Diameter of a typical fixed pitch propeller
WebMar 26, 2024 · Since FPV motors have similar specifications and designs in recent years, stator size is the simplest way to quantify torque. Stator size can be calculated using the volume of a cylinder formula: volume = pi * radius^2 * height. For example, a 2207 motor’s stator volume is: pi x (22/2)^2 x 7 = 2660.93. Webn is the propeller speed, ρ is water density, D is the propeller diameter, P/D is the pitch diameter ratio, Z is the propeller blades number, A E /A 0 is the blade area ratio, and R n is Reynold's number. K Q and K T are non-dimensional coefficients correlated with the propeller geometrical structure and are determined through open-water ...
