Abstract:

A method has been previously published, with algebraic proof, for the approximation of the motion decay coefficients of aeroelastic systems from their conventionally computed required damping coefficients. Results found by this method, for many combinations of conditions, are compared with exact results found by otherwise less satisfactory methods. Recent refinements of the original technique are presented. The decay-damping relationship proves extremely accurate in most instances. Large errors prove to be strongly correlated with certain parameters of the solution, forming dependable error indicators within the method. The decay-damping transformation extends the conventional flutter solution technique into a full predictor of classical system response the present report completes a series of reports introducing this method for general use.
