1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Robin Drevet; [2024]
   Keywords : space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

   Abstract : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

3. 2. 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

4. 3. 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.

5. 4. Vertical landing flight envelope definition

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jack Charles Hooper; [2020]
   Keywords : trajectory optimization; pseudospectral; optimal control; re-entry; high speed aerodynamics; high angle of attack;

   Abstract : This paper will investigate the development of a landing footprint for a re-entry vehicle. Vehicles can re-enter the atmosphere with a range of orientations, velocities and flight path angles. READ MORE

6. 5. Flight Software Development for Demise Observation Capsule

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jakub Zamouril; [2017]
   Keywords : flight software; space-qualified software; safety critical software; embedded software; software architecture; software design; communication protocol design; Demise Observation Capsule;

   Abstract : This work describes the process of the design of a flight software for a space-qualified device, outlines the development and testing of the SW, and provides a description of the final product. The flight software described in this work has been developed for the project Demise Observation Capsule (DOC). READ MORE
