If it's not interesting to you then please don't engage. Stalking and insulting has only prolonged the difficulty in explaining the point.

Let's try this , open question
if a Rotor can only make enough thrust to pull 3g when light
and it's 1g coning angle is 3degress
then what coning angle would it have at 3g ??


Answer 9degress

supplimentary question
if the helicopter weighs twice as much and the Rotor is capable of the same thrust then it can only pull 1.5g

What would the coning angle be?
Answer 9degrees

ie same coning angle 'UCA'

-------------------------------------------------------------------------------------------------------------------------------------------------------------

there are accidents where the rotor has hit it's max thrust (regardless of energy). 2Apaches, 1 H269(possible energy issues too), 1 NH90

(we're talking about the rotor capability, not the engine's ability to supply that energy/s)

please don't reply if you just want to say how uninteresting it is to you. Crab your noise has degraded the quality of engagement here.
If 'the expert' says it's not true because the Greek helicopter was 20-30kts and it would have to be Vy or above and it turns out that the speed of the Greek helicopter was in fact about 90kts and the expert was wrong then it is only fair to make that point. eh?
Fact shouldn't be determined by popularity contest.
