Methods for Predicting Submersible Hydrodynamic Characteristics

Abstract

Methods were constructed for predicting the hydrodynamic characteristics of submersible vehicles in pitching attitudes with undeflected tailfins. An extensive set of models was built, representing the geometries of a wide range of submersibles. These models were then tested in a wind tunnel to obtain systematic data over relevant ranges of attitudes and flow conditions. The 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 with their mutual interactions when combined into complete configurations. Each method is presented in self- contained form, along with directions for its use. It is shown that the methods provide good accuracy for prediction of hydrodynamic characteristics.
