This report gives details of a sea trial evaluation of the hydrodynamic performance and stability of a depressor-towed array system for the Office of Naval Research (ONR). For these hydrodynamic evaluations, a simulated towed array was used. Speeds of up to 30 knots were attained with no adverse effects of towline kiting. A depth of 75 m (245 feet) was obtained at a towline scope of 207 m (680 feet) at 30 knots. Dynamic performance was assessed during towship accelerations, decelerations, and maneuvers. The system responded very quickly to these speed changes and maneuvers and at no time gave any indication of instability. It was concluded that the ONR high-speed, depressor-towed array system is hydrodynamically stable up to at least 30 knots and is ready for high-speed acoustic evaluation. (Author)
