Abstract

Variable propeller (1), in particular for marine vessels, comprising at least three individual propellers (2a-2e), arranged on a common shaft (3), the individual propellers (2a-2e) being arranged to rotate relative to each other about the rotational axis (3a) of the common shaft (3) such that several different helical flow channels (4a-4d) may be formed.
