Abstract : The report presents the development of a dynamic response prediction method based on the transformation of classical flutter analysis solutions. The development is accomplished through investigation of the equations of motion of the flutter system for the determination of relationships of this system which are also common to the dynamically responding system's equations of motion. Several special operators were discovered to relate these two systems. Theodorsen incompressible aerodynamics and Ackeret's source pulse aerodynamics were used in the development of the dynamic response prediction method. As a result of these efforts, the analyst may now predict an aeroelastic system's dynamic response in a manner independent of system basic parameters by merely transforming the solutions of a simple-harmonic-motion, required-structuraldamping flutter analysis.
