<p>A fixed upstream seal is provided having a variable geometry to provide a maximum body thickness at points of large deflection and a minimum body thickness at points of small deflections with the body thickness varying in progressively from maximum to minimum and minimum to maximum for predetermined halves of the circular seal. Also, a fixed downstream seal is provided having a variable geometry to provide minimum body thickness at points of large axial rotor deflection.</p> |
