1. 1. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Hamish Keay; [2023]
   Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

   Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

3. 2. 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

4. 3. Decision Support for new Process Design via Discrete-event Simulation

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Jesper Nilsson; Steven Shamoun; [2019]
   Keywords : ;

   Abstract : As a result of the technical breakthrough of modern age, manufacturing organisations are put through immense pressure to continually improve their internal processes with the purpose of economic growth in order to stay competitive in the global market. Thus, making trial and error obsolete in the real world systems, in relation to calculated decision making. READ MORE

5. 4. Study of Argon Shrouding in Ingot Casting, with Focus on Improving the Operation at Scana Björneborg Steel Plant

   University essay from KTH/Materialvetenskap

   Author : Babak Ghazian Tafrishi; [2014]
   Keywords : uphill ingot casting; argon shrouding; steel; oxygen nitrogen uptake; stigande götgjutning; skyddad gjutning; stål; syre upptagning;

   Abstract : This thesis has been carried out as a development project at Scana Steel Björneborg with the purpose to study the influential parameters in argon shrouded ingot casting during the manufacturing of low-alloy steels. In the first stage, a literature study was conducted in order to investigate the theoretical background of the procedure and the importance of protecting the melt during ingot casting. READ MORE

6. 5. Fluid and Thermodynamic Underhood Simulations

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Begoña León Moya; [2013]
   Keywords : thermal model simulation vehicle components heat shields; Technology and Engineering;

   Abstract : The thermal model and simulation of vehicles components is necessary within the development phase of the vehicle production process. It is important to understand the thermal processes of high temperature components in the vehicle, such as the exhaust system. READ MORE
