Expander-cycle Technology Integrated Demonstrator

Development of the Expander-cycle Technology Integrated Demonstrator (ETID) began mid-2013. It is a major constituent of the Future Launchers Preparatory Programme (FLPP) and prepares competitive evolutions of upper stage propulsion for Ariane 6 and Vega by assembling technologies that pave the way for the next generation of cryogenic upper stage engines in Europe.
