Patent ID: 7241106

Claim:
A boundary layer propulsion apparatus for use in transferring a fluid from a first location to a second location utilizing a tubular flow conduit armature located within a confined space with at least one inlet and at least one outlet which includes: a. a centrifugal volute casing having a first and second side walls and an outlet extends between the first and second side walls; b. at least one inlet passages coupled to a side wall of the volute casing; c. a rotor comprising: d. a movable tubular flow conduit armature positioned inside said volute casing and in fluid communication with the said inlet passages; e. a driven shaft coaxial with and located adjacent to one end of the tubular flow conduit armature, the driven shaft comprising a first blunt end coupled to a motor, and a second conical shaped free end; a plurality of first impeller blades extend radially from the second conical shaped free end toward the one end of the tubular flow conduit armature and coupled to the inside surface of the tubular conduit at the one end; f. an idler shaft coaxial with and located adjacent to the other end of the tubular flow conduit armature, the idler shaft having a second blunt end and a second conical shaped free end, a plurality of second impeller blades extend radially from the second conical shaped free end toward the other end of the tubular flow conduit armature and coupled to the inside surface of the tubular conduit at the other end; g. a plurality of axially spaced solid boundary layer disks attached to the outside surface of the tubular flow conduit armature; h. a plurality of manifold ports formed through the outer surface of the tubular conduit between adjacent axially spaced between said boundary layer disks; wherein the driven and idler shafts each is supported by at least one bearing disposed in a bearing housing attached to the outside of a respective side wall of the volute casing; the bearing housing further comprises seal means to prevent leakages; wherein the inlet fluid from a first location flowing into the inlet passage(s), under pressure generated by the pitched impeller blades, accelerates into the tubular flow conduit armature, exits through the plurality of manifold ports into spaces between said plurality of flow generating disks into the inside of the volute and moves radially outward in a spiral path to the outlet(s) due to the centrifugal force imparted through boundary effects of cohesion by said plurality of axially spaced disks and exits to a second location.
