    Sammanfattning : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. LÄS MER

  5. 49. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Sophia Fisher; Michael Åkerström; [2023]
    Nyckelord :Hybrid propulsion; mixed turbofan; parallel configuration; performance;

    Sammanfattning : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. LÄS MER

  7. 50. Utilizing wood ash to stimulate algal growth in mine waters from northern Sweden

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik
