Coaxial Propeller Drive 

I think that the "Mars Helicopter" uses a similar set up? Liked the clip. My thanks.

شكرا ، لأنك من الذين يحبون تبسيط المعلومة وتقديمها لكل الناس. بالتوفيق دائما أنا من متابعيك وأتمنى لك السعادة والسلام

Amazing 👍👍👌👌

Mechanism and your explaination .. it rocks.👍

Nice presentation 👍

this layout highlights something about contra rotating setups that no-one seems to comprehend. the reaction torque of the rotating input shaft. consider, that yoke holding this assembly has to be attached to something... the plane, the engine... to spin the crankshaft one way against any type of load, means there will be a reaction. if this setup was in a plane, the engine would be at right angles hence it would tend to have a PITCH... or YAW, depending on the engine orientation... in any case, it will be to twist the yoke over around the input(green) shaft, in opposition to any load imposed by the rotating assemblies... the contra rotating prop eliminates the "torque roll" of trying to rotate a single propellor in one direction, it eliminates the "torque roll" of the twisting helix of air induced by a single propellor acting on the plane itself, and it eliminates the gyroscopic precession of the propellor spinning in one direction... but it MAGNIFIES the torque reaction to whatever is producing rotating motion to the input shaft. it now has to fight extra friction, AND rotate two assemblies, or double the mass, double the inertia... double the load...

why power it from the side shaft? couldn't the green gear be an idler with power provided to the blue gear, allowing for a linear installation with the piston/turboshaft powerplant?

Superb 👍🏼

Cracked it!

Nice work..👌👌👌👌👌

Very well explained.👌

Nice! Which software you used for animation?

I love this

I'm a new subscriber to your page and I find your animations really ingenious. However, I'd like to know if it's possible to get the 2D version of this animation or the dimensions so that I can try it out too.

Good intro👏👏👏

Wow it looks superb, which program is used for making that

I must say this channel is so underrated. You deserves more views.

Now add a variable pitch mechanism for each propeller and things get much more complicated.

its better to have 2 idler gears vs just 1

👍👍👍👍

Beautiful dude

but it will have a great friction wont it?

Nice work 👍

Which software your are using

Best animation

why a counter rotating helicopter will fly when the upper blades n lower blades are spinning at the same speeds in different directions?

Good job 👌👍

Amazing.

It's really great video👌

Coaxial Propeller Drive

What's that gear shifting for?

I'd love to find out if such a drive can function like a cars differential. If one gear is slowed or stopped, can the other gear then increase in speed? I'm not particularly proficient with gears. If this doesn't work in that way, do you know of a drive that functions like that for coaxial propellers?

Do you have the link of the project in the simulator to download?

How the coaxial rotor helicopter make a yaw movement, there's must be have a slightly different speed among the rotors??

Awesome

Superb mechanism bro

लेट पण थेट👌👌👌

👍👌

Molto bene dove posso trovare il materiale ne devo o Costruire una

wow interesting

How is yaw controlled? (without grinding the gears)

C est simple mais il fallait y penser

airplane kamov k32 Russian Spin its blades in this way

🥰🥰🥰❤❤

Tres belle video explicative
