1. 1. Optimering av flyghastighet för flygplan

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

   Författare :Louise Larsson; [2023]
   Nyckelord :Aircraft flight speed; flight operations; speed optimization; Cost Index; ECON speed; Flyghastighet; flygverksamhet; hastighetsoptimering; kostindex; ekonomisk hastighet;

   Sammanfattning : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. LÄS MER

3. 2. Pathway for Sustainable Aviation : Analysis of Science-Based Targets for Aviation

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

   Författare :Sebastian Lindfors; [2023]
   Nyckelord :Aviation; Airline; Science-Based Targets initiative; Climate change; Sustainable transformation; Alternative fuels; Sustainable aviation fuels SAF ; Hydrogen; Electric aviation; Scenario analysis; Flygindustrin; Flygbolag; Science-Based Targets-initiativet; Klimatförändring; Hållbar transformation; Alternativa bränslen; Hållbart flygbränsle; Väte; Elektrisk flygning; Scenarioanalys 437 07-21;

   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

4. 3. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

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

   Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
   Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

   Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

5. 4. Recreating optimized airplane boarding methods using real-time Crowd Simulation

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Oscar Olsson; Tim Rundström; [2023]
   Nyckelord :;

   Sammanfattning : Flight delays are costly for both airline companies and the environment. A possible resolution to minimize delays is to facilitate the airplane’s boarding process. Studies have to be conducted in order to find the optimal boarding method. Instead of performing experiments in the real-world, a crowd simulation could possibly be utilized. LÄS MER

7. 5. Dark Patterns in the Travel Industry : A study on users’ perception of dark patterns on airline companies’ websites

   Kandidat-uppsats, Uppsala universitet/Informationssystem

   Författare :Ebba Holmberg; Sarah Manse; [2023]
   Nyckelord :Dark patterns; deceptive patterns; dark UX; user experience; user perception; Dark patterns; deceptive patterns; dark UX; användarupplevelse; användares uppfattning;

   Sammanfattning : This thesis investigates how airline companies use dark patterns on their websites and how users perceive them. Dark patterns are deceiving design strategies that take advantage of users by integrating misleading user interface features to trick users into doing things they did not mean to. LÄS MER
