"This report develops and illustrates a natural modal transformation theory which is applicable to flexible spacecraft with damping and gyroscopic forces. The theory is arranged into a form which is a generalization of the classical normal modes transformation theory. Modal differential equations are given in terms of real-valued scalars. Block diagrams in the time and Laplace transform domains demonstrate the feed-forward and second-order filter characteristics of the structure of the equations. Results for a single-axis flexible dynamics example are compared with earlier published results to show the correlation with the classical normal modes transformation theory"--Abstract, page 1.
