A WIND TUNNEL INVESTIGATION OF THE HYDRODYNAMIC STABILITY OF A MANNED UNDERWATER STATION IN OCEAN CURRENTS.

Abstract

The hydrodynamic stability of an underwater stations was studied using wind tunnel models. Rigid model force and moment coefficients were obtained for various orientations of the station in three dimensions. The unsteady motion of the station in cross currents was investigated with a dynamically similar model. Color 8mm pictures and amplitude-time traces of the unsteady motion were obtained. (Author)
