Abstract

The problems of harmonic oscillations and aperiodic wing motions are considered in the linear formulation. On the basis of the representation of the aerodynamic characteristics in terms of the rotary derivative coefficients it is shown that these coefficients are the same for the case of very low oscillation frequencies and the case of a linear variation of the parameters for aperiodic motion.
