Roll control of submarines
MetadataShow full item record
The use of differentially deflected fairwater planes to control submarine rolling is studied. Because of coupling between pitch and roll angles, the snap roll that occurs in a high speed hard turn affects the stability of a submarine not only in the horizontal plane but also in the vertical plane. Direct roll control was achieved by making use of the fairwater planes in a differentially deflected mode such that they could give counter moment to reduce the snap roll. A roll controller was designed as a position and velocity feedback controller. Controlled roll angle improved the depth and pitch stability of submarine.
