Abstract

A band with an airfoil profile that follows a continuous path like a wave substantially in the plane of a virtual disc moving around the circumference between it and a common radial offset such that when the band rotates about the disc's axis the airfoil presents a largely common angle of attack to the fluid flow when moving between it's amplitude peaks and troughs made possible by the fact that at both the peaks and the troughs the upper surface and lower surfaces of the airfoil morph through a largely symmetrical transition to swap sides on the band. Or a band with an airfoil profile that follows a continuous path like a garter spring with it's axis moving around the circumference of a virtual disc such when the band rotates about the disc's axis the airfoil presents a largely common angle of attack to the fluid flow even as it moves around it's path between it's radial maxima and minima made possible by the fact that at both the maxima and minima the upper surface and lower surfaces of the airfoil morph through a largely symmetrical transition to swap sides on the band. Modifications to the chord, band path, airfoil section and angle around the path of the band can enhance it's ability to entrain more fluid and expel it more judiciously in order to increase it's effectiveness as a generator or propeller. The band can be retained about a central hub by spokes or cables or pylons or the tops of the waves can be connected to an external ring.
