    Abstract: Method and apparatus for converting the kinetic energy of a moving fluid stream into useful work by using a cascade of thin aero or hydro foils positioned therein. The foils may be provided with at least two degrees of freedom and adjacent foils move out of phase. The foils are subjected to fluid induced oscillations known as flutter. Barriers (3, 43) may be positioned upstream, above, or at sides of the apparatus for increasing efficiency by increasing the fluid velocity. A system of flywheels (17, 18) are used to increase inertia of the foils and are particularly useful with hydrofoils. A cascade of aero or hydro foils may be mechanically oscillated to transfer energy to a fluid.

    Abstract: Method and apparatus for converting the kinetic energy of a moving fluid stream into useful work by using a cascade of thin aero of hydro foils (2) positioned therein. The foils may be provided with at least two degrees of freedom and adjacent foils move out of phase. The foils are subjected to fluid induced oscillations known as flutter. Barriers (3, 43) may be positioned downstream, above, or at the sides of the apparatus for increasing efficiency. A system of fly wheels (17, 18) to increase inertia of the foils may be used with the hydrofoils. A cascade of aero of hydro foils may be mechanically oscillated.

    Abstract: There is disclosed a method and apparatus for converting the kinetic energy of a moving fluid stream into useful work by means of a cascade of thin airfoils positioned therein. In one embodiment, the airfoils are provided with at least two degrees of freedom and adjacent airfoils are movable out of phase. The airfoils are subjected to the aerodynamically induced oscillations caused by the aeroelastic phenomenon known as flutter and the oscillatory movement is then harnessed to do useful work. In an alternate embodiment, a cascade of airfoils is mechanically oscillated within a moving fluid stream to increase the propulsion of the fluid. Where the fluid is a liquid, the cascade includes a plurality of hydrofoils.
