  1. 1. Effect of working from home on engineers’ career prospects : How does working from home impact visibility and in turn the engineer’s career?

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :André Da Silva Maximino; María García Colón; [2022]
    Nyckelord :Working from home; Visibility; Career Promotion; Questerview; Thematic maps;

    Sammanfattning : Background: Working from home (WFH) has become a new tendency thanks to the improvement of technological communications that enable new flexible ways of working. Before 2020 and the Covid19 pandemic, some companies had already started implementing this approach. LÄS MER

  3. 2. Weight prediction of flight control subsystem

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

    Författare :Joel Lundahl; [2022]
    Nyckelord :Aeronautical engineering; aircraft; fighter jet; flight control system; FCS; weight prediction; early weight prediction; hydraulic system; control surfaces; actuator; subsystem; weight estimation; Flygteknik; flygplan; militärflygplan; stridsflygplan; styrsystem; viktprediktering; tidig viktprediktering; hydraulsystem; styrroder; styraktuatorer; aktuator; delsystem; viktuppskattning; metod;

    Sammanfattning : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. LÄS MER

  4. 3. Using Software-Defined Radio for ATN B1 : A look into CPDLC encoding and VDL Mode 2 transmission

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Tekniska fakulteten

    Författare :Vilhelm Melkstam; Anton Magnusson; [2022]
    Nyckelord :CPDLC; ATN B1; VDL Mode 2; Software-Defined Radio; Air Communication; Security;

    Sammanfattning : An essential part of European air traffic control is the Aeronautical Telecommunications Network Baseline 1 (ATN B1) specification. This paper sheds some light on Controller–Pilot Data Link Communications (CPDLC) and VHF Data Link Mode 2 (VDL Mode 2), two crucial components of ATN B1. LÄS MER

  5. 4. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Medet Kiflemariam; [2021]
    Nyckelord :Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Sammanfattning : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.

  7. 5. Integration of cryogenic tanks and fuel cells for future hydrogen-powered aircraft

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Grégoire Dannet; [2021]
    Nyckelord :hydrogen; aircraft; cryogenic tanks; fuel cells;

    Sammanfattning : Hydrogen is seen as the green fuel of the future for the aeronautical sector allowing to reduce the carbon footprint of commercial aviation. It is well established that the release of carbon emissions triggers global warming. Aviation, like many other industries, must reduce them. LÄS MER
