Laminar flow underwater vehicle

摘要

A torpedo having a nose section wherein the entire nose section is of a porous material. The volume behind the nose is divided into a plurality of annular chambers and a fluid delivery system provides filtered sea water to the chambers for expulsion through the porous nose. The filtered water passing over the nose and torpedo body is at a rate to alter the trajectory of any particulate matter that would tend to destabilize laminar boundary layer operation.
