Abstract
The shape of thin film for flapping rotor wing has a significant impact on aerodynamics. To increase lift, we designed 7 different flexible film wings. Then we compared the aerodynamic force of thin film in accordance with the same aspect ratio of different shapes and the same shape of different aspect ratio. The conclusions suitable for the thin film design guide are obtained. The aspect ratio of thin film for flapping rotor wing is inversely proportional to the aerodynamic force. At the same aspect ratio, the film wing designed by bionic is superior to other shapes. With the aspect ratio increases, the thrust of the film wing designed by bionic decreases faster than the lift.
