Abstract

An adjusting apparatus (9) for adjusting the pitch angle of propeller blades (1, 2, 3, 4, 5, 6, 7, 8) of a variable-pitch propeller - in a first blade pitch-angle range with positive pitch angles at which the propeller blades (10) produce thrust, - in a second blade pitch-angle range which includes in a third blade pitch-angle range with negative pitch angles, at which the propeller blades produce reverse thrust with the propeller rotating in the same direction, wherein the pitch-angle range in which the blade drag is a minimum, as well as a range of positive pitch angles with low thrust and a range of negative pitch angles with low reverse thrust, at least a first group (A) of the propeller blades (1, 2,...) can be rotated through the second blade pitch-angle range with critical pitch angles, while the propeller blades in another group (B) are in a positive blade pitch- angle range. Corresponding variable-pitch propeller computer- implentable control function and method are also described.
