PURPOSE: To provide an elliptical nacelle having a minimum vertical height with improved airflow characteristics used for an aircraft engine. CONSTITUTION: A nacelle 90 has an inlet 92 whose front view portrays an elliptical shape and whose side view represents an arcuate profile. The arcuate profile is determined by three hilite points located at an extreme top position 94, a side position 98, 100, and an extreme bottom position 96 of the nacelle. Each hilite location is set at an individually predetermined distance from a plane which is perpendicular to an inlet centerline.
