Small Unmanned Aerial Vehicle for vegetation monitoring
Trojánek, Tomáš ; Pejchar, Jan (referee) ; Dvořák, Petr (advisor)
The aim of this thesis was to select the most appropriate platforms for the fulfillment of required flight mission. The first part reviews available unmanned vehicles suitable for vegetation monitoring and includes both commercially available and self-made types. There are presented basic parameters, recommended equipment and tested configuration of each platform. The second part includes graphical comparison of all models in different categories and the most suitable platform has been selected on its basis. The model project which is based on the selected platform is presented in the final section.

Aerodynamic design of transonic UAV glider
Kóňa, Marián ; Pejchar, Jan (referee) ; Zikmund, Pavel (advisor)
This master thesis is focused on aerodynamic design of transonic glider, which is assigned for following an airliner at cruising regime of flight. Main goal of the thesis is to determine basic geometrical design of airplane with respect to Whitcomb aera rule, mass analysis and drag polar. Weight analysis includes determining center of gravity according to longitudinal static stability margin. The drag polar of the airplane is determine for cruising regime of flight, that means the regime of following an airliner.

Aerodynamic analysis and design modifications of L 410 NG aircraft wing-fuselage junction
Derevjanik, Šimon ; Pejchar, Jan (referee) ; Popela, Robert (advisor)
This thesis deals with CFD analysis of a wing-fuselage junction on L410NG airplane. Possible modifications are proposed as well. Calibration problem solved in the introduction serves as a pathway for validation of the results and gives insight into the CFD methodology. The main part analyses the airplane's flow field and shows the details of the modelling process. Description of the computing network followed by final evaluation is presented. Next part is devoted to the creation and aerodynamic analysis of the modified geometry. Final part of the work compares both basic and modified geometry.

The requirements of the airworthiness of aircraft
Pauliny, Jan ; Pejchar, Jan (referee) ; Chlebek, Jiří (advisor)
The focus of this study is to investigate the requirements and procedures for obtaining and maintaining a certificate of airworthiness of aircraft and aeronautical products within the scope of civil aviation. The requirements investigated include the standards regarding airworthiness requirements for large airplanes, helicopters, small airplanes, engines, and propellers. The procedures for certification and continuing airworthiness throughout the design, production and operating life of an aircraft are explained.

Flying drones rescue systems
Hájek, Tomáš ; Janhuba, Luboš (referee) ; Pejchar, Jan (advisor)
This paper addresses the issue of security and integration of UAVs in air traffic operations and analyses possible risks. This work defines methodology to demonstrate airworthiness of the parachute recovery system under extreme climatic conditions. The first part of the methodology deals with the compliance performance requirements in external environment and the second part verifies performance parachute canopy. Methodology developed herein is subsequently verified by practical tests on parachute recovery system Galaxy GBS 10.
