  1. 1. DRONAR: Obstacle echolocation using ego-noise

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Henrik Nilsson; [2023]
    Nyckelord :Drone; Autonomous systems; Obstacle avoidance; Sound; Noise; Planning; SONAR; Ego-noise; Multi-rotor aerial vehicle; Unmanned areal vehicle; Drönare; Autonoma system; Hinderundvikning; Ljud; Oljud; Planering; SONAR; Egenljud; Multirotorfordon; Obemannat luftfordon;

    Sammanfattning : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. LÄS MER

  3. 2. Localization of Combat Aircraft at High Altitude using Visual Odometry

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jenny Nilsson Boij; [2022]
    Nyckelord :Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Sammanfattning : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. LÄS MER

  4. 3. Design, Modelling and Control of a Space UAV for Mars Exploration

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Akash Patel; [2021]
    Nyckelord :;

    Sammanfattning : Mars : The red planet has been on top in the priority list of interplanetary exploration of the solar system. The Mars exploration landers and rovers have laid the foundation of our understanding of the planet atmosphere and terrain. LÄS MER

  5. 4. Airborne Aircraft Detection for Multi-rotor Drones Feasibility Study of Robust Real-Time Long Distance Object Detection

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Hampus Falk; [2021]
    Nyckelord :;

    Sammanfattning : A drone is a light unmanned aerial vehicle capable of precise and agile movement. As these traits and the usability of drones are recognized in more domains, the necessity to ensure a safe airspace increases. LÄS MER

  7. 5. Lifting body design and CFD analysis of a novel long range pentacopter, the TILT LR drone

    Master-uppsats, KTH/Mekanik

    Författare :Daniel Cagatay; Haoqian Yuan; [2016]
    Nyckelord :Lifting body; CFD; Mesh; Multi-rotor; Drone; Aerodynamic; Simulation;

    Sammanfattning : In the thesis, a lifting body has been designed aiming to generate lift force for the pentacopter, called TILT LR (Long Range), at higher velocities during flights to improve the aerodynamic performances. The configuration, which is used as the skeleton of the long range drone for up to 75 kilometers flights, is based upon a tilting system allowing the rotors to rotate around their own axis in both pitch and roll angles.
