Abstract
An inter-propellant thrust seal for a rocket engine with purge fluid introduced into purge chambers to prevent mixing of reactive fluids located outside of bearings, and where one of the purge chambers is formed by an axial thrust piston on the rotor shaft so that the purge fluid in that chamber will also produce axial thrust on the rotor shaft.
