    Nyckelord :Carbon Neutral; Business aviation; Sustainable Aviation; Sustainable Strategy; Sustainable Aviation Fuel; Hydrogen; Electric; Switzerland; Technology-Push; DemandPull.; Koldioxidneutralt; affärsflyg; hållbart flyg; hållbar strategi; hållbart flygbränsle; vätgas; elflyg; Schweiz; Technology-Push; Demand-Pull;

    Sammanfattning : This thesis emerged from a question that had been repeating itself in my head for a long period of time: If myself and the rest of the world face the fact that we are likely to keep flying for years to come for reasons somehow considered valid, how can we at the same time still contribute efficiently to achieving a more sustainable future of aviation? Based on this dilemma and focusing on the factor of impact, an actor with the power of creating a larger impact than a single individual was firstly identified. This actor also provides the perspective used in this thesis. LÄS MER

    Sammanfattning : Under de senaste Ã¥ren har flygets klimatpÃ¥verkan blivit alltmer uppmärksammad för att den, precis som annan klimatpÃ¥verkan, behöver minska. Samtidigt väntas flygresandet öka de kommande Ã¥ren och flyget är en viktig faktor för ekonomisk tillväxt i världen. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Jonathan Envall; [2023]
    Nyckelord :PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Sammanfattning : 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.

    Sammanfattning : In order for the aviation industry to meet the targets of the Paris agreement and reach net-zero by 2050, significant amounts of greenhouse-gas emissions are to be reduced. However, as the industry is essentially dependent on conventional jet fuel, it becomes necessary for alternative technologies to develop and phase out fossil-based fuels. LÄS MER

  7. 5. 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
