Birds with flexible feathers achieve stable flight under unpredictable disturbances. In this study, aiming at enhancing the robustness of the drones, the effect of the deflection of flexible feather models attached to the kiteplane on the robustness of the wing in disturbances is investigated experimentally. The bird-inspired kiteplane with flexible feather models on upper wing inspired by covert of bird wing is fabricated. As disturbances, the Kármán vortex street was generated by blower and cylinder at the upstream of the bird-inspired kiteplane. We measured the fluctuation of pitch angle of bird-inspired kiteplane in disturbances by using motion capture system. As a result, it is found that fluctuation of pitch angle in disturbances can be reduced by mounting flexible feather models near the leading edge. The results point out that the kiteplane can be stabilized by attaching the appropriately designed flexible feathers.
