Quadcopter Flow Field Research

This paper aims to establish a complete quadcopter flying flow model and observe the flow field of lift variation, the flight flow model uses quadcopter hovering flight as the basic infrastructure, added with the standard external flow field to simulate the flow field when hovering. First, according to the literature review, the research focus on control and efficiency, and has not been studied for its flight flow field. Therefore, in order to observe easily the changes in the lift of quadcopter rotor rotation, the research use commercial product DJI F450 as the main object and each rotor blade set the same location in the analysis software-Autodesk Simulation CFD. This simulation software uses transient analysis to analyze the whole flow field and adjust the wind speed and direction, in order to analyze the impact of the quadcopter. The results of this study show when hovering flight, the horizontal wind and -30 degrees wind direction (the -30 degrees means the angle between the wind blowing from top to bottom) causes the lift differential (Dissymmetry of lift) most significant.
