UAV Flight Reappearance and Failure Analysis

This paper described a study for the UAV flight replay and UAV fault analysis. The flight data processing was done by MATLAB. The three-dimensional model established by AC3D was imported into FlightGear. This study achieved the flight simulation visualization and replayed the arbitrary time period data of UAV flight trajectory and attitude. This study was used for crash failure analysis in UAV dynamic test, which can improve UAV flight performance, shorten r&d period and improve development efficiency, thereby broadening UAV research perspective.
