초록

In a scarfed nacelle inlet for channeling airflow to an engine having a longitudinal center line axis (ENGINE C/L), the duct including a crown (26) and a keel (28), an improvement including an inlet with a biplanar forward hilite. When viewed in side elevation, the biplanar hilite includes a first portion (40) including the keel, a second portion (42) including the crown, and a transition region (44) between the first and second portions. The first and second portions (40), (42) are linear and the transition region (44) is a single arc. An imaginary inte...
