About Paper:

The design and development of bio-inspired and efficient lift-generation flapping wing vehicles (FWVs) has been gaining much attention in the field of UAV research as an alternative to rotor and blade-driven drones such as RC planes and quadrotors. Birds' flight agility, lift-generation efficiency, and ability to perform gliding flights have influenced and inspired researchers to develop novel flapping mechanisms and control algorithms to design and manufacture the FWVs. This research aims to specifically address the lift-generation efficiency aspect in developing a unique wing-folding mechanism (WFM) for a general class of bird-scale flapping wing vehicle (BFWV) with the goal of understanding the influence of wing folding and asymmetrical flapping on the aerodynamic forces and torque generation of BFWVs. Static aerodynamic forces and torque data of the wing- folding mechanism will be obtained from a 6-axis force transducer and a system-identification driven approach will be used to further develop the geometries of the WFM using parameter optimization to maximize its lift generation. A positive cycle-averaged lift generation is recorded using the WFM designed with the help of light- weight materials and parameter optimization. This allows the BFWV with such WFM to not only maintain but gain altitude during translational flights. Future work involves the optimization of linkage lengths and wing shape through simulation and experimental validation to maximize lift and thrust generation to allow for smooth translational free flight.
