| Popis: | A new formulation of the flutter equation allowing efficient solutions both by a continuation and a direct method is herewith presented. The continuation method differentiates the flutter equation with respect to the speed giving rise to a system of differential equations whose solution permits an easy and efficient tracking of the aeroelastic modes, frequencies and approximate dampings. If only the flutter point, i.e. its mode, speed and frequency, is required, a direct solution of the nonlinear algebraic system of the flutter equation is performed. Some examples of practical applications are briefly presented and discussed. |
