Abstract

Abstract

In order to investigate the aerodynamic performance of the tethered unmanned aerial vehicle (UAV) and the deformation of the tether, the dynamic response analysis of the tethered UAV was conducted. A tethered UAV model was developed, and numerical simulations were performed using using a fluid-structure interaction (FSI) analysis method, standard k-ε turbulence model, and slip-grid technology. The dynamic performance of the tethered UAV system under crosswinds at different wind speeds was investigated. The results shows that the vortex strength increases significantly with crosswind speed, particularly on the windward side. The tether deformed under the combined effect of wind and its gravity, and the maximum deformation occurs at a specific location and varies with wind speed. The maximum deformation was 448 mm, and the overall average deformation was 145 mm in 10 s. It can be used as a reference for the design and utilization conditions of tethered UAVs.
