Low cost high thrust propulsion for European strategic space launchers – technologies maturation including ground tests

< Back

Open Call Reference: HORIZON-CL4-2021-SPACE-01-22

The propulsion systems represent a significant part of launch system costs. It is necessary to mature new or optimised low cost effective, high performance and green propulsion concepts, technologies and propellants for high thrust engines

– Low cost propulsion
– Throttability
– Reduced number of parts with extensive application of Additive manufacturing, or new composite technologies

– Maintenance/overhaul

– Associated fluidics

– Contribution to the overarching objective of launch cost/price reduction by 50% by 2030
– Innovation acceleration of enabling technologies
– Identification of mature technologies at TRL 3-4 for cost-reduction possibilities in the current European launchers
– Matured technologies up to TRL 5-6 by 2023/24, prototyping and on ground tests at engine subsystem and system level by 2025/26
– Cost reduction investigation and demonstration
