  1. 1. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

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

    Author : Arjun Monga; [2023]
    Keywords : coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

    Abstract : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. READ MORE

  3. 2. Wire and Arc Additive Manufacturing : Topology Optimised Vehicle Component

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Malte Petersson; [2022]
    Keywords : Wire and Arc Additive Manufacturing; Additive Manufacturing; WAAM; AM; Overhang; Cooling times; Simulation; Welding;

    Abstract : Wire and arc additive manufacturing (WAAM) is a manufacturing method using a numerical controlled motion system and a welding system to additively manufacture three dimensional components. The motion system is programmed from three dimensional computer aided design model data (3D-CAD) of the intended geometry which is then sliced in to layers and welded on additively. READ MORE

  4. 3. Low-Temperature Thermal Control System for an Environmental Chamber

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Aleksis Pauls Lindemanis; [2022]
    Keywords : Space simulator; environmental chamber; thermal control design; thermal conductivity in bolted joints; thermal simulations; Mars climate; Carbon dioxide sublimation and deposition;

    Abstract : In spite of significant reduction of cost associated with launching a spacecraft, launching deep space exploratory missions are yet to be accessible to most universities and researchers. A solution to testing scientific hypotheses and verifying technologies for space is the use of environmental chambers, also know as space simulators, - vacuum chambers, which replicate the space environment.

  5. 4. Analysis of implementing additive manufacturing for the making of casting patterns

    University essay from Lunds universitet/Industriell Produktion

    Author : Simon Håkansson; [2022]
    Keywords : 3D-printing; additive; manufacturing; polymer; plastic; wood; pattern; casting; molding; vacuum; sand; ABS; milling; turning; Technology and Engineering;

    Abstract : I den här rapporten undersöks möjligheten för att tillverka och använda gjutmodeller tillverkade genom additiv tillverkning, i folkmun kallat 3D-printing. Först görs en grundläggande analys över hur modellerna tillverkas idag och vilka krav som ställs på modellen. READ MORE

  6. 5. Investigations of p-type quantum dots in GaSb nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : In-Pyo Yeo; [2021]
    Keywords : Physics and Astronomy;

    Abstract : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. READ MORE
