<p>A nacelle assembly (12) includes a first portion having an outer fairing and a trailing edge, and a translatable variable area fan nozzle (50). The fan nozzle (50) includes two or more nozzle segments (54, 56), each nozzle segment having first and second opposed ends and a leading edge. The nozzle segments (54, 56) are selectively movable between a stowed position and one or more deployed positions. In the deployed position, an upstream bypass flow exit (60) is formed between the trailing edge and the leading edge. The nacelle assembly (12) further includes a guide mechanism (104) for guiding the nozzle segments (54, 56) between the stowed position and the deployed position. A split beavertail fairing shields the guide mechanism against air flow when the nozzle segments are in the stowed position.</p> |
