Multicopters are useful in a variety of fields. However, there is still a risk of loss of control due to updrafts or wind generated by the multicopter itself. Therefore, the goal of this research is to achieve robust flight against wind disturbances. As a first step, we develop an onboard airflow visualization system to visualize the airflow around a propeller in flight in order to understand aerodynamic phenomena. By conducting ground experiments using a wind generator, we show that it is possible to visualize the airflow generated around a propeller. Furthermore, it is shown that it is possible to evaluate the flow field through PIV analysis of the images taken by the onboard camera.
