The invention relates to a device for converting wind energy into another form of energy comprising a plurality of propellers having equidirectional shafts, being arranged in a matrix and driving associated energy converters. The invention generally proposes to design a device of the kind set forth in a manner such that the occupation density is at least 0.4 propellers per square meter. By this step a device is obtained, whose propellers are so small that the profile can satisfy an ideal profile with great accuracy without excessive increase in productio...
1. A device for converting wind energy to mechanical energy, which comprises a rotatable driving shaft adapted to provide energy output, a propeller having a plurality of blades radiating from said shaft, each blade being of airfoil shape in cross section to define a rounded leading edge and a tapered trailing edge, each blade having an axis defined by the locii of points lying at the one quarter points of the chords of the airfoil which axis is curved from the root of the blade toward the tip in the direction of rotation, and the tip portion of each bla...
