Nonlinear Dynam. 2012;7(2):024501-024501-9. doi:10.1115/1.4005473 Figure Legend: Using the analytical forms (4), (6), and (3), this figure plots the variation of the cyclic pitch angles of a main blade in a function of the azimuth angle. The control commands are recorded from a commercially available R/C (remote control) transmitter (JR PCM9XII). Then, the collected input data goes into the derived analytical forms so as to obtain the resultant cyclic pitch angle at an azimuth angle.
