THE DEVELOPMENT AND EVALUATION OF A RUDDER ROLL STABILIZATION SYSTEM FOR THE WHEC HAMILTON CLASS

A major thrust of recent research and development effort in surface ship dynamics has been in the area of ship/aircraft interfacing. This is due to the increased importance of helicopters and vertical/short takeoff and landing aircraft as the major combatant capability of nonaviation naval ships. One ongoing effort in the ship/air interface area is the joint U.S. Navy/Coast Guard Rudder Roll Stabilization Program. This program has been directed at using a ship's existing rudder(s) to control roll in a seaway. This report summarizes the steps taken to develop a rudder roll stabilization system for Coast Guard cutters of the HAMILTON Class, including a chronology of the problem encountered and the steps taken to overcome these problems. The performance features of this system for a wide range of operating conditions are documented, and critical design features and system limitations and benefits are identified. Preliminary results from the operational evaluation of two preproduction prototype systems indicate that the system, as designed, is very effective for short duty cycle utilization, such as in typical helicopter and vertical/short takeoff and landing aircraft operations. The system is also very effective at reducing roll over long periods of time, so as to increase habitability.
