  1. 1. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  3. 2. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Emil Vejlens; Dylan De Jourday; [2022]
    Keywords : Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

    Abstract : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. READ MORE

  4. 3. Centrifugal Turbopumps - Flow Physics and Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Carl Eriksson; Hampus Henåker; [2021]
    Keywords : Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

    Abstract : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. READ MORE

  5. 4. Robust Booster Landing Guidance/Control

    University essay from KTH/Optimeringslära och systemteori

    Author : Ugurcan Çelik; [2020]
    Keywords : Booster; Rocket; Reusable; Stage; Vertical; Landing; Auto-Pilot; Guidance; Control; Navigation; Reinforcement Learning; Robust; Optimization; Optimal Control; Uncertainty Analysis; Booster; raket; återanvändbar; scen; vertikal; landning; autopilot; ledning; kontroll; navigering; förstärkningsinlärning; robust; optimering; optimal kontroll; osäkerhetsanalys;

    Abstract : The space industry and the technological developments regarding space exploration hasn’t been this popular since the first moon landing. The privatization of space exploration and the vertical landing rockets made rocket science mainstream again. READ MORE

  6. 5. Effects and safety of selected antagonistic bacteria against Escherichia coli in leafy green vegetables

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Noora Ulla Annikki Nurminen; [2017]
    Keywords : ready-to-eat salad; Antagonist; Escherichia coli; food technology; livsmedelsteknologi; Technology and Engineering;

    Abstract : We live in a busy world, where the demand of ready-to-eat (RTE) salad products has increased rapidly in a relatively short time. Despite of being an easy and fast way to add more vegetables to the daily diet, RTE salads have a serious underlying risk and the amount of vegetable-derived foodborne disease outbreaks has been increasing.
