N2 - Dunng the start-up of the propulsion system of a satellite or spacecraft, the opening of the tank isolation valve will cause the propellant to flow into an evacuated feedhine and slam against a closed valve, inducing severe pressure peaks. An experimental campaign is pcrforrncd at DLR I.ampoldshausen to better investigate this filling process. Tests run iith saturated and dcarcated fluids clearly show the influence of the pressurizing gas on the water hammer pressure profile. To gain further insight of this aspect, a quartz pipe is installed at the dead-end and high speed imaging has been performed.
