Determination of Drag Coefficients for a Buoyant-Cable Antenna

Abstract

Samples of buoyant cable antennas of various lengths and surface roughnesses were towed over a range of speeds and depths in different wave conditions. Based on measurements of the forces developed and using computerized prediction techniques, normal and tangential drag coefficients were determined for the submerged segment of the BCA configuration and drag coefficients were determined for the floating length segment. The drag coefficients are presented in both tabular and graphical form. The results indicate that both coefficients. The results also indicate that the effects of cable stiffness on the accuracy of the cable catenary predictions require further investigation.
