The blades include first-type blades and second-type blades, the second-type blades having a different shape from the first-type blades.

The hub includes primary fan blades and splitter blades disposed between pairs of the primary fan blades.

The rotary blade body includes a blade support pipe and rotary blades.

The stationary blade body includes support rims, stationary blades, and elastic parts.

In a possible variant of the embodiment, the blades are provided with shaped grooves formed within the borders thereof.

Each of the blades is provided with channels.

A blade system for capturing wind power includes blades (21) and blade brackets.

Blades (5, 6), are pivotally mounted on the blade carrying assembly (3).

The blades are provided with movable baffles (23) that can close or adjust the tilt of the blades.

In other embodiments, the impeller is equipped with two sets of blades, which include primary blades and secondary blades.

Pivoting of the turbine blades takes place simultaneously with the pivoting of the control blades.

The positioning of the blades is accomplished by an actuator which is attached to the shaft of the rotatable blades.

The fan blades (21) include fan blades (21A-21E) having different cross-sectional shapes.

Blade Tracking and Vibration Analysis

The blade rotating cranks (5) are mounted on the one ends of the blade rotating shafts (4) away from the blade seat assemblies (3).
