PURPOSE: An aerogenerator is provided to synchronously control the tilt angle of each blade, thereby improving control efficiency and operability. CONSTITUTION: An aerogenerator includes a nacelle part(200), a hub(300), multiple blades(400), a main shaft(500), a moving shaft(600), a link part(700), and a connecting part(800a). The moving shaft is capable of linearly moving inside the hollow main shaft, and the blades are coupled to one side of the moving shaft. The link part between the moving shaft and the blade axially rotates the blade according to the linear movement of the moving part in order to vary the tilt angle of the blade. The connecting part inside the main shaft includes a hydraulic generator(830), an actuating cylinder(810), and a piston(820). The actuating cylinder is connected to the hydraulic generator, and receives a hydraulic pressure from the hydraulic generator. The piston is capable of moving inside the actuating cylinder, and is coupled to the moving shaft. |
