Design of hybrid/electric aircraft propulsion system
Dardová, Eva ; Šplíchal, Miroslav (referee) ; Opluštil, Vladimír (advisor)
The diploma thesis deals with the issue of electric and hybrid aircraft propulsion. The first part of the thesis provides a view of the issue from the technological, ecological and legislative point of view. This is followed by a section on research into electric/hybrid drive components and an overview of the component manufacturers. The research section concludes with a market survey of electric/hybrid aircraft in the experimental aircraft, CS-22, CS-LSA and CS-23 categories. This is followed by the actual design of two hybrid and one electric propulsion variants for the CS-LSA category aircraft and evaluation of operational characteristics. Finally, the engine mounting design for the electric variant is outlined.

Hybrid propulsion aircraft
Křivánek, Michal ; Šplíchal, Miroslav (referee) ; Zikmund, Pavel (advisor)
The growing efforts to reduce emissions in aviation may benefit from the use of hybrid propulsion, which is the topic of this bachelor’s thesis. The first section presents an overview of the impact of aviation on the environment as well as further motivation for the use and development of hybrid propulsion systems, due to low battery energy density, currently inadequate for purely electric aircraft use, and both complications and advantages offered by hydrogen used as fuel or in the form of fuel cells. Furthermore, it suggests a possible use of hybrid propulsion in inhabited areas and in both civil and military aviation. An overview of the most commonly used hybrid propulsion configurations follows noting the advantages and disadvantages of each of them. The next section presents an overview of several propeller-driven aircraft projects utilizing hybrid propulsion systems consisting of vertical, extremely short and standard take-off and landing vehicles, followed by a list of selected full-scale propeller-driven demonstrators utilizing hybrid propulsion systems. The final section evaluates the performance of several demonstrators in comparison to their combustion engine counterparts. The most significant advantages of hybrid propulsion aircraft are an increase in range, a substantial decrease in fuel consumption and a decrease in operation cost. However, hybrid propulsion systems also present their disadvantages too, most importantly an increase in vehicle mass and a decrease in number of passengers or amount of cargo. Lastly, the future of hybrid propulsion in aviation is outlined, considering multiple possible scenarios of development.
