Abstract
A blade system, has rows of blades extending radially outward along the length and around the circumference of a rotor of a low-profile ground-mounted wind turbine which is particularly suited for use in remote locations. The wind-engaging end of each blade is arc-shaped and is turned about 120 degrees to maximize efficiency. Preferably, two rotors having the unique blade system are connected to a single, centrally located generator, and the entire unit is mounted on a frame which is rotatable on wheels about a central shaft. Further, a circular track is provided in for engaging the wheels for ease of rotation of the unit either under the direction of a PLC or in yaw.
Claims26
A blade system for a fluid turbine comprising:
- a rotor mounted for rotation about an axis;
- and
- a plurality of blades supported in rows along a length and having a blade axis extending radially and each row being spaced about a circumference of the rotor,
- wherein each blades is formed having a first attachment end for connection to the rotor and a second free end having an arcuate face, a plane of a chord of the arcuate face being rotated about the blade axis at an angle relative to the rotor axis.
A blade for a fluid turbine comprising:
- a first end for connection to a rotor of a fluid turbine;
- and
- a second free end having an arcuate face so as to maximize fluid engagement.
