    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

  3. 2. Mission Design Considerations of the Propulsion System Demonstration as part of the Hugin Space Exploration Technology Satellite Mission

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Barkarmo Romil; [2022]
    Keywords : Electric propulsion system; Field Emission Electric Propulsion; Ion propulsion orbital maneuvers;

    Abstract : Beyond Atlas is a Swedish private company with the goal of exploring the solar system with cheap and reliable spacecraft. Part of their maiden mission, Hugin, aims to demonstrate navigation, propulsion, and communication technology on a 3U CubeSat. READ MORE

  4. 3. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Celeste Holm; Ida Ygland; [2022]
    Keywords : the sunshade project; geoengineering; solar sailing; attitude control; ion thrusters;

    Abstract : The purpose of the study is to evaluate the possibility of using gridded ion thrusters as a means of attitude control for a solar sail as a part of the sunshade project, which aims to place 10^8 solar sail sunshade spacecraft, each with an area of about 10 000 m^2, at the Sun-Earth Lagrangian point L1 in order to reduce Earth's global temperature. Two types of solar sail sunshade spacecraft were studied. READ MORE

  5. 4. Design, simulation, and testing of an electric propulsion cluster frame

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

    Author : Jeremy Bek; [2021]
    Keywords : Electric propulsion; gridded ion thruster; cluster; frame; thermal modelling; mechanical modelling; lumped-parameter model.; Elektrisk framdrivning; jonmotor; kluster; ram; termisk modellering; mekanisk modellering; klumpelementmodell.;

    Abstract : In general, electric propulsion offers very high efficiency but relatively low thrust. To remedy this, several ion engines can be assembled in a clustered configuration and operated in parallel. This requires the careful design of a frame to accommodate the individual propulsion systems. READ MORE

  6. 5. Experimental Verification of BP-HiPIMS Thrusters

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

    Author : David Mainwaring; [2020]
