An equation of missile motion in the pitching plane was found, assuming a non-linearity in aerodynamic stiffness in the form of a cubic term. An iterative method for approximating the angle-ofattack response to a step displacement of elevator angle was formulated. The results of applications of this method were compared with computer solutions; convergence of the approximations was demonstrated. A simple feedback control system was designed, and the iterative method was extended to the case of a control system step input. The method was thought to have limited practical value because of the labor required in using it.
