Nicolas Delruelle passed his degree in aerospace engineering with flying colours at the University of Liège, Belgium, in 1987. He was soon recruited by the FN Moteur company, a subsidiary of Snecma, and was seconded to the Société Européenne de Propulsion (SEP) in Vernon, France, where he worked on testing the cryogenic engines for the third stages of the Ariane rockets. Subsequently he developed and carried out simulations for the new Vulcain cryogenic engine, for use on the Ariane 5 rockets.
