  1. 1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :David Fredouelle; [2023]
    Nyckelord :Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Sammanfattning : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. LÄS MER

  3. 2. Record of the end-Triassic mass extinction in shallow marine carbonates: the Lorüns section (Austria)

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Linus Brakebusch; [2022]
    Nyckelord :sedimentology; geochemistry; ooids; oolites; oncoids; oncolites; Triassic; Jurassic; Rhaetian; Hettangian; ocean acidification; Earth and Environmental Sciences;

    Sammanfattning : The end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea. LÄS MER
