Construction parts and Elements of the of Large transport aircraft Fuselage structure
Zubaľ, Filip ; Dubnický, Lukáš (referee) ; Juračka, Jaroslav (advisor)
Fuselage design is an area of aerospace engineering that combines aerodynamics with mechanical and material engineering. Many factors affect the construction and design of the fuselage. The bachelor thesis is focused on the processing and systematic ordering of individual structural units used in large transport aircraft. It points out the diversity of individual structural nodes in the design of the aircraft. The work is divided according to sections of the fuselage, where the specific design solutions for the node are then discussed. At the end of the work, I present a comparison of the two most famous competing aircraft models of Airbus and Boeing company. I pointed out the individual combinations of structural elements. Compared data are processed using tables and schematic figures. The bachelor thesis was also translated into a form of presentation intended for educational purposes.

Aircraft lifting surface morphing
Přikrylová, Helena ; Juračka, Jaroslav (referee) ; Dubnický, Lukáš (advisor)
This bachelor’s thesis deals with the introduction of morphing wing technology, more specifically camber morphing. It describes the specific requirements in terms of different construction parts by presenting various morphing concepts. The first part is dedicated to brief description of the motivation for wing morphing, that is followed by introducing different morphing concepts that use kinematic or compliant mechanisms in order to achieve shape changes of the airfoil. The need of anisotropic skin and several ways of achieving the anisotropic behaviour are described as well as the pros and cons of the use of conventional actuators and innovative smart materials. The last chapters deal with the validation of morphing wing benefits and the demonstrations of the feasibility of the morphing concepts.

Historical development of rocket engines
Šima, Dávid ; Dubnický, Lukáš (referee) ; Petrásek, Miloslav (advisor)
This bachelor´s thesis is dealing with the historic development of rocket engines and their use on rocket carriers. The work is divided into eight parts. The first part describes the principle of operation of reactive motion and derivation of the Ciolkovskij equation. The second part describes historical development from ancient China to the period before World War II. The fourth part describes the Second World War and especially the missile development in Germany during the war. The fifth part describes mainly rocket engines use in space research of the USA, Russia, Japan, the European Space Agency, India and China. The sixth part describes rocket engines of private companies which were founded in the early 21. century. The seventh part describes aerospike rocket engines and the last part describes physical engines.

Wing design of UAV aircraft
Chabada, Martin ; Dubnický, Lukáš (referee) ; Jebáček, Ivo (advisor)
The main aim of the this diploma thesis is the wing design of the UAV aircraft, including the appropriate material choice, calculation of the wing load and also strength analysis. Other goals include the design of the location and volume of fuel tanks, as well as the design of wingspan reduction after landing.

Rejected aircraft prototypes
Moštěk, Daniel ; Bartoněk, Jaroslav (referee) ; Dubnický, Lukáš (advisor)
The bachelor thesis focuses on seven rejected prototype aircraft that took part in tendering processes in Western Bloc countries during the Cold War. The development history of each of these aircraft is summarized, their technical properties are specified, the reason of their rejection is explored, and a comparison is made between them and the preferred aircraft. An assessment of gathered information is then made resulting in the conclusion that studying these rejected prototype aircraft can lead to valuable insights.

Design of ski landing gear for skiplane with short take-off and landing
Hostinský, Vladimír ; Dubnický, Lukáš (referee) ; Katrňák, Tomáš (advisor)
The aim of this bachelor thesis is a selection of the most suitable ski landing gear for a use on a given STOL aircraft and its installation on the aircraft according to the law regulations and requirements of the aircraft manufacturer. First part is strictly teoretical and deals with existing design variants of an aircraft skis. More practical second part of this thesis starts with a market research, which creates an overview of existing options of ski landing gears suitable for use on the aircraft. Part continous with a reduction of the options and ends with a choice of the most suitable one. Final part is devoted to the problem of an installation of the landing gear to the given aircraft with consideration of existing law regulations.

Haptic feedback device design for aircraft control
Dubnický, Lukáš ; Jebáček, Ivo (referee) ; Zikmund, Pavel (advisor)
This master thesis is focused on design of control stick grip and rudder pedals extension. These components are equipped with active elements, which provide pilot with haptic feedback. The purpose of the introduced design is to allow prototype to be built into the aeroplane so that the proposed concept of haptic feedback can be tested onboard. It shall verify used technical solutions as well to allow for their application on following development stages that aim at certification of the proposed haptic feedback system to be used in general aviation aeroplanes. The designed components are the successors of prototypes used for experiments carried on flight simulator. The design process follows the requirements of legislation and outcomes of the previous experiments. This thesis follows the design process from setting of the design requirements to mechanical test of 3D printed prototypes.

The meaning and essence of aeronautical information services in civil aviation
Dubnický, Lukáš ; Janhuba, Luboš (referee) ; Chlebek, Jiří (advisor)
The aim of this thesis is to produce an integrated overview and characteristic of practices and activities which are implemented to provide aeronautical information service in Czech Republic. The main information source is the Czech aeronautical law L15 which meets ICAO Annex 15 requirements. Due to high level of standardization, a great deal of information related to aeronautical information services in the Czech Republic can be understood as generally correct for ICAO based systems of other states. Where possible theoretical information are connected with practical applications.
