摘要： A wind turbine blade mounted to a hub of a wind turbine includes an airfoil portion disposed between a blade tip portion and a blade root portion configured to be connectable to the hub. The airfoil portion includes a leading edge which sweeps back from a blade axis direction at least in a sweepback region disposed on a blade tip portion side, and an angle A [degree] between the blade axis direction and a tangent line of the leading edge satisfies a relationship of A ≥ 250 x r/R -225 in a range of 0.9 ≤ r/R ≤ 1 in the blade axis direction. R is a distance from a rotational center of the hub to the blade tip portion in the blade axis direction, and r is a distance from the rotational center of the hub to a certain point on the leading edge in the blade axis direction.

摘要： The invention is entirely in keeping with the industry of renewable energies, particularly those using kinetic energy from fluids. The invention comprises the non-conventional design of the shape or geometry of a rotor blade, such rotor being or not being coupled to a machine which generates power from the transformation of kinetic energy that a fluid in movement has. The fundamental purpose of the design is to improve the efficiency in which fluid kinetic energy is transformed, thus being able to obtain better power coefficient values and therefore better performance when generating power. Said rotor must have as a minimum two (2) blades (e) for the operation thereof and is primarily designed for wind power generation applications.

摘要： Provided is a wind turbine blade that delivers the desired aerodynamic characteristics under conditions where the upper limit of the chord length near the blade root is limited. The wind turbine blade includes a blade body (3) whose chord length increases from a blade tip (1b) toward a blade root (1a). The blade body (3) includes a blade tip region (1c) located near the blade tip and whose chord length increases gradually toward the blade root (1a), the blade tip region (1c) having a substantially constant first design lift coefficient, a maximum-chord-length position (1d) located near the blade root (1a) and having a maximum chord length, the maximum-chord-length position (1d) having a second design lift coefficient higher than the first design lift coefficient, and a transition region (1e) located between the blade tip region (1c) and the maximum-chord-length position (1d). The transition region (1e) has a design lift coefficient increasing gradually from the first design lift coefficient to the second design lift coefficient in a direction from the blade tip (1b) toward the blade root (1a).

摘要： An electrical power generator assembly (10a) for using kinetic energy from a flowing fluid (12) to generate electrical power. The electrical power generator (10a) includes a blade assembly (14) and at least one primary coil (52). The blade assembly (14) having a head end (16) for facing incoming flowing fluid (12), a tail end (18) spaced from the head end (16) for facing in the direction of the flowing fluid (12), and a rotational axis (20) extending between the head end (16) and the tail end (18). The blade assembly (14) includes a blade arrangement (44) which is arranged in generally helical fashion about the rotational axis (20), and at least one mounting formation (26, 36) connected to the blade arrangement (44). Each mounting formation (26, 36) is adapted to permit mounting of the blade assembly (14) for rotation about its rotational axis (20), so that in use fluid flowing past the electrical power generator assembly (10a) interacts with the blade arrangement (44) to rotate the blade assembly (14) about its rotational axis (20). The at least one primary coil (52) is connected to the blade arrangement (44) for rotation with the blade arrangement (44). The at least one primary coil (52) is energizable and being arranged in use to interact with at least one stationary secondary coil (54b) to generate electrical power in response to rotation of the blade assembly (14).
