  1. 1. Characterization of Lamps of IRF Solar Simulator

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Mrunmayee Sonna; [2023]
    Keywords : IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

    Abstract : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. READ MORE

  3. 2. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Therese Bäckström; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 3. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Vikramjeet Das; [2023]
    Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

  5. 4. Micromechanical Characterization of Thin Paper Materials

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Author : Linus Bengtsson; [2023]
    Keywords : Micromechanical characterization; SEM; In situ tensile testing; Paper deformation; Fiber orientation; Paper mechanics; Technology and Engineering;

    Abstract : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. READ MORE

  6. 5. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andrea Martinez Sanz; [2023]
    Keywords : Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

    Abstract : Testing of hardware to be used in space sometimes involves using vacuum chambers. The need to test hollow cathodes, used as neutralizers for some Electric Propulsion Thrusters, and low power Hall Effect Thrusters at OHB Sweden requires a vacuum chamber to be upgraded. READ MORE
