Methods for Predicting Tail Control Effects on Conical Afterbodies of Submersibles
Abstract
Methods were constructed for predicting the effects of all-movable tail fins mounted on a conical afterbody on the longitudinal stability and control characteristics of submersible vehicles. A set of wind tunnel tests were conducted to obtain systematic data as functions of tail fin aspect ratio, taper ratio, span-to-body diameter ratio and deflection angle and vehicle angles of attack and sideslip. These data were then used, coupled with theoretical results, to develop the prediction methods. The methods deal with the characteristics of individual vehicle components (bodies, tails) and their mutual interactions when combined into complete configurations. Each method is presented in self-contained form, along with appropriate directions for its use. It is shown that the methods provide good accuracy for prediction of hydrodynamic control characteristics.
