  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
