Title:
ROTARY VARIABLE-DIAMETER FLAPPING WING
Document Type and Number:
WIPO Patent Application WO/2011/095117
Kind Code:
A1
Abstract:
A rotary variable-diameter flapping wing includes a framework structure (1) rotatable around its own rotating shaft, a sliding device (2) arranged on the framework structure (1) and flapping wings (8). One end of the flapping wings (8) is fixed on the framework structure (1), and the other end is fixed on the sliding device (4). A slideway (101) matching with the sliding device (2) is arranged on the framework structure (1). When the framework structure (1) rotates, the sliding device (2) slides on the slideway (101) so as to make the flapping wings (8) open or contract. Water power and wind power act on the wings (8). Since the wings (8) slide on the framework structure (1), the wings (8) swing up and down or rotates on the framework structure (1),so as to realize an unsymmetrical distribution in the radial direction and produce a wing flapping function. The transformation from wind power or water power into other energy is realized by a power transforming device (4). The rotary variable-diameter flapping wing realizes a low cost, a light weight and a high efficiency.
