Phase lag
To Nodrama
It seems i may have inadvertantly opened a whole new can of worms here, I was led to believe throughout my training that phase lag is the phenomenon where "a cyclic input causes the disc attitude to change, the blade reaching its highest and lowest 90 degree later than the point where the maximum increase and decrease of pitch are experienced" and that this 90 degree delay was due to the principle of gyroscopic precession.
I was also told that phase lag was always 90 degrees and that it was the advance angle to overcome this problem that could be varied.
From what your saying clearly this doesn't seem to be the case, could you please elaborate or point me in the direction of some decent notes? As i'd quite like to know both sides of the story
Cheers
