Aerodynamic data model analysis and simulation of ducted fan UAV

The ducted fan UAV was simply introduced in this paper. The dynamics characteristic was also analysed. The dynamics scalar equation of mass centre motion and surround mass centre motion of aircraft were built. The lift, drag, yawing force and pitch, drift, roll moment of UAV were analyzed through FLUENT simulation software. Simulation image with good effect was got. The dynamics characteristic of ducted fan UAV was reflected well and truly. This article used a mass of analog simulation software for the test. Not only reduce investment outlay, but also save time and cost of the test. We could observe the dynamics characteristic of UAV from theory and experience through this paper. The research result can offer help for autonomous flight of ducted fan UAV.
