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)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

2. 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)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

3. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.

4. Design, simulation, and testing of an electric propulsion cluster frame
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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

5. Preparation for a Thermal Balance Test of the MIST student satellite
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The MIST project was founded in 2014 at KTH and has been worked on by roughly 100 students since.Thermal engineering has been an important part of the project from start and a thermal model has beendeveloped to predict ight conditions. The thermal model created by previous students has to be correlatedby performing a thermal balance test. READ MORE
