Abstract
Presented is a lifting body ship that has a blower pressurized air layer disposed in the underside of its lifting body such that the air layer reduces wetted area friction and hence the propulsive power required is greatly reduced. Further, a water propulsor is supplied that takes in water through transversely oriented water inlets in the top of the lifting body to thereby reduce turbulence and its associated drag that would normally occur over the top of the lifting body.
Claims28
In an improved lifting body ship with one or more strut-like members that connect a lifting body to a hull of the ship, the improvement comprising:
- said lifting body having, as seen in a bottom plan view of the improved lifting body ship, at least in its majority a curvilinear shape with an artificially pressurized gas layer disposed in the underside of said lifting body.
In an improved lifting body ship with one or more strut-like members that connect a lifting body to a hull of the ship, the improvement comprising:
- said lifting body having, as seen in a bottom plan view of the improved lifting body ship, an artificially pressurized gas layer disposed in the underside of said lifting body and wherein a forward portion of the artificially pressurized gas layer is defined by a discontinuity in a lower surface of the lifting body and wherein said discontinuity, as seen in the bottom plan view of the improved lifting body ship, is at least in part curvilinear in shape.
In an improved lifting body ship with one or more strut-like members that connect a lifting body to a hull of the ship, the improvement comprising:
- said lifting body, as seen in a bottom plan view of the improved lifting body ship, being at least in part curvilinear in shape and having an artificially pressurized gas layer disposed in the underside of said lifting body and which further comprises a water propulsor at least in part disposed internal to the lifting body that takes in at least part of its water used for propulsion through one or more water inlets disposed over a top surface of the lifting body and wherein said one or more water inlets are transversely oriented over an upper surface of the lifting body.
