Master Thesis - OUFTI-1 Master Thesis - OUFTI-1
Acknowledgments I wish to acknowledge all the people who helped me, during the whole year, to carry out this master thesis. First of all, I would like to express my gratitude to my advisor Professor Gaëtan KER- SCHEN for his precious advice and support, and for giving me the opportunity to take one's rst steps in the fascinating world of space industries. I am deeply indebted to Professor Jean-Claude GOLINVAL who opened me the doors of his laboratory and gave me his condence to use his precious material. I would like to thank Professors Jean-Claude GOLINVAL and Pierre ROCHUS, but also Daniel SIMON and Amandine DENIS for accepting to serve on the examination commitee of this master thesis. I am pleased to acknowledge all the members of the OUFTI team, who created a pleasant working atmosphere. This year will remain a wonderful experience for me that I will never forget. Last but not least, I thank my family for encouraging and supporting me, not only during this academic year, but during my entire studies. 1
Abstract OUFTI-1, standing for "Orbital Utility For Telecommunication Innovation ", is the rst nanosatellite developed by the University of Liège as well as the rst one which was ever developed in Belgium. This name, which is a typical expression from the city of Liège showing surprise or amazement, was chosen to point up the origin of the satellite. The project takes place within the framework of a long-term program called LEODIUM (which means Liège in Latin). The main goal of this program is to open a new window on scientic careers and space-related activities. OUFTI-1 will be equipped of three payloads: • A D-STAR repeater. OUFTI-1 will be the rst satellite to use this new digital amateur radio communication protocol in space. • A digitally-controlled electrical power system developed in collaboration with Thales Alenia Space ETCA. • High-eciency solar cells from Azur Space. OUFTI-1 will be launched on board the new european launcher: Vega. This present thesis focuses on the structural design and dynamic analysis of OUFTI- 1. The design part covers essentially the creation of a reliable support for the batteries in accordance with several requirements. It includes also some changes in the general conguration of the satellite. The analysis part is based on the creation of an accurate nite element modeling procedure for electronic cards. Then, this procedure is applied to each electronic card and several FE analysis are performed to ensure the structural integrity of the satellite. Finally, a random vibration analysis is presented. The goal of this analysis is to demonstrate the ability of OUFTI-1 to survive at the launch phase. 2

Abstract<br />
<strong>OUFTI</strong>-1, standing for "Orbital Utility For Telecommunication Innovation ", is the rst<br />
nanosatellite developed by the University of Liège as well as the rst one which was ever<br />
developed in Belgium. This name, which is a typical expression from the city of Liège<br />
showing surprise or amazement, was chosen to point up the origin of the satellite. The<br />
project takes place within the framework of a long-term program called LEODIUM (which<br />
means Liège in Latin). The main goal of this program is to open a new window on scientic<br />
careers and space-related activities.<br />
<strong>OUFTI</strong>-1 will be equipped of three payloads:<br />
• A D-STAR repeater. <strong>OUFTI</strong>-1 will be the rst satellite to use this new digital<br />
amateur radio communication protocol in space.<br />
• A digitally-controlled electrical power system developed in collaboration with Thales<br />

<strong>OUFTI</strong>-1 will be launched on board the new european launcher: Vega.<br />
This present thesis focuses on the structural design and dynamic analysis of <strong>OUFTI</strong>-<br />
