  • Fin apparatus for controlling heat flux distributions
    Patent number: 4991530
    Abstract: A fin apparatus is provided for controlling heat flux distributions in a ted body, such as a torpedo. The torpedo may have inner and outer spaced apart shells with a predetermined ratio of conducting and nonconducting fins affixed to the shells in the space therebetween. In a torpedo it is desirable to establish the ratio so that heat will be distributed from the outer skin of the torpedo shell to improve laminar stability in the boundary layer as the torpedo travels through the water.
