  1. 1. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jonathan Envall; [2023]
    Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

  3. 2. Drones for Sea Rescue: Lab and Field Experiments on Camera Gimbal Control

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Alexander Sandström; [2023]
    Keywords : Drones; Search and Rescue; Unmanned Aerial Vehicle; UAV; gimbal; camera control; ArduPilot; Quality of Experience; QoE; Technology and Engineering;

    Abstract : The objective of this thesis has been to improve the camera controls of a fixed-wing drone to be used in maritime search-and-rescue operations by the Swedish Sea Rescue Society (SSRS). A gimbal control interface (GCI) has been implemented that displays the video feed of the drone camera while taking control inputs from a joystick that moves its view in real-time. READ MORE

  4. 3. Design of Experiment Based on Full Factorial CFD Spray Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Olle Faritzon; [2023]
    Keywords : CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

    Abstract : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. READ MORE

  5. 4. Energy flows and potential energy development strategies in RoRo ports: A study based on the Port of Trelleborg
