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.

Airplanes powered by eletric energy
Behúl, Michal ; Hlinka, Jiří (referee) ; Bencalík, Karol (advisor)
The aim of this bachelor’s thesis is electric propulsion used in airplanes and overview of airplanes with this kind of propulsion. Thesis is divided into three main parts. First part describes electric propulsion systems, mainly descriptions of batteries. Second part describes chosen airplanes with electric propulsion in use and promising prototypes still in development. Third part is construction design of electrical propulsion system with 50 kW motor, mainly focusing on computing needs for batteries.
