Sorry "what is a soft arrival at CLmax supposed to mean versus a dirty and stressful one???" what happens when you pull hard is that you hit a Ct that no longer increases, when you pull harder you get 'stuck' at about the same Ct, the whole disk doesn't stall in the sense that it actually stalls , nore like part of it does and locally Cl reduces but other regions have capacity to increase still. So the effect is a 'soft stall' compared to an aeroplane where they also try to make stall 'soft' by arranging higher angle of incidence on the inborb part of the wing.
The whole disk arrives at a Max Ct and that doesn't drop off significantly despite pulling harder (or trying to!) it just gets 'dirtier' and absorbs more energy/s it's one of the pretty things about a helicopter. It makes it 'docile' except for when the pilot thought he might be able to extrapolate his experience and pull out before the ground, and finds that embarrassingly and inconveniently he cannot
Anyway in the 'real world' they dont have a CA meter because it is rarely usefull for normal sensible handling, it's only relevant at 'the edges', where a pilot should take this concept into account anyway.
Punto
are you being serious or pulling my leg? (i might be getting oversensitive sorry) if a helicopter can pull 3g when light and Ctmax is reached (UCA is reached also) then the same helicopter when at heavy weight might reach Ctmax at only 2g but it will be about the same UCA.
So UCA would be more relevant than a g-meter for a helicopter.
If YOU want to suggest a CA meter then that's up to you, I'm not suggesting it, but it is a fair suggestion, I just think it would be interesting, and should be a fairly intuitive instrument in a helicopter.
Punto incidentally I'd like to thank you for engaging seriously and concisely i'm not particularly 'hung up' on this observation and am happy to receive sincere challenge to help me improve
as dc/da has rightly and fairly done
i think there is a serious point in there.
but the thread is 'Calling Nick Lappos etc' !!!!!! I don't blame him for checking out it is tedious and if i were he i would also have let this thread roll on alone but has he now understood the point?
