  1. 36. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Hanna Marklund; [2019]
    Keywords : Supersonic retro propulsion; SRP; Mars; Human mission; Inflatable heat shield;

    Abstract : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. READ MORE

  3. 37. Preliminary design of a small-scale liquid-propellant rocket engine testing platform

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Erik Andersson; [2019]
    Keywords : ;

    Abstract : Propulsion system testing before mission operation is a fundamental requirement in any project. For both industrial and commercial entities within the space industry, complete system integration into a static test platform for functional and performance testing is an integral step in the system development process.

  4. 38. Thermal gas radiation modelling for CFD simulation of rocket thrust chamber

    University essay from KTH/Kraft- och värmeteknologi

    Author : Rejish Lal Johnson Samee Lal; [2019]
    Keywords : Gas radiation; thrust chamber; CFD; heat transfer; Rocflam3; methane; Gasstrålning; tryckkammare; CFD; värmeöverföring; Rocflam3; metan;

    Abstract : Methane and oxygen are a promising propellant combination in future rocket propulsion engines mainly due to its advantages like reusability and cost reduction. In order to have a comprehensive understanding of this propellant combination extensive research work is being done. READ MORE

  6. 40. Optical Analysis of the Hydrogen Cooling Film in High Pressure Combustion Chambers

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Fabian Weber; [2019]
    Keywords : 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;

    Abstract : 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.
