Engineering Physics Annotation << Back Automatic Power Cable Supply System for a Tethered Unmanned Aerial Vehicle Vishnevsky V.M., Gorkov A.N., Akhobadze G.N. An automatic system is proposed for supplying a power cable to a high-altitude landing unmanned aerial vehicle. This system is based on the combined use of a winch with a cable stacker, a tension mechanism for the power cable, a landing platform and a centering– locking device. The features of the construction and principles of operation of each of the four main components of the proposed automatic system are given. Recommendations are given on the practical implementation of each component, taking into account the level of development of modern circuit technology and small mechanization with software control. The issues related to cable winding and unwinding under the infl uence of disturbing natural factors during the operation of an unmanned aerial vehicle, as well as the processes of managing the preparation of its takeoff and landing, are analyzed. Keywords: power cable, winch, high-rise platform, lifting mechanism, cable stacker, cable tension unit, locking device. DOI: 10.25791/infizik.3.2024.1391 Pp. 15-23.
