Traditional wind engine rotor includes a vertical shaft and at least two vertical wing-shaped blades connected with the shaft, which are symmetrically located about the shaft rotation axis. In the newly-developed design, each blade is tied with the shaft through the profiled upper and lower semi-wings located in the common vertical plane passing across their longitudinal axes and installed at an acute angle to the shaft and blade, respectively. The root parts of the semi-wings are fixed to the shaft by means of fixtures and are spaced apart in the vertical plane. The ends of the semi-wings are connected through docking joints with the blade and are spaced apart in its vertical plane, forming the upper and lower blade consoles and articulated wing with a closed trapezium-shaped power frame.

Several modifications of the rotor design are also proposed.

1. In this modification of the design, the junction of the upper and lower semi-wing with the shaft and the blade, respectively, forms the articulated wing whose closed power frame resembles an unequal-sided trapezium.

2.In this modification of the design, the similar junction of the same elements forms the wing whose closed power frame resembles an equal-sided trapezium.

3.In this modification of the design, the distance between the fixtures used to fix semi-wings to the shaft is higher than the vertical distance between the docking joints wherein the semi-wings and the blade are linked.

4.In this modification of the design, vertical distance between the fixtures used to fix semi-wings to the shaft is lower than the distance between the docking joints wherein the semi-wings and the blade are linked.

5,6,7. In these modifications of the design, various profiles of the semi-wings are described.

8.In this modification of the design, rotor is equipped with all-moving aerodynamically-profiled end shields. Each shield in connected in its root part with the blade central part and is capable to turn from a horizontal to a vertical position about its longitudinal axis.

9.This is the modification of the previous one (pos.8); unlike the 8^th modification, here an additional vertical wing blade is rigidly fixed at the tip of each shield.

10.In this modification of the design, the additional blade described in the 9^th modification is designed as Whitcomb’s wing.

11, 12, 13, 14 In these modifications, various designs of the shield mentioned in pos. 9 are described.

15.In this modification of the design, an automatic rotor speed control system which ensures synchronous turning of the shields about their longitudinal axes and an actuator kinetically linked with the rotating mechanism of each shield are provided.
