ABSTRACT:
A hydraulic jet propelling apparatus has an inlet opening at one end and an outlet opening at the opposite end for a fluid passing therethrough. Between the inlet and outlet openings, a centrifugal accelerator member defines a divergent annular passageway for the fluid, with a frusto-conical external sleeve and a frusto-conical central vaned rotor member keyed together on a driving shaft. A stationary cup shaped wall projects from an outlet of the accelerator member, an internal face of which, seen in axial section, having a curvature variable from the outlet of the accelerator member to define at an outer end thereof a straight direction substantially axial to said internal face. The internal face being provided with a plurality of vanes for guiding and progressively changing direction of the accelerated fluid from a diverging and rotative trajectory when leaving the accelerator member to a trajectory parallel to the straight direction when leaving the wall.
