Evaluation of drone flight stability through the mean flow field around an isolated building

Abstract

Drones are widely used to conduct various missions in urban districts containing complex layouts of high-rise buildings. To promote safe, energy-efficient flights in urban areas, it is necessary to evaluate the influence of turbulent flow induced by these buildings on the flight stability of drones. In this study, we used a numerical platform to simulate the flight conditions of drones passing through different routes around an isolated high-rise building. The averaged flow fields predicted by large-eddy simulation were input into the platform to induce wind effects. The results showed that the flight conditions were significantly changed when the drone passed through separation flow structures caused by the building.
