Experimental Study of the Flapping Amplitude Effect and Flexible Shell on the MAV Aerodynamic Performance Hovering Flight

Flapping wings are a type of aerovehicles which generate the required aerodynamic forces for own flight with the utilization of flexible wings and a mechanism supplying flapping motion. The oscillating motion of the wings is the main source of generating aerodynamic forces in birds including translational and rotational motions with two or more DOFs. Thereby, the generated wake flow creares the thrust force. In recent decades, flapping wings among other types of the aerovehicles have attracted attention due to their high maneuvering ability, high thrust efficiency and the minimal rate of energy consumption.
