  3. 2. Exploring Drivers and Barriers of Self-Assessment Systems for Fuel Efficiency in Aviation : A Case Study at a Scandinavian Airline

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Alexander Aronsson; David Rolstad; [2023]
    Nyckelord :Fuel Efficiency; Aviation; Self-Assessment Systems; UTAUT.; Bränsleeffektivitet; flygindustrin; själv-bedömande system; UTAUT.;

    Sammanfattning : The pollution of the aviation industry is often identified as a main contributor toward climate change, justified by the immense amounts of greenhouse gasses emitted during a flight. Therefore, it is inevitable that the aviation industry acts toward decreasing emissions of flights for mitigation of the climate crisis. LÄS MER

  4. 3. Direct Remote Id based UAS Collision Avoidance System

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

    Författare :Max Bergström; [2022]
    Nyckelord :UAS; UAV; Drones; DRI; Direct Remote Id; UAS; UAV; Drönare; DRI;

    Sammanfattning : The drone industry is growing and the need for increased autonomy will be required if large fleetof drones will be able to fly without a single pilot per drone. A useful part of automating the flighten-route can be achieved with the upcoming standard of Direct Remote Id (DRI), which signalspositional data for drones and can be used as the perceptive part in a collision avoidance systembetween drones with the advantage of limited weight penalties and minimal financial cost.

  5. 4. Turbofan Engine Modeling - For The Fighter Aircraft of The Future

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aria Tahmasebi; [2022]
    Nyckelord :Turbofan; Engine; Turbofan engine; Gas turbine; Engine model; Engine modeling; Simulink; Simulink engine; Fighter aircraft; SAAB; Engine performance; Engine optimization;

    Sammanfattning : The demand for turbofan engine performance development is high in the military industry. However, to develop the engine, it is necessary to predict its performance, and engine testing is both time-consuming and costly. Therefore, simulation is an effective approach to predicting the engine’s performance. LÄS MER
