摘要：The present invention is directed to a propeller and housing arrangement which is capable of (i) delivering propulsive thrust in any selected direction perpendicular to the axis of rotation and (ii) developing a concomitant lift force along the line of the axis of rotation. This is achieved basically by the utilization of an impeller or rotor having both centrifugal and centripetal blade surfaces, as well as screw type propeller blade surfaces. The proportion of lift to thrust is a function of the design of these rotor surfaces, and the direction of the thrust is determined by the design of the housing configuration and its alignment relative to the rotor. The present invention may be positioned on a vessel with its axis of rotation vertical, horizontal or canted and may also be designed to reverse the direction of thrust by using adjustable inlets and outlets, reversing the direction of rotation of the rotor or by changing the position of the rotor relative to the inlet and outlet.
