The calculation formula of the spiral:
\(p=√[ \frac {l^2}{n^2} - π^2d^2]\)
\(l=n√[p^2+(πd)^2]\)
In the formula:
n - the number of spirals
P——pitch
l——Spiral length
D——parameter
Spiral: In the plane polar coordinate system, if the polar diameter ρ increases (or decreases) proportionally with the increase of the polar angle θ, the trajectory formed by such a moving point is called a spiral.
The most common spirals are Archimedes spirals, logarithmic spirals, and hyperbolic spirals.
Pitch, the axial distance between the corresponding points on two adjacent teeth on the thread.
Pitch in RC/helicopter model: The distance of the spiral formed by one revolution of the same blade during the rotation of the propeller.
