  1. 1. Experimental study on the effect of rocket nozzle wall materials on the stability of methane

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

    Författare :Thomas L. Holmboe; [2023]
    Nyckelord :Methane; pyrolysis; catalysis; nickel; coke deposition; chemical modelling; GRI3.0; rocket nozzle; regenerative cooling;

    Sammanfattning : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.

  3. 2. Making Space Exploration Sustainable: A Quantitative Assessment of Valuable Elements for Implementation of In-Situ Utilisation of Lunar Resources

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Bella Klaus; [2022]
    Nyckelord :Sustainable Development; extra-terrestrial resources; lunar resource mining; in-situ resource utilization; moon; space exploration;

    Sammanfattning : Exploring the Solar System is an ongoing process of humanity that cannot be stopped. It requires large amounts of resources to explore space, which need to be acquired from somewhere. Resources mined on Earth cannot be diverted from vital productions on Earth as those required for energy systems transition and developing a sustainable society. LÄS MER

  4. 3. A Preliminary Framework For The Selection Of Materials & Manufacturing Processes For Lunar Surface Systems Assuming Integration To A Space Circular Economy

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Gabriel Sanchez; [2022]
    Nyckelord :Embodied Energy; Space Habitat; Re-Purposability; Material Value; Sustainability; Space Recycling; Design for Recycling; Design to Repurpose;

    Sammanfattning :  In-situ resource utilization and in-situ manufacturing are being actively pursued as ways to enhance the development of human activities in space. However, the re-purpose of space systems through processes like recycling, re-manufacturing, and re-use, has not received the attention it deserves given its potential to reduce the waste generated by human activities in space, improve the sustainability of space habitats, and reduce the environmental impact on Earth of human activities in space.

  5. 4. A simulation-based approach for systematic analysis of workflow during the construction of in-situ concrete frames

    L3-uppsats, Lunds universitet/Institutionen för bygg- och miljöteknologi

    Författare :Robert Larsson; Martin Rudberg; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The construction workflow of in-situ concrete frames in multi-storey residential buildings is highly complex and dynamic. Discrete-event simulation (DES) offers capabilities to model and analyse such complexity. LÄS MER

  7. 5. Framtida användningsområden för materialadderande tillverkning : En studie i hur materialadderande tillverkning kan användas i rymden

    Kandidat-uppsats, KTH/Industriell produktion

    Författare :Leo Ullemar Loenbom; Tobias Rogefelt; [2013]
    Nyckelord :;

    Sammanfattning : In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. LÄS MER
