  1. 1. Jet Engine Recycle Model : A Case Study to Design a General Model to be Used on Jet Engines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Felicia Dyberg; [2023]
    Keywords : Jet Engine Recycling; Recycling of Aircraft; End-of-life Engines; End-of-life Aircraft; Sustainable Recycling; Innovative Recycling; Engine Materials; Circular Economy; 3D-printing.; Jetmotoråtervinning; Återvinning av Flygplan; Uttjänta Motorer; Uttjänta Flygplan; Hållbar Återvinning; Innovativ Återvinning; Motormaterial; Cirkulär Ekonomi; 3D-Utskrift.;

    Abstract : 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. READ MORE

  3. 2. Klimateffekterna av elektrobränsle för flyg

    University essay from SLU/Dept. of Energy and Technology

    Author : Jonatan Persson; [2023]
    Keywords : Livscykelanalys LCA ; växthusgaser; klimatförändringar; Carbon Capture and Utilization CCU ; flygindustrin; utsläppsminskningar; HySkies;

    Abstract : Kan elektrobränsle vara den nyckeln som flygindustrin behöver för att bekämpa klimatförändringarna? Detta arbete handlar om att utföra en livscykelanalys av elektrobränsle för att bedöma dess effektivitet som en hållbar lösning för att minska klimatpåverkan från flygindustrin. Elektrobränsle är en variant av hållbart flygbränsle, SAF (Sustainable Aviation Fuel). READ MORE

  4. 3. Taking Flight Towards a Greener Future: Steps Airlines Can Take to Reduce Emissions

    University essay from Lunds universitet/Trafikflyghögskolan

    Abstract : 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. READ MORE

  5. 4. Methodology for analysis of vibration isolating systems

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Jonas Olsson; [2023]
    Keywords : Vibration;

    Abstract : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. READ MORE

  6. 5. Multibody modelling of the vibrations in an aircraft engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE
