Abstract
An array of axially spaced rotating airfoils having funnel strips on the blades to increase the lift to drag ratio and generate thrust are rotatably driven by small motors with rotating airfoils, also having funnel strips to enhance thrust. The small motors are mounted on the tips of one set of rotating airfoils, or on an auxiliary drive member, so as to provide rotational torque for the array, thereby amplifying thrust generated by the fluid motor.
