PARAMESWARAN, ADVAIT (author)With a growing trend in the miniaturization of satellites, there was a need to develop micro-propulsion systems for these satellites. Since there was a challenge to scale-down conventional propulsion systems, new concepts needed to be developed. One such concept was the micro-resistojet thruster which used heat input to accelerate the propellant...master thesis 2023

Vissers, Casper (author)Quantifying the exergy requirement of propellant insertion into LEO can lead to insight into the feasibility of a lunar propellant-generating architecture. Spacecraft leaving from Earth can greatly reduce their lift-off mass if in-space refueling would possible. Exergy analyses quantify the available energy of a system and show where a reduction...master thesis 2023

De Smaele, Kasper (author)CubeSats suffer from low reliability and have little to no Fault Detection, Isolation and Recovery mechanisms onboard. Advanced CubeSat missions such as the Lunar Meteroid Impact Observer (LUMIO), will use more complex attitude determination and control systems, increasing the need for advanced fault detection. Traditionally this requires model...master thesis 2023

Lengkeek, Pjotr (author)High power to weight turbo-pumps enable the creation of powerful compact rocket engines capable of launching payload to space. The desire to reduce cost of payload to space requires engineers to push the limits on hardware. Cavitation in turbo-pumps is a phenomenon requiring mitigation when pushing pump rotational speeds and reducing vehicle...master thesis 2023

van Staaveren, Niels (author)In-space manufacturing (ISM) is an upcoming technology in the space industry. Unprecedented applications can be achieved by producing objects in space, as opposed to bringing objects to space that were produced on Earth. For solar arrays, this means that extremely large array sizes can be achieved, because with ISM the array size is not limited...master thesis 2022

Manafu, Marius (author)The technology of focus in this paper, the applied-field magnetoplasmadynamic (MPD) thruster (AF-MPDT), was developed in the 1960s. However, little research has been conducted for this thruster. There is still the need for an accurate model describing the thruster's functioning, its thrust and the physical phenomenons inside.<br/>This project...master thesis 2022
