Priming Event Peak Pressures in Liquid Propulsion Systems

What is it about?

This research was performed to understand the effects of liquid propulsion system geometry and shape on pressure transient levels during initial system propellant priming event. We show that using a cavitating venturi along with a free-flowing manifold shape will significantly reduce peak priming event pressures at thruster valve locations, minimizing the potential damaging effects to the system and onboard components.
