"CRARF - Collisional - Radiative models development and validation for Aerospace Reactive Flows"

Electric propulsion systems (EP) are nowadays routinely employed to propel spacecraft in both commercial and scientific missions by means of a thrusting plasma jet.

Despite decades of research and development, the accurate determination of the main mechanisms governing an optimal  electric power-to-thrust conversion still necessitates substantial effort.

The assessment of breakthrough concepts as well as the optimization of existing technologies both require the reliable understanding of the underlying processes ruling the plasma production, confinement, and acceleration in a plasma jet.

The project addresses the development of top-notch experimental and modeling tools to enhance improvements of EP system performances with respect to mission acceptance requirements.

The objective is to adduce reliable responses to advance EP technologies considered by aerospace engineers into higher level of readiness.


Yacine Babou obtained in 2007 his Ph.D in Plasma Physics at "Université d'Orsay Paris XI". The thesis research, conducted at laboratory "Énergétique Macroscopique et Moléculaire, Combustion", have conjugated experimental and theoretical investigations of non-equilibrium plasmas to produce up-to-date data necessary for aerospace community to tackle the design of spacecraft thermal protection systems.

In the wake of the PhD, he integrated in 2008 as Senior Research Engineer the Aeronautics and Aerospace department of Von Karman Institute for Fluid Dynamics (Belgium).  His prerogatives were to lead research activities involving various plasma facilities to investigate on ground heat flux conditions encountered during an atmospheric entry. 

A substantial part of his scientific commitment is dedicated to the development of breakthrough methods to characterize plasmas flows and high-speed flows: optical emission spectroscopy, tomography, planar-induced-fluorescence...
