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.

Unmanned Aerial System design competition
Malinowski, Matěj ; Navrátil, Jan (referee) ; Pejchar, Jan (advisor)
Bakalářská práce se zabývá návrhem malého bezpilotního letounu určeného pro soutěž Air Cargo Challenge 2015. Práce je uspořádána dle postupu vývojových prací. Na prvotní koncepční návrh navazuje volba vhodného tvaru letounu a jeho profiláže. Následuje výpočet letových výkonů, maximální vzletové hmotnosti a centráže letounu. Poslední část práce se zabývá konstrukcí letounu a je provedena analýza závislosti užitečného zatížení na hustotě vzduchu.

Structural optimization of 3D-printed Unmanned Aerial Vehicle
Sladký, Martin ; Šplíchal, Jan (referee) ; Löffelmann, František (advisor)
This master thesis deals with the design of the internal wing structure of 3D printed flying wing VUT 714. As a part of this work was performed a load calculation, static strenght test, comparative FEM analysis and subsequently topology optimization was performed. The outcome of this master thesis is a rational design of the wing internal structure based on the load calculation and knowledge of effect of this load on the structure.

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.

Aerodynamic Characteristics Identification of Atmospheric Airplane from Flight Measurement Results
Zikmund, Pavel ; Salga,, Jaroslav (referee) ; Jebáček, Ivo (referee) ; Daněk, Vladimír (advisor)
The thesis deals with aerodynamic characteristics identification from flight measurement. The topic is part of flight mechanic – handling qualities. The first theoretic part consists of three identification methods description: Error equation method, Output error method and Filter error method. Mathematical model of an airplane is defined and restricted to the motion with 3 degree of freedom. There is also introduced simulation of flight measurement for identification software validation. Practical part is focused on experiment preparation, execution and evaluation. The airplane VUT 700 Specto had been chosen to carry out flight tests. The airplane was modified to the new electric powered VUT 700e Specto after first measurement flights with combustion engine. Data record from on-board measurement unit was completed by telemetric data from autopilot and remote control system. Flight tests were carried out in stabilised mode of autopilot in symmetric flight. The results were confronted with analytical analysis results and DATCOM+ software parameter estimation.

Localization and Navigation of Tello Unmanned Aircraft
Panský, Michal ; Chromý, Adam (referee) ; Gábrlík, Petr (advisor)
This bachelor thesis deals with the design of a suitable solution to control the unmanned aircraft Ryze Tello for use in autonomous missions. Its content is to familiarize and test all available SDKs and all the features they offer. Introduction to the location and navigation of robots in indoor spaces. Then there is described ROS and its implementation for the problem using the available SDK with instructions for installation and launch of the practical part. At the end of the work are displayed data obtained during the unmanned aircraft flight and the structure of the communication system, a description of the problems encountered during testing and a discussion of possible extension to this solution.

Communication network for a swarm of unmanned aerial vehicles
Rajm, Jan ; Götthans, Tomáš (referee) ; Janoušek, Jiří (advisor)
This bachelor thesis deals with creation of robust communication network used within swarm of unmanned aerial vehicles and its testing. In the first part, network requirements are presented and selected communication standards capable of transmitting telemetry data are described. The second part describes the software needed for telemetry data transmission and drone control. The third part presents designed communication network for a swarm of drones. Capabilities and differences between the designed network and networks based on other network technologies are presented. Also, the creation procedure of the designed network is described. The fourth part deals with a testing and an evaluation of results.

Expansion of Skydog Aircraft Model Control System by Remote and Autonomous Control by Android Application
Boček, Michal ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The thesis aims to design and implement an Android application with ability to control the autopilot of the Skydog aircraft model using the wireless telemetry. The application shall receive data from an aircraft model gathered from various installed sensors. These data shall be then processed and corresponding instructions for autopilot shall be sent back. When collision with terrain or obstacle is detected, the application shall send instructions to autopilot to avoid such collision. RRT algorithm is used to find collision-free flight trajectory. Database of known obstacles and digital terrain model are provided to application in formats XML and GeoTIFF respectively.
