ABSTRACT:
There is presented an underwater body and intake scoop, the underwater body aving a wall defining a major portion of the body, the wall being exposed to water during movement of the body through a water environment. The intake scoop includes a recess in the wall of the body, the recess having forward and aft edges extending substantially width-wise of the body and interconnected by generally length-wise extending side edges to form, in plan view, a multi-sided recess with the side and aft edges being rounded to facilitate reduction of turbulence and cavitation. A bottom surface of the recess slopes from the forward edge inwardly of the wall. The recess is in communication with a conduit extending to the interior of the body.
