AERODYNAMIC HYSTERESIS OF OSCILLATING AIRFOIL
Original language description
In the aerodynamic calculations, the steady aerodynamic data, which contain the coefficients in form of a function dependent only on the angle of attack (AoA) are used. However, the airfoil aerodynamic characteristics are always unsteady in the real conditions at the same AoA can be different because of the time delay, which occurs in dynamic state. The unsteady approach can improve the aerodynamic calculation process of propellers and wind turbines in the yaw (in the crosswind) or helicopter rotors at high forward speed. This paper contains the results of wind tunnel test of the oscillating airfoil which demonstrate hysteresis properties of airfoil aerodynamics and the dependency of aerodynamic hysteresis on the angular frequency.
