Abstract (en)

[origin: WO2012084717A1] A device (60) according to the invention for generating a directed fluid flow comprises a support structure (1); a rotary structure (5) mounted so as to be rotatable relative to the support structure about a first axis of rotation (10); and at least one active element (61, 61') which is mounted on the rotary structure (5) so as to be rotatable about a second axis of rotation (9, 9') and which has an active surface (67). The at least one active element is operatively connected to the rotary structure and to the support structure such that, when the rotary structure rotates relative to the support structure by one revolution about the first axis of rotation in a first direction of rotation, the at least one active element rotates relative to the rotary structure by half of one revolution about the second axis of rotation in the opposite direction of rotation.
