Abstract

The invention relates to a propulsion device comprising a hub and a plurality of blades, each blade having a portion thereof directly or indirectly attached to said hub, said blades having a generally concave shape, which in operation approximates the radial and eccentric path of a unit of liquid or gas flowing thereon whereby said unit of liquid or gas leaves said blades in a substantially axial direction. <IMAGE>
