AI Technical Summary

Technical Problem

Existing technologies cannot provide reliable and accurate results for atmospheric three-dimensional wind measurement compensation and correction for real UAVs, especially since interference from UAV rotor rotation cannot be accurately corrected.

Method used

By constructing a numerical simulation model for UAV wind speed measurement, the flow field under the flight envelope of the UAV in different environments is simulated, the influence of rotor flow on the anemometer is separated, and the rotor rotation flow disturbance is estimated by computational fluid dynamics and regression fitting methods. The UAV motion and attitude compensation algorithm is then used for correction.

Benefits of technology

It achieves accurate compensation and correction of UAV rotor rotation under different environments and flight attitudes, improves the accuracy and reliability of three-dimensional wind speed measurement, reduces costs, and is applicable to a variety of UAV platforms.
