Prop Pitch Station Generator
Prop Pitch Station Generator
This utility will generate a series of values for angles at various distances
from the hub for propeller pitch calculations. Note that you may change the
increments for distance and pitch, as well as ranges of both.
The calculations for the angles at each station are based on the following formula:
a = 90 - DEG(ATAN((2pi*D)/P))
Where:
a = angle of station in degrees
D = Distance from center of propeller
P = Pitch of propeller
