Abstract

The object of the invention is a device enabling pre- adjustment of a propeller blade 2, having a curved blade- profile mean chord, against the action of a torsion spring 8, through the action of wind forces tending through said form of the blade to rotate it around its longitudinal axis, and being independent of the lifting forces acting on the blade. The invention is characterised by a device forming a delimiting of the rotative movement of the blade in the sprung-back movement of the torsion spring 8, being placed outside relative to inter-rotatable tubular elements 6, 7, of which one is connected with the propeller blade and the other connected with the propeller axle and convoluting the torsion spring. <IMAGE>
