'd like to see a car like that. Because the best part about this design, is that you have no stress on suspension, the wheel itself grips to the ground.
this design can further improved on car by making the blade part rotate seprate from tyres, which means it can provide crazy grip / downforce even at very slow speeds. Could be useful on street cars. imagine driving on black ice or wet surface, how many crashes there have been on highways or even surface streets, because someone goes over wet surface or black ice and loses control? Those bladed wheels could easily save you from serious crash.
@@SethiozProject yes! F1 might say no but what about those dudes out at the salt flats trying to set top speed records. Regardless, a good idea finds funding. Love this project and looking forward to see what comes next.
Unless I've missed my guess, this cannot possibly scale to safely and reliably lift a multi-passenger aircraft more efficiently than current designs and propulsion methods.
This was also my thought... it seems to be mechanically very complicated. What are the benefits to simple propellers on a movable arm? I really would like to know the effciency of this special rotors.
Rotor aircraft are not actually all that safe. Fixed-wing aircraft are.
I was actually wondering if this solves the downdraft issues of rotor aircraft that has led to a lot of helicopter crashes. When a helicopter hovers in one spot for too long the wind currents begin to sweep up, over, and then push down on top of the rotors causing the it to lose power.
@@kyle2034 Is there a name for this phenomenon? Or a link to authority?
@@adamchurvis1 called vortex ring state, I learned about it in flight school, but I’m fixed wing so not an expert. en.m.wikipedia.org/wiki/Vortex_ring_state
Don't like the idea of belts spinning the wheel. What if one snaps.
look closer.
360 degree PLANAR control
this thing cannot output to the left and right
🛑, VERY INTERESTING, HOWEVER, I HAVE A DIFFERENT IDEA THAT CAN REVOLUTIONARY WORLD AVIATION, HOWEVER, I DON'T HAVE RESOURCES TO TAKE OFF THE ROLE... A TYPE OF VTOL PROPULSION
Too many moving parts, constant breakdowns
This music is annoying.. I just want to hear what this thing actually sounds like but every effing video of it has this transformers/matrix battle music...
