EXPERIMENTAL DETERMINATION OF STRUCTURAL AND STILL WATER DAMPING AND VIRTUAL MASS OF CONTROL SURFACES

An experiment has been designed for determining the damping constants and virtual mass for the control surface systems of USS ALBACORE and USS SAMPSON; theoretical methods for determining the virtual inertias (including virtual mass) of these control surfaces are also given. The theoretical foundation for the experimental design and the procedure for analyzing the experimental data are described. The damping and inertial parameters obtained are essential to the performance of a hull-control surface vibration and/or flutter analysis. Test procedure is applicable to control surfaces of surface ships, submarines, hydrocrafts, etc.
