Difference between Helix and Blade angle?!?!?
Bit stuck with this one. Pooley's book explanation is difficult to understand. Can anyone explain this to me in plain English?

Blade Angle is between the chordline and the plane of rotation.
Angle of Attack is between chordline and relative airflow.
Helix Angle = BLade Angle - Angle of Attack
Helix Angle + Angle of Attack = Blade Angle.
Angle of Attack is between chordline and relative airflow.
Helix Angle = BLade Angle - Angle of Attack
Helix Angle + Angle of Attack = Blade Angle.
