A flywheel system including a rotor shaft. The rotor shaft includes an inner passage therethrough, and a dam with a central opening disposed on a first end of the inner passage. An outer passage surrounds the inner passage. The inner passage is open at a second end, and the outer passage is closed on an end surrounding the second end of the inner passage. The outer passage is open on an end surrounding the first end of the inner passage. Fluid flows into the inner passage at the first end, via the central opening of the dam. Rotation of the flywheel rotor causes the fluid to accumulate along a wall of the inner passage, and to propagate to the second end, where the fluid exits into the outer passage. The fluid propagates along the outer passage to the open end of the outer passage, where it is released.

Self-pumping flywheel cooling system

A method for forming temporary protective coatings and bondable surfaces is disclosed. In the method, a soluble layer is disposed on a material surface, such as the interior surfaces of cell walls of a web material. The soluble material is then removed or leached from the web material to form and expose a roughly textured, bondable surface for bonding with another material, such as AVCOAT insulation. Use of the soluble layer, therefore, enhances the bondability of any surface that requires good adhesion, such as where the surface is difficult to reach for conventional surface preparation techniques.
