Title:
FLAPPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/110292
Kind Code:
A1
Abstract:
A flapping device (1A) is provided with a frame (10), an actuator installed on the frame (10), a pair of flexible wings (40) that generate lift by longitudinal oscillating movement, and cords (47) extended between the frame (10) and the pair of wings (40). Each of the wings (40) includes a leading edge (41) to which the oscillating movement is inputted from the actuator, and a trailing edge (42) that actuates later than the leading edge (41) with respect to the input of oscillating movement from the actuator to the leading edge (41), the cords (47) being connected to the trailing edges (42). The flapping device (1A) is furthermore provided with cord supports (53) that support the cords (47) on the frame (10) side, and a position adjustment mechanism (50) that variably adjusts the positions of the cord supports (53) by moving the cord supports (53). Due to such a configuration, there is provided a flapping device in which a mechanism for achieving various forms of flight is obtained by means of a simple configuration.
