초록

A nacelle mounted by a pylon below and forwardly of a wing. The wing has a critical zone, which includes an area in the airstream flow about the wing where either of the following conditions occur: 1. The local pressure coefficient in the airstream has an absolute magnitude greater than 0.05, 2. The airstream flow about the airfoil is supersonic. The nacelle and pylon have a critical surface region which is an upper side surface portion of the nacelle and the contiguous pylon surface adjacent to a forwardly swept portion of the wing. The critical contour...
