Abstract

Two different types of towed vehicle, EIKO and DRAKE have been developed to house an ADCP (acoustic Doppler current profiler). EIKO is a simple and stable vehicle without any mechanism for the motion control. The depth and roll of DRAKE are controlled by the main wings and horizontal tail wings. The contours of EIKO and DRAKE are designed so as to increase the hydrodynamic damping force and t o decrease the unstable roll moment acting on them. Structures of the two vehicles and results of on-site experiments for confirming their performances are described. The experiments showed that EIKO and DRAKE with ADCP are suitable for measurements of the ocean current.
