Aircraft safety Analysis due to bird strikes
Hrotko, Patrik ; Bartoněk, Jaroslav (referee) ; Chlebek, Jiří (advisor)
This bachelor’s thesis deals with the problems of bird strikes. It examines significant factors that contribute to the occurrence of these strikes as well as potential damage to the affected aircraft and on the flight itself. The thesis also looks at legislative documents that specify requirements for the bird strike resistance of aircraft structures. Besides this, it gives an overview of current methods that are employed to ensure biological protection of airports with the aim of reducting the risk of bird strikes and pays attention to the effectivness of these methods.

Load calculation and design of control system
Lontras, Martin ; Bartoněk, Jaroslav (referee) ; Jebáček, Ivo (advisor)
This thesis deals with the control system of two-seater aircraft corresponding to CS-23 Level 2. First load calculations of each control surface are performed using the proses described in previous CS-23 regulation. This load is calculated trought the steering mechanism to control elements in cockpit. The resulting forces on the control elements are compared with the requi-rements in CS-23. Because the steering forces meets requirements is not necessary to propose changes in steering kinematics. However, there are further suggested ways of adjusting the control in case the external load would increase during further development of the airplane. At the end, the strength calculation of entire mechanism is preformed.

Remotorization of the L60 aircraft
Sahrai, Daniel ; Bartoněk, Jaroslav (referee) ; Imriš, Pavel (advisor)
The subject of the diploma thesis is the replacement of the power unit to the Aero L-60 "Brigadýr" aircraft. The reason for such a conversion is the ending life of the original power unit, accumulating technical problems and the effort to achieve higher aircraft performance during normal operation. In the introduction, the aircraft is introduced and there are mentioned the results achieved in the selection of a suitable power unit during the previous work. Furthermore, the work briefly deals with the issue of certification and selection of a suitable method that will lead to the approval of the change and to maintain the airworthiness of the aircraft. The work also addresses the effects of reconstruction on the center of gravity of the aircraft, which are minimized by the appropriate design of the engine mount. The model of such a engine mount was created in the computer software CATIA V5 and subsequently a strength analysis of nine loading cases was performed on it. Furthermore, an analytical inspection of the engine bed tubes on the struts and a check of the strength of the bolts connecting the engine mount to the aircraft airframe were performed. At the end of this work is described the practical installation of the engine and engine mount, including other engine systems.

Survey of Competition Aircraft of Aero L-159 Alca
Bartoněk, Jaroslav ; Zikmund, Pavel (referee) ; Dofek, Ivan (advisor)
This bachelor‘s thesis deals with military training and lightweight multi-role continuation trainers which are comparable with the Aero L-159 ALCA. Here, a survey of the most important airplanes is created, of their using, technical data, historical development and mutual comparison based on their flight performances and other properties. Aero L-159 ALCA is the latest construction of training and multi-role aircraft of the company Aero Vodochody and the successor of the traning airplane L-39 Albatros.

Predictive software for Earth collision with Near Eartch Objects
Stopka, Jiří ; Daněk, Vladimír (referee) ; Bartoněk, Jaroslav (advisor)
Aim of this bachelor’s thesis is to research and discuss the basics of orbital mechanics and their application on a real problem. The application of orbital mechanics is made by creating a software for predicting Earth’s collision with Near-Earth Objects in Borland Delphi 7 development enviroment. The created software should be able to predict close approaches of Earth and Near-Earth Objects in a time scale selected by user and issue a warning in case of a dangerous close approach.

Influence of space debris on satellites design
Hláčik, Adam ; Lazar, Václav (referee) ; Bartoněk, Jaroslav (advisor)
Bakalárska práca sumarizuje problém kozmického odpadu a jeho vplyvu na konštrukciu satelitov. Hlavným cieľom práce je spojiť teoretické poznatky získané skúmaním a experimentami s ich praktickou implementáciou v konštrukčnom prístupe zvanom „design for debris“. Práca sa v teoretickej časti venuje charakteristikám kozmického odpadu. Poznatky uvedené v tejto časti musia byt zohľadnené pri návrhu misie a konštrukcie satelitu. Praktická časť práce demonštruje prístup „design for debris“ na modelovej prípadovej štúdii. Konštrukčný prístup je založený na zisteniach analýzy Micro Meteriod a Orbital Debris, ktoré opisujú interakciu častíc odpadu so satelitom počas plánovaného obdobia misie. Analýza udáva obraz o populácii odpadu na vybranej obežnej dráhe, a taktiež odhaľuje zraniteľné miesta konštrukcie. Získané dáta spolu so znalosťami problematiky umožňujú navrhnúť konštrukčné alebo orbitálne úpravy, ktoré znížia pravdepodobnosť straty misie v dôsledku kolízie s odpadom.

Design of unmanned „Loyal wingman“ aircraft
Venerová, Zora ; Dubnický, Lukáš (referee) ; Bartoněk, Jaroslav (advisor)
The aim of the thesis is to research unmanned aircraft of the Loyal Wingman category and subsequently design a concept for a custom unmanned vehicle to support light combat aircraft. For this purpose, the thesis provides a detailed analysis of existing and developing types in its first part. The second part establishes requirements derived from purpose, missions, and standards. The third part focuses on designing the configuration and the influences affecting it, defining initial dimensions supported by CAD model visualization, and conducting a weight analysis and structural balance of the aircraft.

Swedish aircraft design in the Cold War period
Zúbek, Miroslav ; Bartoněk, Jaroslav (referee) ; Dubnický, Lukáš (advisor)
Swedish aircraft design is unique due to the conditions in which it had to be created. Sweden's neutrality during the Cold war was one of the main reasons why it was created, and why it is often overlooked when talking about aircraft design despite the innovations it managed to introduce. This bachelor's thesis focuses on the gradual development of the designs of Swedish origin during the Cold War. The technical requirements adapted to the Swedish defense concept are described in chapters for individual aircraft, together with the problems and solutions that the engineers had to deal with. At the same time, the work points out some specific elements of the Swedish design. The last chapters discuss the potential direction the Swedish aircraft design may take in the near future.

Design proposal and modal analysis of fixture for CubeSat vibration tests
Pospíšil, Jakub ; Bartoněk, Jaroslav (referee) ; Lazar, Václav (advisor)
Hnutí CubeSatů se v současné době těší vzrůstající oblibě, především díky možnosti zapojení širšího okruhu institucí do vesmírného výzkumu. Tento zájem zároveň vyvolává nutnost provádět mechanické zkoušky CubeSatů dříve, než je bude možné vypustit do vesmíru. Tato závěrečná práce zpracovává problematiku mechanických zkoušek u CubeSatů a provádění jejich vibračních zkoušek. Na základě této rešerše je proveden návrh přípravku o velikosti 6U včetně modální analýzy a ověření vyrobitelnosti.
