UAV Downwash Airflow Test Rig

The use of drones or unmanned aerial vehicles (UAV) for crop spraying against diseases, pests, and weeds has increasingly become important in recent years. To measure the downwash airflow pattern generated by the rotor propeller of an UAV, a downwash airflow test rig was designed and developed. This UAV downwash airflow test rig is a prototype and unique in that it can be used to collect the downwash airflow of UAV sprayers at different hover heights and payload weights. The designed test rig is useful for investigating the parameters and distribution laws of downwash airflow velocity of UAV sprayers in outdoor conditions.
