Counter Rotating aircraft/ship propellers.
If both propellers are on the same one shaft, how are they spinning in opposite directions at the same time?
Whats the configuration of contra rotating propellers?
How did engineers do that?
And whats the purpose of contra rotating propeller?
That propeller configuration fks my brain so much.

imagine you have a straw and you put a smaller stick inside of it, they can rotate independently.
The reason for the counter-rotation is more complicated, but basically when you have something spinning it wants to also spin the thing it’s attached to, having two propellers going different directions cancels this out.
