  1. 1. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Luis Alfonso Penela Guerrero; [2022]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Sammanfattning : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. LÄS MER

  2. 2. Framework to set up a generic environment for applications

    Master-uppsats, Linköpings universitet/Interaktiva och kognitiva system

    Författare :Ruben Das; [2021]
    Nyckelord :containers; docker; orchestration; kubernetes; infrastructure as code; terraform; mtte;

    Sammanfattning : Infrastructure is a common word used to express the basic equipment and structures that are needed e.g.  for a country or organisation to function properly. The same concept applies in the field of computer science, without infrastructure one would have problems operating software at scale. LÄS MER

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

    Master-uppsats, 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.

  4. 4. Rapid prototyping with fiber composites - Manufacturing of an amphibious UAV

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Zlatan Ramic; [2021]
    Nyckelord :CFD; FRP; CFRP; UAV; AUAV; FEM; Solid mechanics; fibre composites; ANSYS; lightweight structures; CFD; FRP; CFRP; UAV; AUAV; FEM; hållfasthetslära; fiberkomposit; ANSYS; lättkonstruktion;

    Sammanfattning : Rapid prototyping has in the last few years gained an ever increasing central role in projects thanks to its agile benefits. Because of that, boundaries regarding what can be accomplished can be pushed and new techniques for achieving goals can be explored at a reasonable cost. LÄS MER

  5. 5. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Sara Ghika; [2021]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; Mekanisk Design; Analys och Tillverkning av Vindtunnelmodell och Stödstruktur;

    Sammanfattning : This volume covers the phases from design to manufacturing of a wind tunnel test support structure for a conceptual blended wing-body UAV designed by KTH Green Raven Project students. The innovative aircraft design demonstrates sustainability within aviation by utilizing a hybrid electric-fuel cell propulsion system. LÄS MER
