The CALLISTO vehicle is a flight demonstrator for future reusable launcher stages. The program involves three countries and their space organizations: CNES for France, DLR for Germany and JAXA for Japan. The first tests will be conducted in 2024 from the CSG, Europe's Spaceport for commercial launches. The challenge is to develop, all along the project, the skills of the partners. This knowhow includes Products and Vehicle design, Ground Segment set up, and post-flight operations for Vehicle… Show more The CALLISTO vehicle is a flight demonstrator for future reusable launcher stages.

The department provides technical support to all CNES' projects as well as prepare the futur through ambitious R&T programs. We also develop numerical softwares. The main topics we are working on are : green monopropellant, electric propulsion (from a few watts to several kilowatts), pyrotechnics components, softwares modelling the re-entry of deorbited satellites into the atmosphere.

Once delivered, I followed the AIT activities at satellite level and took care of the anomalies. At the end of the project, I followed propulsion activities in the Kourou Space Center, in French Guiana, as well as the in-orbit commissioning phase. All this was performed under the supervision of the satellite manager and the system manager (and the Head of the project of course). Show less

Heating of droplets impacting onto a heated wall. Experimental internship using Laser Induced Fluorescence to determine the delta temperature of droplets impacting a heated wall and its evolution with wall temperature, droplets' size and incidence angle. Two papers published following this internship (one in a conference, one in the "International journal of heat and mass transfer")

Numerical simulations internship. The aim of my work was to test a 2D hypervelocity impact code in particular in terms of thermo-dynamical behavior of the impacted materials. In a nutshell : if the impact is giving so much energy to the materials that the fusion point is reached, what is the best way to deal with this new phase ?
