Genius in engineering, I’m very impressed!

This looks awesome! Congratulations, and well done!

It's great to see your progress! It looks like you had some amazing sustained flights. Much better than my little glide. 😂 I never realized that the one airfoil acts like a wing during forward flight, but that makes sense now. That and probably the higher airflow for the bottom rotor (the one with lots of helpful virtual camber) gives something like a 36% decrease in power consumption at higher speeds. I'll hopefully get my third attempt at a cycloplane flying in the coming months; It'll be interesting to see if it has the same general flight characteristics as yours (hopefully excluding the exploding rotor). Good luck on future projects, I can't wait to see the cool things that you come up with.

Fascinating concept. Thanks for building it!

Great job comparing their performance! Cycloidal rotor will need a lot of optimization to reach a propeller performance. So for me it looks interesting as a concept, but is far from be worth due its complexity and inherent multiple failure modes.

I definitely agree that it’ll take some more iterating and optimizing. Appreciate your comment!

It's amazing to see a man like you trying to make a revolution! God bless you! I really hope you can make it!

Because of the larger "rotor area/wing area" I feel like these could be more efficient, but because of the mechanical complexity will require more maintenance.

Good job. That's amazing.

Great video! this is an interesting project. I'm now wondering if these rotors could be built in/incorporated into a wing where the rotors "tuck in"/"rotate in" to the wing when/where they would be perpendicular to the direction of travel/where they are creating drag and not lift. I'll add this to the endless list of projects I want to get to.

You genius SOB ! Awsome!

I may be premature and giving a suggestion I flew RC helicopters back in the 70s we didn’t have gyros back then but we did have coged belts or timing belt, I think it will help you greatly. Keep up the good work my friend you have amazing ideas

Reminds of that old black and white vintage video of the cycloroter that flew apart a everyone running away!

Usually one such rotor is divided into two. In order to arrange the blades in a checkerboard pattern. It is very difficult to make a blade that bends at the desired angle. It is difficult to make the blades herringbone. It is difficult to put the blades in a spiral..This is a challenging puzzle.

7:45 lol at the frozen reaction during the rain of parts

Impressive

I saw this rotor design in a old documentary video about helicopter history! If I remembered correctly I think it was from 1930 or something

This seems very similar to the Voith Schneider Propeller. These are used on tug boats and have the amazing ability to maneuver the tug in any direction.

I had many thoughts about the same scheme, but with the rotors placed instead of tail elevator & stabilizer. Some kind of combined pusher & active thrust vectoring.

Cheers!! Bro

hi nicholas, i wrote to jude also, that this drive (like the voith-schneider prop on ships) gives different performance with number of blades, length of blades, length to breadth ratio of the blades. the voith-schneider played a lot in water. i imagine in air have other numbers

Impressive project. What a sad ending

Love the paddle steamer plane :D

2nd attempt to take of is gorgeous...

looks very smouthe and stabel

"I need to take a break from Cyclorotors..." ...since its bad to end up like a homicidal maniac... "...but I learned alot..!" ...about my patience limits 😆 Good show, that spray of parts was truly epic... reminds me when I gave up on RC airplanes.

By not reading other comments, intriguing but rule of engineering thumb more moving parts creates higher risk of failure, this is why the basic fan, propeller is still used today in planes and ships.

I would consider experimenting with different shaped blades, e.g. with more curvature. Maybe inflatable would be good for easy changes making testing a lot faster.

Something new and weird is always good, even if it ends up in bits 😄

This concept works very well under a tugboat in the Voith-Schneider cycloidal drive. That’s because the weight and strength of the components is not a restrictive factor. Your project is wonderfully fascinating, but will always be fragile, I fear. 🤜🤛

Very good engineering.

Great job on the project. In the slow motion shot it appears the right rotor exploded before the plane rolled to the left and caused the left rotor to hit the ground. Can you determine if it was a structural failure or did it hit something? I'm looking forward to your next adventure!

@NicholasRehm

Hmmm very good catch. The right rotor did suffer a little mishap off camera that needed repairs. Poor left rotor was collateral damage it seems

@Nicholas Rehm Try using a notched belt so tension / slippage isn't so much of an issue. Besides the tension could torque the frame causing it to twist as more thrust is being applied.

This was educational, fun and created with care. Definitely worth a sub! So count me in!

This is Steampunk as hell and I'm here for it

A flatter/flat wing with ailerons will give you much better roll control, then you can use rudder for ground steering (without the roll) and banknyank for flight control.

How would that work in a narrower version along the leading edge of the wing

Good luck ✌✌

Would adding or subtracting blades on the rotors help? Adding more blades to be like a turbine engine or blower motor fan in an automobile or taking away and going to three to save on weight?

can you put ducts and cages over the propellors?

will the 3d print parts be releases? I really want to try and make one.

I wonder if you could replace a canard with a cyclorotor and use them as a joint control surface/ lift generator/thrust generator?

Would a canard configuration with the rotors between the wings be better?

Awesome Nick! Where did you get your info to make one? How do you keep them pitching correctly?

Makes me wonder what front wheel drive car engine with a continuous ended crank?

the ends of each cycloblades should be a solid dish, would that not reduce noise but at the cost of weight?

You will find different values of performance to be sure, as you are finding out. 6:50 try serpentine belts , toothed belts will rip apart if they jump the teeth, or over load the shafting, slipping a bit will let you bring it home at least .😊

Hi @nicholas rehm what is the clearance/tolerance given for the miniature bearing to get fitted into the 3d printed cyclorotor arm

@NicholasRehm

2 жыл бұрын

Depends on the part size and printer resolution

When it spins. The flaps, even though position slim, causes wind vortex friction. Perhaps a quarter circle frame beam, could shield the return rotation of the fins from the drag of open exposed atmosphere. This only requires a rotate 1/4th circle frame.

I expect some of the efficiency tapering off is due to the motor running out of steam and torque at the high end

@NicholasRehm

2 жыл бұрын

The gearing ratio definitely has the motor at the right side of the torque/power plot. Probably would benefit from a higher gearing ratio in the next iteration

Ojalá que sí veamos este diseño en un futuro cercano

love the concept! but if I could ask for something: it would be really interesting to compare different numbers of blades on these, specifically three and six would be something i'd wish to see!

The prop makes 3x more noise - but gives 3x more thrust ^^

you could make an amazing oscillating fan with this

Voith Drive, nice

Hey. crazy question. What if you added more fins down the 4 shaft assblies? In other word a bi, tri, or quad plane design. Or...what if you added 6, 8 or more shafts assemblies? In other words, what a turbine is to a propeller, make the eqiuvalency of that to this. Another thing I noticed...what if you made it wider? Instead of having the end be not supported you have a fork design hold the other side with a bearing or another motor. Visualize it like this. The standard x shape of a drone but with the assemly held by the posts in the empty part of the x. Did any of that make any sense to anyone?

I spit my coffee out at the satisfaction attained by pressing in bearings. Is that my dirty mind showing or did I really get the joke that was meant?
