Abstract: The present invention relates to a fluid propulsion system having an outer shell which provides bearing support, ducting and streamlining for a hollow inner propulsion rotor. The rotor includes vanes having a plurality of blade sections which are supported and evenly spaced on an inner surface of the rotor parallel to the rotational axis. Rotation of the rotor with respect to the outer shell draws air/gas into the fluid medium via a venturi effect. The blade sections are designed so as to maintain contact with the fluid molecules passing through the fluid propulsion system and thus is able to provide additional energy to the molecules which are already placed in motion by the blade sections.
