GAS TURBINE ENGINE WITH VARIABLE AREA FAN NOZZLE
First Claim
1. A nacelle assembly for a gas turbine engine comprising:
- a core nacelle defined about an engine centerline axis;
a fan nacelle mounted at least partially around said core nacelle to define a fan bypass flow path; and
a variable area fan nozzle in communication with said fan bypass flow path, said variable area fan nozzle having a first fan nacelle section and a second fan nacelle section, said first fan nacelle section defines an intermittent trailing edge which defines a multiple of ports and said second fan nacelle section defines a multiple of doors, each of said multiple of doors match each of said multiple of ports such that a fan nacelle trailing edge is continuous when said second fan nacelle section is selectively translated to a closed position relative to said first fan nacelle section.

Abstract
A nacelle assembly for a bypass gas turbine engine includes a variable area fan nozzle having a first fan nacelle section and a second fan nacelle section. The variable area fan nozzle is in communication with a fan bypass flow path, the first fan nacelle section defines an intermittent trailing edge which defines a multiple of ports and the second fan nacelle section defines a multiple of doors, each of the multiple of doors match each of the multiple of ports such that a fan nacelle trailing edge is continuous when the second fan nacelle section is selectively translated to a closed position relative to the first fan nacelle section.
