Experimental investigation of surface roughness effect on a free-flight sphere in a Ludwieg tube

Seong-Hyeon Park

Understanding the aerodynamic coefficients of meteoroid fragments, deorbiting space debris, or launch vehicle stages through atmospheric reentry is essential for ground risk assessments. In high enthalpy flow, surface roughness is a crucial factor affectin ...

Uncooperative Rendezvous in Space: Design of an Electronic Architecture for High Performance Avionic with Multi Sensor Input and Intensive Data Rate.

Michaël Yannick Juillard

Active Debris Removal missions consist of sending a satellite in space and removing one or more debris from their current orbit. A key challenge is to obtain information about the uncooperative target. By gathering the velocity, position, and rotation of t ...

Breakdown of Reye's theory in nanoscale wear

Jean-François Molinari, Antonio Joaquin Garcia Suarez, Tobias Brink

Building on an analogy to ductile fracture mechanics, we quantify the size of debris particles created during adhesive wear. Earlier work suggested a linear relation between tangential work and wear debris volume, assuming that the debris size is proportio ...

Micromechanical Origins of Adhesive Wear Mechanisms: From Asperity Smoothing to Debris Creation

Jean-François Molinari, Ramin Aghababaei, Derek Warner

The adhesive wear process consists of several physical phenomena including plasticity and fracture which occur at different length and time scales. Despite the critical importance of the adhesive wear process in all engineering applications, it is still de ...

DEVELOPING A RELIABLE CAPTURE SYSTEM FOR CLEANSPACE ONE

Pierre-Alain Mäusli, Muriel Richard, Camille Sébastien Pirat, Régis Voillat, Timothée Robert Sophus Frei, Xavier Collaud, Bastien Gorret, Michel Lauria

The objectives of the CleanSpace One mission are to raise the awareness of the orbital debris problem, develop and test technologies for non-cooperative rendezvous and as a demonstration, de-orbit the SwissCube satellite. Within this project and over the l ...
