A Novel Flapping Mechanism for 20cm-Wingspan Micro Air Vehicle

L J Yang


This paper presents a progressive iteration of monoplane flapping wing mechanisms in the past few years. The primary objective of the research was to create an efficient, low power, low volume flapping mechanism capable of producing lift force large enough to enable vertical take-off and landing (VTOL), with zero phase lag between the wings, large flapping stroke and
minimal transverse vibration. Three iterations of the mechanisms are presented here with problems pertaining to the primary objective progressively solved. The performance characteristics for each mechanism was evaluated based on various parameters and the final mechanism is believed to deliver the best performance for a sub 20 cm wingspan category of micro air vehicles (MAV).
