Liquid rocket propellant feedline dynamicsAn analytical and experimental study of liquid rocket propellant feedline dynamics has been performed. The analytical model, which includes the effects of turbulent flow, distributed and local compliances, bellows, side branches, and structural mounting stiffness, was verified by an experimental program. Water was used as the internal fluid and the dynamic perturbations in pressure and flow were created by a piston pulser. Measurements were made to determine the pressure perturbation amplitude and phase at the line terminal due to a sinusoidal pulser excitation. The frequency response of the various line configurations tested were compared with the computed theoretical results.
