On the Aerodynamic Analysis and Conceptual Design of Bioinspired Multi-Flapping-Wing Drones

Many research studies have investigated the characteristics of bird flights as a source bioinspiration for design flapping-wing micro air vehicles. However, to best authors’ knowledge, no drone targeted exploitation aerodynamic benefits associated with avian group formation flight. Therefore, in this work, conceptual novel multi-flapping-wing that incorporates multiple pairs wings arranged V-shape is proposed order simultaneously increase propulsive efficiency and achieve superior performance. First, mission plan established, weight estimation conducted both 3-member 5-member configurations vehicle. Several wing shapes airfoils are considered, simulations conducted, determine optimal planform, airfoil, angle, angle attack. The simulation results reveal bioinspired can 73.8%. A stability analysis tail sizing procedure performed configurations. In addition, flapping mechanisms inspected implementation designs. Finally, completed prototypes’ models vehicles presented, their features discussed. aim provide framework drones demonstrate sizing, estimation, procedures new type This work establishes first which exploits V-formation flight observed birds performance terms payload endurance.
