초록

Method and apparatus for reducing torpedo drag in which polymer drag reducing material is carried by the torpedo in concentrated form, ambient water is ingested and mixed with the concentrated polymer to produce a seawater-polymer solution of predetermined concentration, and the solution is ejected from the torpedo nose to be swept rearwardly in intimate contact with the exterior surface of the torpedo under torpedo forward motion.

청구항

A method for reducing skin friction drag associated with high Reynolds-number turbulent flows adjacent the surface of a torpedo, said torpedo being of a type having an elongated body and adapted to be self propelled through the water, said method comprising the steps: (a) ingesting a continuous flow of ambient seawater, (b) adding to the flow of ingested seawater a quick solvation, polymer-amorphous suspension mixture, said mixture containing a powdered form of hydrodynamic drag reducing water soluble polymer material having a high molecular weight and a...
