Hi ya'll,
I keep seeing info indicating rotor blades change angle of attack
during rotation and or change the angle when they articulate.
The articulate portion is hard to understand considering the
blades are mechanically attached at a given angle.
Raising the tip does not change the mechanics?
The blades can hardly (same reason) change their angle to the
rotor plane of rotation?
The rotor itself flys at an angle of attack to the line of flight.
There are four spectrums of rotation> forward, advancing, rearward and retreating.
It would seem the blades do see a change of angle to the line
of flight such as>
Advancing> rotor angle plus or minus blade incidence.
Forward> blade incidence only
Retreating> minus rotor angle and plus or minus blade incidence
Rearward> blade incidence only
Does any of this hold water and or make common sense?
If anyone has definative ideas would appreciate personal input,
OK?
