New Flapping Mechanisms of MAV “Golden Snitch”

Lung-Jieh Yang, Chieh-Ming Cheng, Yi-Wei Chiang, Fu-Yuan Hsiao

Abstract


The flapping micro-air-vehicle (MAV) “Golden Snitch” developed by Tamkang University has a wingspan of 20 cm and the total mass less than 10 g. The maximum flight endurance has been extended to 8 min, and the flapping frequency can be up to 18.5 Hz. Regarding hummingbirds’ hovering capability as the final goal of flapping MAVs, two folds of modification have been made. The linkage dimension has been adjusted to generate larger flapping stroke angle at first. Secondly the authors added an elastic spring to replace the second rigid linkage in the flapping mechanism and to reduce the phase lag between two wings. A first trial of modifying the flapping mechanism with the flap stroke angle from 53 degrees to 68 degrees and minimizing the phase lag between two wings from 3 degrees to zero was shown in this paper.
