1. 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 teknikSammanfattning : 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
2. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines
Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskapSammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER
3. Jet Engine Recycle Model : A Case Study to Design a General Model to be Used on Jet Engines
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The focus on sustainability development together with the growing market of end-of-life jet engines is a reason for performing research on how to improve the recycling of jet engines. The reuse and recycling of the jet engines contributes to decreasing the need for new extracted material and processing and manufacturing new parts. LÄS MER
4. Taking Flight Towards a Greener Future: Steps Airlines Can Take to Reduce Emissions
Kandidat-uppsats, Lunds universitet/TrafikflyghögskolanSammanfattning : Background: For decades, aviation has been an important part of society and with its growth comes the increased environmental impact and the challenge to reduce this adversary effect and move towards sustainability. Objective: Find out how airlines can reduce their emissions and become more sustainable. LÄS MER
5. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER
