Summary: | A nacelle inlet for channeling airflow to a gas turbine engine having a longitudinal centerline axis includes an annular forward nacelle having a leading edge defining an inlet face for receiving the freestream airflow. A diffuser is disposed in flow communication with the inlet face, with the diffuser being defined about a droop axis inclined relative to the engine centerline axis. The forward nacelle includes a crown and a keel defining therebetween a scarf axis, with the keel extending axially forwardly of the crown so that the scarf axis forms an acute scarf angle greater than zero relative to a reference line perpendicular to the droop axis. |
