An Investigation of the Towing Characteristics of the Deep Submergence Rescue Vehicle. Part I. Submerged Towing in Clear Water,

摘要

The submerged towing characteristics of the Deep Submergence Rescue Vehicle (DSRV) are examined for a variety of towpoints and ballast conditions. The results indicate that DSRV can be readily towed at speeds up to at least 15knots from towpoints located on the forward hard ring with vehicle net buoyancies from 0-2000pounds positive. The hydrodynamic downforce produced by the vehicle without additional appendages such as a depressor is sufficient to produce towing depths of 100-150feet with less than 500feet of submerged towline length.
