A PRELIMINARY STUDY OF THE EFFECT OF THE FREE SURFACE ON THE DRAG OF A TRUNCATED 2:1 ELLIPSOID,

Abstract

The study of the drag force on truncated, axisymmetric, supercavitating bodies near a free surface involved the design, construction, and checking of the apparatus and instrumentation necessary to conduct the experiments. A truncated 2:1 ellipsoid at zero angle of yaw was chosen for the initial investigation. The drag of this body at zero angle of yaw was measured and compared with existing data for a 2:1 ellipsoid completely submerged. In addition, some preliminary work concerning the effect of the proximity of the free surface was performed.
