  1. 1. Conceptual Design of an Ekranoplan UAV

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sheng-An Yu; [2022]
    Nyckelord :Ekranoplan; Unmanned ground effect vehicle UGEV ; vertical take-off and landing VTOL ; aircraft design; Ekranoplan; Obemannad markeffektfarkost UGEV ; Vertikal Start och Landning VTOL ; Flygplansdesign;

    Sammanfattning : Unmanned aerial system (UAS) has developed into an important platform of high-altitude photography, which can be applied in animal studies, pollution forensics and geographic monitoring. This thesis work aims to design a unmanned ground effect vehicle (UGEV) in order to provide a much better and flexible solution to future applications. LÄS MER

  3. 2. Design and development of a submersible UAV

    Master-uppsats, KTH/Flygdynamik

    Författare :Adam Olsson; [2021]
    Nyckelord :UAV; Drone; Submersible; VTOL;

    Sammanfattning : Using autonomous underwater vehicles is a popular method of collecting samplesand conducting surveys, but the transportation of this information is not always easy.The underwater vehicle might be unable to transmit the information wirelessly, andsamples may be required to be transported a long distance.

  4. 3. Conceptual Design of a Small­ Size Unmanned Air Vehicle : Part A: Aerodynamic Performance and Structural Design

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Adrian Pellnäs; Johanna Sandeberg; [2021]
    Nyckelord :;

    Sammanfattning : In this report, the conceptual design of an unmanned aerial vehicle (UAV) and aerodynamic analysis is treated. The project was split into two groups, one group would do the aerodynamic analysis, and the other group would do the performance analysis. LÄS MER

  5. 4. Conceptual Design of a Small Size Unmanned Air Vehicle : Part B: Flight Performance and Flight Mechanics

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Arastoo Bayati; Peter Reinders; [2021]
    Nyckelord :UAV; VTOL; Flight mechanics;

    Sammanfattning : This report summarizes the task of conceptually designing an UAV suited for agricultural observation of Swedish farmland. The design of the UAV was divided into two parts. This report focuses on the flight mechanics, performance analysis, and cost analysis of the UAV, whereas the other part centers around the aerodynamic performance. LÄS MER

  7. 5. Robust control system development forVTOL-to-fixed wing flight transition withthe EcoSoar UAV : A masters thesis in Automatic Control

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robert Hedman; [2020]
    Nyckelord :drone; UAV; thesis; automatic; control; VTOL;

    Sammanfattning : A non switching, non linear, quaternion based attitude P2 controller, together with a sensitivitynormalizing function for the control surfaces has been simulated and implemented on a flying fixedwing with non vectored engines. In simulations the controller worked well in all flight modes,hovering, transition and flying, and also rejected a simple wind disturbance in all modes. LÄS MER
