Unmanned aircraft powertrain characterization
 Serediuk, Vadym ; Matějů, Jiří (referee) ; Dvořák, Petr (advisor)
The aim of this bachelor thesis is to recommend the most efficient electric propulsion system from the selected ones. The beginning is devoted to research in the field of electric propulsion systems and to description of their main parameters. The theoretical part is followed by a practical one, which is divided into two series of measurements. First, the performance characteristics of various motor-propeller combinations are measured. On the basis of the received data, a comparison of propulsion systems in terms of efficiency is made, the most suitable propeller-motor combination is recommended. The last part is devoted to the measurement and visualization of the airflow velocity field behind the propeller.
