“…Bhowmik et al 7 designed a flight prototype of 50 cm long wingspan, which includes an integrated gear box along with four bar mechanism, whose lift generation capability was improved by flapping and twisting operation. Kumar et al 8 proposed a prototype of black headed Gull comprising servo powered mechanism. A wingspan of 0.9 m was considered to produce less drag with increased wing area and aspect ratio.…”

A rich development in the domain of flapping wing Unmanned Aerial Vehicle (FWUAV) is not yet entirely sufficient to implement the findings of real-life situations. Using the limited knowledge of this domain, this work enlightens the scientific community by introducing a homegrown, patented flapping mechanism of foldable wing aerial vehicle. The synchronized dual wing flapping mechanism consists of a crank slotted lever, a gear train and a special type of 4 bar kinematic chain. The entire sets are powered by a DC motor through crank connected motor shaft. Flapping cycle works on quick return principle generated by crank slotted lever mechanism and foldable wing structure by the special type 4 bar chain with gear train ensure the controlled flapping frequency, twist angle, altitude gain and attitude parameters (Pitch, roll, yaw). This work majorly focuses on the kinematics of the developed bio mimic mechanism by observing the variation of flapping wing orientation, angular velocity and angular acceleration with respect to the crank rotation as well as different crank speeds. These analytically obtained kinematic parameters are further validated after developing a three-dimensional model of the said mechanism as well as multibody analysis by MSC ADAMS. The patterns of the kinematic parameters such that angular displacement, angular velocity and angular acceleration between output and input links are similar and its validation guarantees the correctness of developed mechanism. The kinematic analyzes of linkages are also essential for dynamic study as well as fabrication of prototype.
