Abstract: This article gives important guidelines for vertical axis wind rotor new designed active pitch control system aerodynamic force perturbations at pitch mechanisms and servo motor. For active pitch control system servo motor power calculation is important to have information about all possible loads on the system. The research main target is using experimental data find the aerodynamic force as function of blade pitch angle. The research was provided using new designed special servo test bench with experimental blade of NACA0018 profile. Experimental data analyse provides full information about possible aerodynamic force as function of blade pitch angle. Provided functions can be used in next researches about active pitch control system servo motor power calculation or wind rotor blade angle control methods. Main experimental research conclusion provides information that aerodynamic blade force to pitch system servo motor in range of pitch angle ± 20 ° is ≈ 0 Nm. In case if pitch angle is more than 20 ° then aerodynamic force is linear function of blade length and pitch angle.
Keywords: NACA0018, VAWR, aerodynamic force, blade inertia.
