  1. 1. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Simone Guietti; [2024]
    Nyckelord :Pintle injector; space propulsion; space engineering;

    Sammanfattning : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. LÄS MER

  3. 2. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Weideskog; [2024]
    Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

  4. 3. Filling the gap Within Micromobility : Prototype of a Small Efficient Foldable Electric Vehicle With Long Range

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Fredrik Lien-Oscarsson; [2023]
    Nyckelord :Micromobility; Car; Electric car; Batteries; Electric motor; Efficiency; Foldable; Long range;

    Sammanfattning : Micromobility has been on the rise lately with a vast catalogue of electric vehicles reaching the market. Electric scooters, mopeds, bikes, one-wheelers and other vehicles have become the norm in everyday life. Most of these vehicles are meant to replace smaller modes of transport such as ordinary bicycles and skateboards. LÄS MER

  5. 4. Electric Leisure Boats: Enablers and Barriers : A case study of leisure boat manufacturers

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

    Författare :FREDRIK IHRFELT; [2023]
    Nyckelord :Leisure boats; electric boats; electrification; technology management; innovation; industrial transformation; accelerators.; Fritidsbåtar; elbåtar; elektrificering; teknikledning; innovation; industriell transformation; påskyndare.;

    Sammanfattning : Combustion engines and fossil fuels have traditionally driven motor-powered leisure boats. Electrification is quickly transforming the transportation sector, but electric boats are rare. The primary drawback of the electric boat is the high production cost. LÄS MER

  7. 5. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

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

    Författare :Daniel Milenkovic; [2023]
    Nyckelord :Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Sammanfattning : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.
