  1. 1. Conjugate Heat Transfer Analysis of HPGP Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. LÄS MER

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

    Författare :Therese Bäckström; [2023]
    Nyckelord :Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

    Sammanfattning : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. LÄS MER

  4. 3. RECOMMENDATIONS FOR A DEPENDABLE ROV SYSTEM FOR SWEDISH MARITIME RESEARCH

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :David Bernström; Erik Nyström; [2023]
    Nyckelord :;

    Sammanfattning : A Remotely Operated underwater Vehicle (ROV) faces many problems regarding dependability and most issues come during launch and recovery. The thesis looks at finding what dependability aspects shall be considered when developing a modular ROV to come up with recommendations for a system, together with a more reliable method of launching and recovering ROV’s.
