1. Paths forward for Sustainable Maritime Transport : A techno-economic optimization framework for next generation vessels
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Recently, the decarbonization of maritime transport has received increased attention, in order to align with the targets of the Paris Agreement. In 2023, the International Maritime Organization unveiled their revised greenhouse gas strategy with an ambitious target: net-zero emissions by 2050. LÄS MER
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
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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
3. Vibration analysis and testing of a 6U cubesat propulsion system
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Space industry has been booming in the recent times, investments have not justbeen made on satellites and launch vehicles but also on space sustainability. Spaceindustry has its users in national agencies, private commercial agencies, academia andexperimental organisations. LÄS MER
4. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. LÄS MER
5. Optimization and Additive Manufacturing for HPGP Rocket Engines
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : This thesis aims to investigate whether additive manufacturing is applicable in manufacturing the 1N thruster option that Bradford Ecaps offers. Therefore, the nozzle design is of particular interest as AM provides accessibilities to manufacturing complex structures. LÄS MER
