摘要

The device (1) has a rotor shaft (3) connected with a rotor head (5) and driven with a motor (2). A wobble plate (8) has a stationary part (10), which is axially movable using an actuating unit (11), and a rotary part (9) that is rotatably supported opposite to the stationary part and is connected with a rotor blade (7) to rotate the blade. Another wobble plate (13) with its rotary part (14) is connected with the head, where the latter plate with its rotary part is connected with the blade in a flexible manner over control rods (17), and the latter plate is arranged around the former plate.
