  1. 1. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andrea Martinez Sanz; [2023]
    Nyckelord :Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

    Sammanfattning : 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. LÄS MER

  3. 2. Development of Operations Complement to the Space System Ontology

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Kiira Tiensuu; [2022]
    Nyckelord :space systems engineering; model-based systems engineering;

    Sammanfattning : Space system development is a complex process that typically involves multiple stakeholders. Traditionally, information is captured and exchanged in the form of documents. Efficient exchange of information is crucial, but often challenging with the traditional document-based approach and multitude of stakeholders. LÄS MER

  4. 3. Concurrent Engineering and Generative Design Methodologies Applied to the Design and Analysis of a Future Space Mission Using COMET

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Paloma Maestro Redondo; [2021]
    Nyckelord :Concurrent Engineering; Concurrent Design; CDF; Generative Design; SpaceMaster; Space System Engineering; Feasibility Studies;

    Sammanfattning : Concurrent Design studies have become of great importance in the space industry reducing the time and costs associated to the feasibility assessments for future space missions. This has also helped companies and space agencies to be at the forefront of this fast-developing sector. LÄS MER

  5. 4. Development Model of a Gas Pressure Regulator for Spacecraft Propulsion : Design Enhancement and Testing

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FILIPPO POZZI; MARCUS SJÖBERG; [2021]
    Nyckelord :;

    Sammanfattning : This thesis treats the testing, analysis, and continued development of a mechanical pressure regulator prototype, intended for use in spacecraft propulsion systems. Herein referred to as the Adapted Mechanical Pressure Regulator (APR), the regulator is an adaptation made by the Swedish space system developer OHB Sweden AB (OSE) of an existing patented design originally intended for use outside of the space industry.

  7. 5. Development of a Software Tool for Mid-Spatial Frequency Analysis

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Albert Eriksson; [2021]
    Nyckelord :Optics; Optical Surfaces; Surface Texture; Optical Equipment; Spatial Frequency; Power Spectral Density; OpticStudio; Luleå Technical University; OHB System AG; Optical Performance;

    Sammanfattning : The manufacturing of optical components, such as lenses or mirrors, consists of numeroussteps that are essential to the performance of the fnished optical system, such as the specifcation ofthe optical surface. For a longer period, the main focus has been in identifying and restricting thenegative effects of the low and high spatial frequency content of the surface. LÄS MER
