The extent of dissymmetry is airspeed dependent. When you push the stick forward, you can change/adjust the system to a new steady state accordingly, but there will be cyclic variation in the angle that automatically happens without pilot intervention at any fore-aft stick position / airspeed combination. Teetering or flapping (choose your term depending on how many blades you have) does this.Now I’m getting confused. If you moved the cyclic forward such that the rotor head tilted 1° forward, that would decrease the pitch on the advancing blade (Eg from nominal 2° back to 1°) and conversely increase the pitch on the retreating blade (Eg from the nominal 2° up to 3°). Now you have 1° pitch on the advancing blade and 3° on the retreating blade. Would this not correct for the “dissymmetry” of lift?
I’ve got a feeling that we’re overlapping two different rotor behavioural characteristics here.
