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.
Claims7
In combination, an underwater body and an intake scoop,
- said underwater body having a wall defining a major portion of said body, said wall being exposed to water during movement of said body through a water environment;
- said intake scoop comprising a recess in said wall of said body, said recess having forward and aft edges extending substantially width-wise of said body and interconnected by generally length-wise extending side edges to form, in plan view, a multi-sided recess, said side and aft edges being rounded, a bottom surface of said recess sloping from said forward edge inwardly of said body;
- said underwater body having interior portions forming a conduit of rounded cross-section and extending inwardly of said body, said recess being in communication with said conduit;
- and
- said recess having side walls diverging from each other between said forward and aft edges to provide for high-volume entry of water and extending aft beyond and beneath said aft edge, and converging aft of said edge to points of tangency of said conduit, whereby to provide pressure head at an entrance to said conduit.
