Abstract
Foil elements capable of generating lift forces and converting such forces into rotational movement of a body are suspended and submerged in a flowing stream or fluid current. Control means are provided to cyclically regulate the angles of attack of the foil elements in relation to the fluid current and to maintain substantially constant lift forces throughout a rotational cycle. Power take-off and/or generating means is included in the system.
Claims10
An apparatus for utilizing the energy in a fluid stream comprising a pair of anchorage means in fixed positions spaced apart transversely relative to said stream, elongated suspension means spanning said stream transversely of stream flow and having a pair of end portions, each end portion being attached to a said anchorage means, at least one lift foil element attached to said suspension means and being aligned therewith submerged in said stream and thereby extending transversely of said stream flow, and useful power generating means connected with and driven by movement of said lift foil element responsive to forces induced thereon by the moving stream.
