Document Type and Number:
Japanese Patent JPH089358
Kind Code:
B2
Abstract:
The present invention provides for a propulsion apparatus for fluid medium comprising an open-ended sleeve having an inlet and outlet for flow through of fluid and a series of cooperating blades positioned along the sleeve. Each of the blades has a leading and trailing edge and the blades are fixed to rotate with the sleeve and cause a progressive acceleration of fluid from the inlet to the outlet with rotation of the sleeve thereby providing thrust for propulsion. The blades cooperate to define a fluid path to accelerate a fluid from the inlet to the outlet to thereby provide thrust for propulsion as the sleeve is rotated. The apparatus of the present invention provides forward and reverse speed of propulsion independent of the speed and rotation of the driving mechanism whereby adjustment of the blades at a fixed speed accelerates or decelerates the propulsion effort.
