摘要：
In the case of a variable-pitch propeller or repeller according to the invention, the pitch-adjusting device is arranged in the hub and formed in such a way that it allows only a numerically limited number of different blade pitches, preferably just two blade pitches, for which purpose the pitch-adjusting device comprises an electrical drive device, for moving the blades from a first blade pitch to a second of the numerically limited number of blade pitches, and an electrically actuable locking device, for locking the blades in the numerically limited number of different blade pitches.
