The purpose of this paper is to do preliminary work to design and test a flapping wing four-bar mechanism. A four-bar linkage system kinematic analysis is introduced forequation of motion of flapping wing. A validation case is selected upon the works of Konkuk University [4]. The type of mechanism is double rocker and the motion has a single-degree of freedom Four-bar mechanism is activated by a servo motor (ART-TECH AS-100) which is driven by Arduino Uno. Two different deflections (10° and 20°) for input angle θ1is analyzed and instantaneous aerodynamic forces are obtained in hover mode. From the design of four bar mechanism input angle of 10° result a flapping angle (φ) of 41.5° at 11.2 Hz flapping frequency. The maximum flapping deflection of the current mechanism is found to be 85.9° with 20° input angle and the flapping frequency attained with the servo motor is 5.85Hz. This paper provides a detailed description of the design and manufacture of the mechanism and experimental setup. A CFD analysis is also performed for 10° deflection angle of the flapping wing mechanism designed and tested.
