History of Civil Aviation 1970-2000
Sehnálková, Radka ; Bencalík, Karol (referee) ; Chlebek, Jiří (advisor)
The main subject of this bachelor’s thesis is concise and clear history of civil aviation between year 1970 and 2000. This era is typical with outset of large transport aircraft, which are intended for long distances and big number of passengers, but attention is also paid to aircraft, which are not for transport of so many passengers. Thesis is focus on concise description of individual aircraft, divided by its types of propulsions and producer.

Testing of aircraft hydraulic systems
Suk, Filip ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
My bachelor thesis “Testing of aircraft hydraulic systems“ discusses the problems of testing particular components and complete hydraulic systems. In the first part of my work, there are specified all regulation requirements that are to be fulfilled by hydraulic systems and test conditions for testing of flight control systems. The next parts deal with the way of testing particular hydraulic elements and hydraulic liquids. The last part of my bachelor thesis is dedicated to the testing's principle of hydraulic system of landing gear including a concept for instrumentation.

Proposal of electro-hydraulic system of main landing gear actuatuon for small training aeroplane
Skřivánek, Jan ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
This thesis studies the design of an electro-hydraulic landing gear and brakes control system of a trainer aeroplane. In the first part there is a basic draft of the landing gear kinematics and its loads during gear retraction, flight and landing. Braking conditions are also analysed. The thesis then focuses on the design of hydraulic circuits and their control. Simulations for studying the dynamic characteristics of the braking proportional valve and the course of plane braking were created in Simulink. There is also a brief section about reliability of the proposed system.

Measurement of parameters of the aircraft hydraulic systems
Bareš, Josef ; Třetina, Karel (referee) ; Bencalík, Karol (advisor)
This thesis summarizes current knowledge of the parameters of hydraulic systems of aircraft. Attention is paid in particular to the continuity of information and the introduction of the reader to the parameters of hydraulic systems issue and the procedures for their measurement. In the introduction the thesis deals with the properties of hydraulic fluids and their influence on the operation of hydraulic systems. Subsequently methods and instruments that are used for laboratory measurement of the parameters of hydraulic fluid are described. Furthermore, the thesis moves on to the topic of hydraulic systems for aircraft, individual hydraulic devices and fluids that are used in the air and for general operation of hydraulic systems. At the end of the thesis a balance sheet is prepared over the selection of suitable laboratory equipment for the measurement of hydraulic fluid parameters.

Aircraft de-icing systems
Smékal, Aleš ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
The bachelor´s thesis is familiarization of me with icing on aircrafts. It includes the distribution systems for anti-icing and de-icing, energy intensity and efficiency are also included. It contains icing situations, which are very dangerous for aircrafts. Thesis shows possibilities, how to prevent ice formation, detect icing and keep pilot informed. And finally remove ice.

Ecological problems of air transport
Kácal, Jan ; Bencalík, Karol (referee) ; Kaddour, Mirvat (advisor)
This bachelor’s thesis discusses the impact of air traffic on environment. The combustion of fuels causes creation of huge amount of harmful substances that are released to the upper atmosphere, where they influence the atmospheric reactions. Apart from fuels combustion, the conditions necessary for realization of air traffic, or the situations resulting from it, such as aircraft maintenance, noise, emergencies, etc., have negative impact on not only environment, but also health and comfort of people as well as flora and fauna, exposed to these conditions. Besides air traffic impacts on environment mentioned here above, this paper also describes the possibilities of their reduction and companies dealing with them.
