Title: HELICOPTER ROTOR HEAD, MULTIROTOR HELICOPTER, AND HELICOPTER
Abstract:
The present invention configures a variable pitch mechanism for helicopters, which has a simple configuration having a reduced number of components, and which is capable of precisely controlling the pitch angle of blades even without an accurate adjustment. A pitch plate 16 and a pitch plate boss 17 are slidably mounted on the outer periphery of a main mast 61, and the output shaft of a servomotor 19 is directly connected to a pitch lever 18 that vertically moves the pitch plate boss 17. When the servomotor 19 is actuated and the pitch lever 18 is rotated, the pitch plate boss 17 and the pitch plate 16 are displaced upwardly or downwardly along the main mast 61, thereby tilting blade holders 13 connected to the pitch plate 16 and changing the pitch angle of the blades 14.
