DETAILED EXPLANATION OF THE INVENTION

[0031] Alternatives selected for this detailed description of the product subject to the invention are described only to ensure a better understanding of the subject and in a way that will not create any limiting impact.

[0032] The invention relates to a three-propeller counter-rotating wind turbine that is used to obtain electrical energy by benefitting from wind power in windy and high wind potential environments, and that needs a smaller installation area compared to conventional wind turbines that are currently in use, and that nevertheless has higher production capacity, as well as increased productivity, and that does not employ gears, and that has a direct drive mechanism.

[0033] The product subject to the invention, in general, includes minimum one rear blade group (104) composed of minimum five blades, minimum one front blade group (106) composed of minimum seven blades, minimum one central blade group (105) placed between rear blade group (104) and front blade group (106) and composed of minimum nine blades, minimum one third rotor (109) that is linked to the rear blade group (104) and turns counter-clockwise, minimum one second rotor (108) that is linked to the central blade group (105), turns clockwise, and passes through the third rotor (109), minimum one first rotor (107) that is linked to the front blade group (106), turns counter-clockwise, and passes through the third rotor (109) and the second rotor (108), minimum one counter-rotating generator (103) whose stator is revolved by the first rotor (107) and the third rotor (109) and whose rotor is rotated in the opposite direction by the second rotor (108), minimum one propeller housing (101) in which the front blade group (106), the rear blade group (104), and the central blade group (105) are contained and rotate, minimum one nacelle (102) that contains the whole mechanism on its body, and minimum one tower (100) that carries and lifts the whole structure.

[0034] Blades found in the front blade group (106), the rear blade group (104), and the central blade group (105) have preferably an angle of 60 degrees.

[0035] The first rotor (107) and the third rotor (109) connected to the front blade group (106) and the rear blade group (104) rotating with the effect of the wind directly turn the stator of the counter-rotating generator (103) while the second rotor (108) connected to the central blade group (105) rotating in the opposite direction of the front blade group (106) and the rear blade group (104) turns the rotor of the counter-rotating generator (103). No gear system is used in transmitting the rotational motion achieved from the wind to the counter-rotating generator (103), so the counter-rotating generator (103) whose rotor and stator are driven directly in opposite directions can efficiently generate electrical energy. Wind power can be utilized effectively thanks to a large number of blades in the front blade group (106), the central blade group (105), and the rear blade group (104). Based on these facts, the amount of electrical energy obtained per unit installation area can be kept at higher levels compared to conventional wind turbines, and electrical energy production costs can be reduced.

[0036] The number and angles of blades in the turbine can be altered to adjust turbine performance at an appropriate and desired level according to meteorological data relating to each installation area.

[0037] The product subject to the invention may be installed with or without the propeller housing (101).

[0038] In an alternative structuring of the invention, the first rotor (107), the second rotor (108), and the third rotor (109) are disconnected in order to reduce energy losses at the highest level, and the front blade group (106), the central blade group (105) and the rear blade group (104) are directly connected to the body of the counter-rotating generator (103).
