  1. 1. 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

  3. 2. 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

  4. 3. Functional Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Brice Metzinger; [2022]
    Keywords : ;

    Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, an orbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulation of the off-design operation of the cryogenic engine of Nyx. READ MORE

  5. 4. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Adam Bussmann; [2022]
    Keywords : Hybrid; Hybrid propulsion; Hybrid propulsion system; System specific impulse;

    Abstract : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. READ MORE

  6. 5. 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
