AnFi - this soft clmax is where I start to get confused, if the reality is that the retreating blades stall, causing pitch up and roll then how can you have a coning angle that is significant in any way.

Whether the coning is caused by too much collective - ie overpitching - or too much load factor - from flaring with the cyclic it will surely always be the retreating side that stalls first, followed by a flap down, maybe some dynamic stalling and unstalling.

Just how is the coning angle in this case relevant or a limiting factor?

Confused.com.

I believe this Ct/sigma also has to do with rotor solidity (which I think means the number of blades) does that factor into your equations somewhere?

many thanks
