Title:
VARIABLE FIN ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2011/083888
Kind Code:
A1
Abstract:
Disclosed is a variable fin assembly including a fin having a planar structure. The other portions of the fin aside from a fixed end are rotated or deformed, from the original positions of said other portions about said fixed end within a certain range in opposite directions, by means of the pressure of air or another fluid, such that the positions of said other portions are changed. A stopper may be disposed around the fin to limit the rotating and deforming of the fin to a certain extent when the fin is rotated or deformed by the pressure of air or another fluid. Thus, regardless of whether wind blows forward or rearward, force is applied to the fin in a constant direction, and the fin can be deformed according to the direction of the wind, thereby improving the efficiency of an apparatus using the variable fin assembly.
