  1. 16. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Josep Plana Riu; [2022]
    Nyckelord :;

    Sammanfattning : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. LÄS MER

  3. 17. Investigation of the wing design and endurance of an ultralight electrical aircraft

    Master-uppsats, Lunds universitet/Innovation

    Författare :Vanda Ericson; Jonathan Palmgren; [2022]
    Nyckelord :Aerodynamics; Electrical Aviation; CFD; Endurance; Drag; Technology and Engineering;

    Sammanfattning : The goal of this thesis was to explore the conversion of a propeller driven two-seater combustion airplane to an electrical airplane. Four different wing designs were considered. Two variations of Blackwing Sweden AB’s current Blackwing wing (BW), a longer wing (BW-L) and a shorter wing (BW-S), as well as a new wing with a different airfoil (GW). LÄS MER

  4. 18. The realization of a study on the current and future trends of the cost of access to space for CubeSat missions.

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Alice Phen; [2022]
    Nyckelord :CubeSat; costs; current status; future trends.;

    Sammanfattning : The increasing number of space-related applications and the development of miniaturized satellites (sometimes called CubeSats) recently became an exciting area in modern space science. Due to their diverse applications, smaller size, and low development cost. LÄS MER

  5. 19. Experimental Investigation of the Aerodynamics of a Sailing Cargo Vessel with Four Rigid Wingsails under Unsteady Sailing Conditions

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

    Författare :Antonia Hillenbrand; [2022]
    Nyckelord :Experimental Aerodynamics; Pressure measurements; Sailing; Scale model testing; Trimming; Sea trial; Experimentell aerodynamik; Tryckmätning; Segling; Testning av skalamodeller; Trimning; Sjöprovning;

    Sammanfattning : Wind propulsion is a traditional way to propel ships over the oceans. In the recent development towards more sustainable shipping, sailing is considered in the industry again with high momentum. For a modern merchant ship, the aerodynamic forces generated on the particular rigging are unusual. LÄS MER

  7. 20. Adding storage to an unmanned aerial vehicle : Without compromising the flight mechanics

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Philip Jan Grolleman; [2022]
    Nyckelord :Designing aerodynamics simulations flight mechanical engineering;

    Sammanfattning : The Swedish Sea Rescue Services (SRSS) has developed an Unmanned ArialVehicle (UAV) which they use for search and rescue missions. The SRSS wantsto upgrade this UAV to also be able to fly and drop with a package. Bydesigning according to the model of designing by HH van den Kroonenberg [2]. LÄS MER
