Design of a Circulation Control Stern Plane for Submarine Applications
Abstract
This study was undertaken to design a non-deflecting circulation control (CC) submarine stern plane to provide maneuverability control and eliminate the possibility of catastrophic crash dives due to stern plane jamming. Symmetric elliptic sections with tangential blowing out of upper and lower slots over a rounded trailing edge were used because of their high lift and equivalent aerodynamic (hydrodynamic) efficiencies. The CC model stern plane so designed was restricted by the requirement to maintain the same planform as a conventional stern plane, by the existence of a large boundary layer on the main body, and by the additional requirement of zero deflection. With moderate blowing, it was able to meet or exceed the prescribed lifting (maneuvering) requirements for the conventional deflecting control surface. In the event of a blowing failure, inherent stability would result due to the fixed nature of the plane. The study contains a detailed design procedure; supporting experimental data; the final geometry of the blown model stern plane; and a similar study on an alternate blown configuration with end plates.
