Hydraulic Flip Behavior in Typical Liquid Rocket Operating Regimes

Abstract

An experimental investigation on hydraulic flip behavior at typical liquid rocket injector design and operating conditions was completed. Both nitrogen tetroxide and water were used as test fluids. The results were analyzed to show the effect of chamber pressure, orifice L/D, orifice diameter and cross-flow velocity on the occurrence of hydraulic flip. Comparison of experimental results with the theoretical models developed by Ito was made. It was concluded that chamber pressure and orifice L/D strongly affect the occurrence of hydraulic flip while orifice diameter and cross-flow velocity influence hydraulic flip to a much lesser degree. The theoretical models were found to be inadequate for predicting hydraulic flip. The conditions for the occurrence of flip appear nearly the same for both nitrogen tetroxide and water.
