A nacelle inlet lip has a simplified geometry. The nacelle inlet lip has a constant cross-section all along a circumference thereof and is wholly concentric relative to the engine centerline, thereby allowing for the use of simple and economical manufacturing processes.


1. A nacelle inlet for a turbofan engine having an engine centerline, comprising an annular inlet lip mounted to an inlet section of the nacelle, the annular inlet lip being made from a single continuous piece of material separate from that of the inlet section, the annular inlet lip being concentric relative to the engine centerline, the annular inlet lip having a constant cross-section all along a circumference thereof, the annular inlet lip having an external surface and an internal surface joined by a rounded leading edge, the external surface being ...
