Results of ESA-GEENRAIM Test Activities Part 1: Experimental Investigation of a 1 Newton Hydrogen Peroxide Monopropellant Research Thruster

Kurzfassung

Within the frame of the European Space Agency (ESA) activity GreenRAIM, an extensive test campaign involving various monopropellants was undertaken. The primary objective of this endeavor was to develop a comprehensive, generic model for monopropellant thrusters within the simulation software ecosim Pro/ESPSS. In this context, an additively manufactured 1 Newton monopropellant thruster has been designed and tested. The detailed design of the thruster and the experimental setup are presented. The test campaign was conducted with 98 wt.% hydrogen peroxide as propellant and a commercially available Pt/Al2O3 catalyst
