Evaluating the effect of wind on drone motion is important for improving stability and controllability. In this study, we aimed to evaluate the effect of a downward jet on drone attitude control. In the experiment, a jet with a nozzle diameter of 1.6 mm and an exit velocity of 45 m/s was directed from above at a flying drone. Based on the equation of motion for rotation, the time change in angular velocity was calculated from the torque calculated from the jet's wind pressure and propeller thrust. The calculated angular velocity was roughly consistent with the measured value, demonstrating that it is possible to predict the change in angular velocity of a drone from wind strength.
