Abstract
The application of a continuation method to the solution of a system of nonlinear flutter equations is presented. For practical analysis of complete aircraft a modal reduction is proposed, which is based on normal modes of the structure with all concentrated nonlinearities replaced by linear springs. In the solution process the stiffness matrix is modified by proper values resulting from harmonic balance. Results are given for a two-degree-of-freedom airfoil with nonlinear pitch stiffness and for a sailplane with several nonlinearities in the control system.
