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. Study of tip clearance flows

   Master-uppsats, KTH/Flygdynamik

   Författare :Camille Fournis; [2018]
   Nyckelord :turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

   Sammanfattning : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. LÄS MER
