Abstract
A hydraulic seal for a tip turbine engine includes an inner radial flange and an outer radial flange. The inner radial flange rotates relative to the outer radial seal section and the planet carrier face to prevent lubrication from entering into the air flow streams within the engine without additional engine assembly procedures.
