  • Lifting body water jet propulsion inlet inductor
    Patent number: 7470161
    Abstract: A foil shaped lifting body is attached by means of a strut to the underwater body of a vessel in such a manner as to cause a standing wave to be developed when the vessel is in operation in order that the standing wave will induct water into machinery intakes. The technology of this invention is particularly applicable to the operation of waterjet marine propulsion systems.
