Conceptual design of a hydrogen powered ultralight aircraft
Vrana, Andrej ; Zikmund, Pavel (oponent) ; Koštial, Rostislav (vedoucí práce)
This master’s thesis deals with the conceptual design of a small ultralight aircraft, that uses hydrogen as its main fuel source. The thesis describes the main problem of hydrogen utilization in the aviation industry and provides the reader with an overview of existing aircraft with this power source. The design consists of a selection of suitable powerplant components, which was made after extensive research, and of the aircraft geometry design itself. The basis of the whole powerplant is a fuel cell, which produces electric energy from hydrogen, that drives a propeller via an electric motor. The aircraft geometry design was made according to CS-LSA regulations and is largely based on statistical values of dimensions of aircraft from the same category. The conceptual design is provided with a weight and balance analysis, a flight envelope according to regulation and an analysis of basic flight performance. In the end, a conclusion was made about the feasibility of operation of such an aircraft and about the compliance with regulation.

Conceptual design of training aircraft with electric propulsion
Seman, Matúš ; Zikmund, Pavel (oponent) ; Hlinka, Jiří (vedoucí práce)
This thesis is focused on conceptual design of electric powered training aircraft, using certification guidelines CS-LSA. Designing process of geometrical and aerodynamic characteristics is primary based on statistics of certificated aircrafts in this particular category. The following calculation of performance stabilities and flight performances is based on knowledge of aerodynamic polar. The calculation of the polar is also part of this thesis. The last part of the thesis consists of construction design of the front part of fuselage and engine static structural analysis of engine mounts.
