Overview of the development of flying cars
Kosír, Samuel ; Zikmund, Pavel (referee) ; Daněk, Vladimír (advisor)
This bachelor’s thesis is an overview of flying cars. The first part of the thesis describes their design. This part is further split into sections about technical requirements, take-off & landing modes, pilot modes, power types, propulsion system architectures, and transition between airplane mode and vehicle mode. In the second part is closely described development of flying cars in chronological order. The third part addresses legislative problems and regulations that apply to flying cars.

Modification of RAPID 200 Aircraft for Towing
Seďa, Ondřej ; Daněk, Vladimír (referee) ; Píštěk, Antonín (advisor)
This master’s thesis deal with design modification of the RAPID 200 (Skyleader 200) airplane for towing at compliance with maximum take-off weight 450 kilogramme. A necessary construction modification, a weight analysis these adjustments and a balance verification are included. The thesis contains of power plants installation consisting from the M 132 engine and the V 541.2 propeller, a towing gear and a landing gear, a load calculation of power plants and towing gear and basic flight performance calculation too. Last but not least valuation of operation ekonomy, operation characteristics assesment and a using of the airplane for specialized duty are included.

Reentry CubeSat
Kopecký, Matěj ; Daněk, Vladimír (referee) ; Zikmund, Pavel (advisor)
This bachelor´s thesis deals with the analysis of the re-entry of the miniature CubeSat satellite from lower orbit. In the opening section, it is explained how re-entry process works, what bodies are typically used and the possibilities for protecting them from atmospheric resistance. The thesis is also focused on the mentioned group of CubeSat satellites and defines them according to general requirements. Using the knowledge learned from the opening section, a theoretical introduction to the preliminary analysis of the re-entry of the CubeSat satellite was put together, followed by a sample calculation. Here, it is explained how the CubeSat moves as it descends throughout the atmosphere and what parameters it needs to meet in order to make the re-entry.

Parachute Emergency Systems for Very Light Sport Planes
Šorf, Oldřich ; Salga, Jaroslav (referee) ; Daněk, Vladimír (referee) ; Třetina, Karel (advisor)
This PhD thesis describes parachute rescue systems for small planes and focuses on their functionality in the border areas of the flight envelope, especially at very low altitudes and low airspeeds of flight (fall). For extending the functionality of the rescue system in extreme areas of usability envelope, was founded an innovative dividable parachute slider, which works normally at high speed, but at the low airspeeds does not limit the opening time of the canopy. Structural design of this slider is the subject of a new patent application “Parachute opening speed regulation device”, filed with Industrial property Office in Prague on August 14, 2014 under number 2014-543 PV. The PhD thesis further contains computational principle of circular parachute opening and the structural design. For verification of the dividable slider functionality, a parachute model has been constructed and subjected to a series of drop tests. The main benefit of the PhD thesis is extending the usability of rescue system into its statistically most frequent use, i.e. into low altitudes and low airspeeds of flight (fall).

Legal Context of Nightime Road Accidents with Pedestrians
Daněk, Vladimír ; Bradáč, Albert (referee) ; Semela, Marek (advisor)
The thesis „Legal Context of Night-time Road Accidents with Pedestrian „deals with the interpretation of legal decisions on traffic accidents caused by the vehicle during the night and where the other participant was a pedestrian. The main aim of this thesis is to find the established limits for the assessing of blame in comparable accident situations in cases of traffic accidents of the vehicle and the pedestrian at the reduced visibility with emphasis on the assessing in relation to the circumstances of the cases from the technical and legal point of view and in relation to the health consequences. Legal interpretations of the law are defined within the theoretical part of the thesis with emphasis on the ones which appear repeatedly in the judicial decisions. Approximately 1530 judicial decisions were studied and analysed in the analytical part, of which 56 were selected, that corresponds to the requirements of this thesis. There are also 5 expert evidences provided by the Institute of Forensic Engineering of Brno University of Technology. In the above mentioned cases there were defined the limits for the assessing of accidents based on which the judicial decision was predicted in context with the defined established limits for the judicial decisions at the top of the court hierarchy.

Human factor in the aircraft operations
Dostál, Tomáš ; Raudenský, Miroslav (referee) ; Daněk, Vladimír (advisor)
This bachelor´s thesis examines air accidents which is caused by human error. From selected air accidents are pointed out mistakes, which is caused by flight crew, their continuation, increase, main causation and formation air accident. Study of human mistakes and influence phase of flight are shown in diagrams. The conclusion of the bachelor thesis includes possible solving to elimination human error and increasing air traffic safety.
