Experimental Investigation of Dual T-foil System on the Pitch Motion Reduction of a Monohull Vessel
As a vessel navigates at high speeds in waves, considerable pitching motion can result in the discomfort of passengers. In this study is proposed a ride control system consisting of dual T-foils to generate a larger righting moment than a common single T-foil system. One T-foil is mounted at the bow, and the other at the stern. Accordingly, different control strategies for dual T-foils were proposed To verify the stratigies, a model experiment was conducted in the Towing Tank, Dalian Unievrsity of Technology. The optimal control signal was determined by comparing the pitch responses, heave responses, bow accelerations, and stern accelerations of a vessel in regular waves. In addition, the control strategy for the best motion-reduction effect was investigated. The optimized dual T-foil system provides a 34% reduction in pitch motion.
