Results of Experiments With a Segmented Model to Investigate the Distribution of the Hydrodynamic Forces and Moments on a Streamlined Body of Revolution at an Angle of Attack or With a Pitching Angular Velocity
Abstract
The hydrodynamic forces and moments which are developed on unappended streamlined bodies of revolution at small and large angles of attack or with a pitching angular velocity were investigated by captive-model experiments and by theory. The captive-model experiments were performed with a segmented model of a Series 58 body in the deep water basin of the David Taylor Model Basin and on the rotating arm. Exact and simplified potential flow theories were used to compute the hydrodynamic force distribution on Series 58 bodies, and comparisons were made with the experiments. An empirical method was developed to predict the static and rotary stability derivatives for unappended bodies.
