- Yellow disk and lower brown disk rotate eccentrically from only a motion source (pink bevel pinion).
Their eccentric (value and direction) can be adjusted thanks two step motors via pink cranks, blue conrods and violet bar. The latter has spherical joint with the yellow disk, cylindrical joints with two red spheres at its ends. Two green cranks and orange cross create a parallelogram mechanism. The brown disk has two pins that slide in a slot of the orange cross.
Four cyan blades are pivoted on the yellow disk. Each blade has a slot in which a pin on the brown disk slides.
The mechanism ensures when the yellow disk rotates, the blades, direction of which is changed continuously, create the thrust in a determinate direction.
The video shows that changing the eccentric direction means changing motion direction of the ship (green arrow).
Increasing eccentric value means increasing the propeller thrust.

That is a very clear presentation of an otherwise complex and hard to understand mechanism.
Brilliant simulation, elegant demonstration!
Thank you sir for taking the time to make this video, it really helps me understand the mechanics behind the motion! Much appreciated!
Lol.. its like a game of follow the forces!! my god.. the guy who invented this must have had A LOT of time on his hands! Working out the combination of blade angles, torques and lever arm positions required to always translate the rotation into single vector thrust must have taken forever!!!
This is indeed a very good animation to explain a voith schneijder unit i never really understood the mechanism
I've been wanting to make a boat with Voith-Schneider propellers since the first time I saw a description of it!
This mechanism is so much more complex than a regular propeller. Does using this mechanism have any advantage over using a regular propeller?
Armo03 you can steer any direction without a rudder. The blades of the prop are actually the rudder. Can be compared to the articulation of a heli rotor with the pitch angles... But the axis of rotation of the pitch is different. Can be seen on tow boats.

Pretty cool, PoonThang. You're the man!

Same the little child was holding when he kissed the back of the car of the nxt
Sun is in my ears\eyes crash outside argos 😂
Primeiro a apreciar mais uma obra do senhor Thang .
Obrigado .
incredible - thank you!!!
Nguyên lý của Cyclo Rotor phải không chú? Cháu đang có kế hoạch chế thử
Đúng vậy, cyclorotor.
This makes the sphinxs hair on the right back dry due to the wind of the women who have the window slightly open at the stecthford lights
Then the somal 3 women at bus stop used low cloud to cver the white scattered sting 😂by the corner of the flats at swan centre

Sir, can you provide STP file? thank you very much，this is really a good idea，I really want to learn.
Please read the video description.
Links to download the CAD files were added to it recently.
Sir wich software u use to make simulation ?
It's Autodesk Inventor.
Thanks sir
