1. 1. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Vikramjeet Das; [2023]
   Nyckelord :rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

   Sammanfattning : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. LÄS MER

   Sammanfattning : In the advent of Space 4.0 era with the commercialization and increased accessibility of space, a requirement analysis, trade-off options, development status and critical areas of a propulsion system for a Commercial Micro Moon Lander is carried out. LÄS MER

4. 3. Optical Analysis of the Hydrogen Cooling Film in High Pressure Combustion Chambers

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Fabian Weber; [2019]
   Nyckelord :optical; analysis; hydrogen; h2; cooling; film; high; pressure; combustion; chambers; rocket; engine; thrust; experimental; oh*; shadowgraphy; flame; emission; lox; liquid; bipropellant; cryogenic; efficiency; heat; flux;

   Sammanfattning : For performance optimisation of modern liquid cryogenic bipropellant rocket combustion chambers, one component which plays an important role in reducing the wall side heat flux, is the behaviour of the cooling film. At the Institute of Space Propulsion of the German Aerospace Center (DLR) in Lampoldshausen, hot test runs have been performed using the experimental combustion chamber BKM, to investigate the wall side heat flux which is -- among other factors -- dependent on cooling film properties.
