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

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Henrik Nilsson; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from Umeå universitet/Institutionen för fysik

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

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Hampus Falk; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from KTH/Mekanik

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

    Abstract : 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.
