  1. 1. 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)

    Author : Andrea Martinez Sanz; [2023]
    Keywords : 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;

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

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

    Author : FILIPPO POZZI; MARCUS SJÖBERG; [2021]
    Keywords : ;

    Abstract : 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.

  4. 3. Design, assembly and commissioning of a flexible testbench for propulsion system components

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gabriele Guerra; [2020]
    Keywords : ;

    Abstract : Since its foundation in 2011 and among other things, OHB Sweden has beenappointed to fully develop, from the design to the assembly, a yearly increasingnumber of propulsion systems, ranging from chemical propelled to fully electricalspacecraft. One of the major contributor to the cost of this process, both in termsof money and time spent, is the verication phase, a combination of processes thatsets out to demonstrate that all the applicable requirements are met and to provethat the system is capable of fullling its objective during the mission lifespan.

  5. 4. Satellite Front-End Equipment Based on Consumer Off-The-Shelf Single-Board Computers

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Nils Thorben Weber; [2018]
    Keywords : ;

    Abstract : This Master thesis project consists of the exploration and potentially the design and implementation of an Front-End Equipment (FEE) device based on the Beaglebone Black or similar single-board computers. During development and testing of a satellite system, FEE serves to adapt telemetry and telecommand data streams between a satellite and the ground- control system. READ MORE

  6. 5. The Effects of Different Policies Affecting the Composition of the District Heating in Sweden

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Emma Hammarsten; Peter Röhr; [2013-10-23]
    Keywords : ;

    Abstract : This thesis gives an insight in the Swedish district heating sector and its choice between two different ways of producing heat; either by using only heat boilers (OHB) or by combined heat and power (CHP). This choice is researched through different policy-instruments such as emission taxes and the EU ETS. READ MORE
