Re: [ST] Emile - Coaxial Rotors

[BrettWilson21@xxxxxxx]

Emile,

Thanks for the post with the links to the coaxial rotor system.

Being a pilot, you may be able to answer some questions for me about this.

How does it change direction with only one control movement?

What happens to the coriolis effect from two rotors spinning in opposite 
directions so close to each other?

>From the picture, it looks like the traditional collective & cyclic have been 
done away with, so what is there to control the pitch of both rotors and rpm?

Do both discs tilt to change direction?

In traditional helicopter design there is a 'do not exceed speed' as the 
retreating blade can stall as the forward speed matches the retreating blade 
speed. How has this been overcome, or is it no longer relevent due to the nature of 
two opposing spinning blades?

Please keep your answers short, concise and easy to understand ;-))

Brett.
