A root locus method for examining the influence of structural coupling on the stability of uncontrolled airplanes is presented. This graphical technique permits a rapid but accurate quantitative evaluation of the effects of changes in aeroelastic and aerodynamic characteristics on airplane stability. Specific examples will illustrate the utility of the method. Problems involved in integrating a flexible vehicle into an automatic flight control system are also discussed. The similarity of the problem as it exists in manned airplanes and multi-stage missiles is presented. Examples are shown which illustrate the conventional (linear control) design approach to this problem. A promising new approach utilizing adaptive (non-linear control) techniques is also presented.
