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. Risk computation for atmospheric re-entry

   University essay from KTH/Rymdteknik

   Author : Florian Teilhard; [2021]
   Keywords : Spacecraft Dynamics; Atmospheric re-entry; Rymdfarkosters dynamik; Atmosfäriska återinträdet;

   Abstract : In the present work, two numerical tools are under scrutiny. Both were made to study the atmospheric re-entry of a spacecraft: DEBRISK computes the trajectory and the survivability of the spacecraft as well as its fragments, and ELECTRA calculates the trajectory of the spacecraft and its fragments, as well as the associated on-ground risk of human casualty.

4. 3. Methods to operate and evaluate the performance of a cold-gas CubeSat propulsion system on a magnetically stabilised satellite

   University essay from KTH/Rymdteknik

   Author : Victor Alberto Gonzalez Marin; [2020]
   Keywords : Propulsion system; CubeSat; Performance; Operating procedure; Mission experiment; Framdrivningssystem; CubeSat; Prestanda; Driftsrutin; Driftprov;

   Abstract : Propulsion systems allow satellites to perform many functionalities in space, such as orbital station keeping, reentry control, attitude control, orbital transferring, rendezvous operation, and even more thrilling, interplanetary travel. Indeed, propulsion systems in satellites have fostered a new favourable era of space exploration and application, therefore, detailed processes to operate propulsion systems need to be developed so that space missions, carrying this valuable system, are completed successfully.

5. 4. Improvement of a Space Surveillance and Tracking Analysis tool

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Francesco Fiusco; [2018]
   Keywords : ;

   Abstract : This thesis deals with the improvement of SPOOK (SPace Objects Observation and Kalmanltering), an orbit calculation tool developed by Airbus Defence and Space GmbH. The workdescribed in this thesis aims at improving the architecture and analysis capabilities of thesoftware on dierent levels: Design and build a framework that can use SPOOK as a calculation engine and use itscapabilities to build a complete SST system for man-made objects orbiting the Earth,providing commercial services (e.
