the first profile 52 varies in the radial distance it is disposed from the engine centerline axis 20 similarly the inner surface 46 below the engine centerline axis 20 is shaped with the second profile 54 which extends generally axially along the engine centerline axis 20 from the forward lip 40 to at least the fan case flange plane 48 the second profile 54 varies in the radial distance it is disposed from the engine centerline axis 20 for most of the axial travel of the first profile 52 and second profile 54 along the engine centerline axis 20 the radial distance the first profile 52 is disposed from the engine centerline axis 20 differs from the radial distance the second profile 54 is disposed from the engine centerline axis 20 thus the volume and cross sectional area of the inlet 18 above the engine centerline axis 20 generally differs from the volume and cross sectional area of the inlet 18 below the engine centerline axis 20 the difference in geometry between the first and second profiles 52 and 54 is approximated by the inlet centerline axis 56 which approximates the geometric center of the inlet 18 which has a cambered shape with respect to the engine centerline axis 20 the inflection point 53 of the first profile 52 is radially and axially offset along the engine centerline axis 20 from the inflection point 55 of the second profile 54 more particularly the convex forward section 54 f when viewed from the engine centerline axis 20 of the second profile 54 extends further rearward toward the fan face plane 50 than does the convex forward section 52 f of the first profile 52 terms such as.
