Challenges and Opportunities of Green Propellants and Electric Pump Feeding for Future European Kick Stages

Abstract This paper analyses the synergy between two innovative technologies: green propellants and electric pump feeding, for a 500 N engine thrust range. The novel approach is then compared to legacy configuration, i.e., an MMH/NTO pressure fed system. First, discussion of benefits challenges different technologies presented. Subsequently, proposed configuration relying on e-pumps investigated. After selecting hydrogen peroxide as baseline oxidiser, comparative analysis fuel candidates conducted, leading selection propane fuel. Furthermore, second part weights against standard one confronts their propulsive performance mass budget. Results show that implementation feeding can leverage selected propellant outpacing conventional solution.
