The propeller further comprises an adjusting member (34), adapted to be displaced along a first dimension (L), and a transformation arrangement connecting the adjusting member to the propeller blade such that a displacement, in the first dimension, of the adjusting member results in a change in the pitch of the propeller blade. The transformation arrangement comprises a slot comprising a slot portion with a slot centre extending in a slot extension direction which direction is arcuate with a radius of curvature. The transformation arrangement further comprises a control element slidably engaged with at least the slot portion. |
