ESA high-thrust engine takes next step


NGL concepts under study - Left: main stage powered by a cryogenic liquid oxygen and hydrogen engine (staged combustion cycle), with a cryogenic reignitable engine for the upper stage. Right: first two stages powered by solid propellants, with a cryogenic reignitable engine for the upper stage.


ESA is preparing the NGL Next-Generation Launcher to meet Europe's institutional needs and safeguard its guaranteed access to space into the long term, ensuring it will continue to have effective and economic launchers at its disposal.

The work is being performed under the Agency's Future Launchers Preparatory Programme (FLPP), which is identifying and studying new launch vehicle concepts and anticipating the technologies to make them possible.

Many configurations have been screened and studied on the way to the current four, using two and three stages to orbit, different types of liquid and solid propellants and a cryogenic upper stage.
