Variable camber fluid power machine

A variable camber fluid power machine for converting the kinetic energy of the moving fluid stream to a useful mechanical energy in the form of rotating motion with a torque, said variable camber fluid power machine comprising:

• (a) a central shaft having means for indexing the angular position of said central shaft about the axis of said central shaft relative to the fluid stream direction;
• (b) a plurality of arms extending axisymmetrically from said central shaft, said plurality of arms being rotatable about said central shaft;
• (c) a plurality of oblong blades, each of said plurality of oblong blades rotatably disposed to the extremity of each of said plurality of arms wherein each of said plurality of oblong blades is allowed to revolve about said central shaft and at the same time is rotatable about the center line of each of said plurality of oblong blades, said center line being generally parallel to said central shaft;
• (d) a first plurality of mechanical transmission means linking the rotating motion of each of said plurality of oblong blades about the center line of each oblong blade to the revolving motion of said oblong blade about said central shaft relative to said central shaft wherein each of said plurality of oblong blades rotates at an angular velocity equal to one half of the angular velocity of the revolving motion of said oblong blade about said central shaft wherein each of said plurality of oblong blades takes a position generally tangential to the revolving path of said oblong blade at the minimum drag position and takes a position generally perpendicular to said revolving path at the maximum drag position, said maximum drag position being diametrically located to said minimum drag position with respect to said central shaft;
• (e) a plurality of pair of flaps, each of said pair of flaps pivotably attached to each edge of each of said plurality of oblong blades, each of said flaps being pivotable about axis parallel to the edge of said oblong blade;
• and
• (f) a second plurality of mechanical transmission means linking the pivoting motion of each pair of said plurality of flaps to the rotating motion of each of said plurality of oblong blades wherein each pair of said flaps generally line up with said oblong blade to which said pair of flaps are attached, at 0 degree, 120 degree and 240 degree revolving positions about said central shaft, said revolving positions measured from said minimum drag position in the direction of the revolving motion of said plurality of oblong blades about said central shaft, and are deflected toward to one another at other revolving positions providing a camber to the blade-flaps assembly creating an additional lift force to generate a torque about said central shaft in the direction of the revolving motion of said blade-flaps assembly about said central shaft wherein the maximum camber is provided at 60 degree, 180 degree and 300 degree revolving positions, said revolving positions measured in said manner.
