Patent ID: 8561384

Claim:
A nacelle adapted for receiving therewithin, a gas turbine engine, said nacelle comprising: a fan cowl body having a first axial centerline passing therethrough, a gas turbine engine disposed radially inwardly of said body, said gas turbine engine having a second axial centerline passing therethrough, a fan disposed in said body, a fan duct defined between said body and said gas turbine engine, a pylon that extends between said body and said gas turbine engine, wherein a first area of the fan duct above said first axial centerline and a second area of the fan duct and below said first axial centerline being substantially equal normal to the flow of air discharged from said fan in a region upstream of the pylon and the first area being larger than the second area in a region downstream of the pylon, in amounts to compensate for the pylon, and said first axial centerline and said second axial centerline are slanted relative to each other in the region downstream of the pylon due to the offsetting of said body toward the pylon or due to the offsetting of the gas turbine engine away from the pylon.
