1. From isothermal finite element calculations of skirt with crown, no gap closure.

2. From finite Clement calculations and estimates based on experiments.

3. Maximum crown / skirt lift-off distance in mils based on crown / skirt model.

4. From crown / skirt interaction model.

5.. Equals %ax with no lift-off if a = 0, adjusted from finite element %ax t

with lift-off if at > 0 by use of crown / skirt interaction model.
