  1. 1. Evaluation of solar powered systems in small scale UAV designs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lukas Girlevicius; [2022]
    Keywords : ;

    Abstract : Unmanned Aerial Vehicles (UAV) also know as drones are becoming increasingly present in modern societies. Despite their versatility and success in many areas, small scale UAVs which are nearly always battery powered and therefore have limited flight endurance. READ MORE

  3. 2. Risk of fragment hit on aircraft after releasing a bomb

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hedberg Joakim; [2022]
    Keywords : Flightmechanics; probability; aerodynamics; Flygmekanik; sannolikhet; aerodynamik;

    Abstract : An aircraft is exposed for a certain risk during warhead deployment. If the distance is too short between the aircraftand warhead during burst, fragments may hit the aircraft with fatal consequences. The warhead consists not onlyof fragments created during burst but also parts to attach it to the aircraft such as mounting plates and fasteningloops. READ MORE

  4. 3. Experimental Investigation of the Aerodynamics of a Sailing Cargo Vessel with Four Rigid Wingsails under Unsteady Sailing Conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Antonia Hillenbrand; [2022]
    Keywords : Experimental Aerodynamics; Pressure measurements; Sailing; Scale model testing; Trimming; Sea trial; Experimentell aerodynamik; Tryckmätning; Segling; Testning av skalamodeller; Trimning; Sjöprovning;

    Abstract : Wind propulsion is a traditional way to propel ships over the oceans. In the recent development towards more sustainable shipping, sailing is considered in the industry again with high momentum. For a modern merchant ship, the aerodynamic forces generated on the particular rigging are unusual. READ MORE

  5. 4. Development of a Low Speed Wind Tunnel Test Campaign

    University essay from KTH/Flygdynamik

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE
