EXPERIMENTAL STUDY OF LOAD ALLEVIATION WITH PASSIVE ADAPTIVE CAMBER AIRFOILS

We present the Passive Adaptive Camber (PAC) airfoil, a purely passive concept for unsteady load alleviation. Wind tunnel tests confirm load reduction, and show that the alleviation rate collapses when organized by the Cauchy number. This provides transferable, dimensionless design guidance for load-sensitive systems such as wind turbines and aircraft.
