Multicopter-typed unmanned aerial vehicles, called drones, have been attracting wide attentions for hobby, aerial photography and various industrial use. For industrial use, drones usually fly in areas with various aerodynamic disturbances and obstacles, and it is essential to control its attitude and position accurately for save operations. Flying animals, such as insects and birds, fly with flexible wing and achieves highly robust and efficient flight. In this study, inspired by unique morphology and structure of animals, we have developed high-performance flexible rotary wings for drones. Gust response of propellers are measured experimentally using 6-axis loadcell. Passive deformation under the disturbances are filmed by a high-speed camera. Through the experiments, it is found that the insect-inspired flexible propeller can suppress the unstable torque under gust by the passive wing deformation.
