  1. 1. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

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

    Författare :Eglantin Gjoni; [2023]
    Nyckelord :;

    Sammanfattning : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. LÄS MER

  3. 2. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Björn Jarfors; [2023]
    Nyckelord :Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Sammanfattning : 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

  4. 3. Design of Aero Engine Mount Structure

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Leon Jörgensen Honarchian Saki; [2023]
    Nyckelord :aero engine mount systems; integration;

    Sammanfattning : This study ventures into the intricate realm of aero engine mount systems, delving into the design and optimization of these crucial components. Our research utilizes mathematical modeling, computational algorithms, and a well-coordinated integration of Python scripting with Computer-Aided Design (CAD) tools to explore the design space of engine mounts, aiming to optimize their performance.

  5. 4. Development of protecting coatings for composites in an aero-engine

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Materialvetenskap

    Författare :Julien Mertz; [2021]
    Nyckelord :composites; coatings; aerospace; aero-engine; lightning strike; fire; erosion;

    Sammanfattning : Carbon fibre reinforced polymer (CFRP) composite materials exhibit high specificstrength and stiffness therefore they can be a lightweight alternative to metalliccomponents for the front section of an aero-engine. Despite the benefit of CFRP composite materials for aero-engine applications, there arealso new challenges due to their inherent properties compared to conventionalaerospace metallic structures, such as a lower erosion resistance, poor thermalresistance, and poor electrical conductivity.

  7. 5. Virtual characterization of composite materials for aero-engine components

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Facundo Masari; [2020]
    Nyckelord :Composite; simulation; multiscale; modelling; UD; NCF; prepreg; aerospace; engine;

    Sammanfattning : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. LÄS MER
