1. Pathway for Sustainable Aviation : Analysis of Science-Based Targets for Aviation
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)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
2. Assessment of a solid oxide fuel cell powering a full electric aircraft subsystem architecture
Master-uppsats, KTH/FlygdynamikSammanfattning : This paper presents the work from a Master thesisat Bauhaus Luftfahrt (Munich, Germany) about subsystemdesign and analysis for electric commercial aircraft, particularlythe assessment of a Solid Oxide Fuel Cell (SOFC) powering a fullelectric subsystem architecture. The different components of theSOFC system architecture are modelled and assessed with theOpenMDAO framework. LÄS MER
3. Electric Propulsion in Passenger Jet Airplanes : Requirements to realize all-electric propulsion
Master-uppsats, KTH/EnergiteknikSammanfattning : Passenger jet airplane propulsion systems are today dominated by turbo-jet engines that burn fossil fuels. The unsustainability of this is a concern both from an economic and environmental point of view. LÄS MER
4. DIMONA eko Flight
Kandidat-uppsats, KTH/Farkost och flygSammanfattning : Sammanfattning Fossila bränslen som används som drivmedel i dagens flygplan bidrar till den globala uppvärmningen via den höga halten av koldioxidutsläpp. Sedan några år tillbaka har medvetenheten kring de negativa effekterna som uppkommer av fossila bränslen ökat, och av den anledning börjar man söka efter alternativa drivmedel för bland annat flygplan.
