Abstract

A method where a propeller is set into locomotion relative to a medium at least partially surrounding the propeller. An actuator induces a rotation of the propeller relative to the medium and about a rotational axis of the propeller, and the propeller converts its rotational movement into locomotion relative to the medium. The aspect ratio of at least one cross-section of the propeller is three or more. Also a helical or modifiedly helical propeller for converting rotational movement of the propeller into locomotion of the propeller relative to a medium at least partially surrounding the propeller, where the aspect ratio of at least one cross section of the propeller is three or more. And a method of producing a propeller, including the step of providing a plate extending along the helical axis, where the aspect ratio of at least one cross section of the plate is three or more.
