Abstract
A propelled cable fairing system for towing objects underwater having a plurality of cable fairings, which are individually propelled by motorized propulsion to avoid the thrust of propellers to overcome normally encountered drag heretofore utilized, which required use of longer and thicker cables resulting in a loss of control over the position of the towed object. In addition, the relative position of the propelled cable fairing system is maintained through a set of serially linked motor controllers that sense the relative position of each propelled cable fairing relative to it adjacent propelled cable fairing. Variation in position of the propelled cable fairing from a target, causes increase in speed of the motor or alters its angle of attack in order to keep the propelled cable fairings in predetermined alignment with the adjacent cable fairing. By use of a plurality of rudders, the propelled cable fairing system allows the operator to maintain the towed object at desired horizontal and vertical positions.
