Offer Description
The internship will be carried out at the LHCEP in Villeurbanne. LHCEP is a joint CNRS/Université Claude Bernard Lyon 1 unit under industrial supervision (CNES, ArianeGroup), whose aim is to design and develop new polyazo compounds for propulsion. The trainee will be part of the LHCEP team, on which he/she will be able to rely. The unit has modern synthesis laboratories (La Doua site, Bâtiment Raulin, 5th floor) with all the equipment needed to study these new compounds (DSC, calorimetric bomb, shock and friction sensitivity tests), as well as modeling workstations. Its core competence lies in the chemistry of nitrogen-rich polyazo derivatives. The topic will therefore provide training in organic chemistry - here applied to the energy field.
Today, there is a strong need for research to improve propellant performance. It is crucial to be able to offer systems with a better on-board payload/total weight ratio, and therefore better operating and commercial costs.
The aim of the present project is to design and develop new polyazo compounds for propulsion, called High Energy Density Materials (HEDM), which could lead to specific impulse gains of over 30%. The key to this gain would be the energy release mechanism, which would no longer proceed from oxidative combustion, but would be directly linked to the very high decomposition enthalpy of these compounds.
HEDMs are thus breakthrough-ergols for space propulsion, which makes them high priority targets at CNES (vecteur d'innovation prioritaire, VIP).
The energy release mechanism has the additional advantage of contributing to reducing the release of environmental hazards as these "green" propellants would not require a stoichiometric oxidant and therefore would avoid the production of toxic species from the latter.
In particular, the laboratory is interested in the synthesis of extended hydrazine analogues (triazanes, tetrazanes, pentazanes, etc.).
To that end, it is important to continue exploring the construction of multiple N-N linkers, in particular by light-based or catalytic methods, so as to be able to store more energy in polyazo derivatives, and apply these methods to the assembly of the actual HEDMs. This requires to investigate the chemistry of highly nitrogenated molecules, which is a field that is very poorly understood when compared to carbon chemistry, and apply the findings to the preparation of HEDMs.
