Abstract
Official abstract text for this publication.
A bypass gas turbine engine includes a variable area fan nozzle with a second fan nacelle section axially movable relative to a first fan nacelle section to define an auxiliary port to vary a fan nozzle exit area and adjust fan bypass airflow. The second fan nacelle section includes a leading edge region that defines a concave external contour and the first fan nacelle section includes a trailing edge region that defines a convex internal contour.
First claim
Opening claim text (preview).
What is claimed is: 1. A nacelle assembly for a gas turbine engine comprising: a core nacelle defined about an engine centerline axis of rotation; a fan nacelle mounted at least partially around said core nacelle to define a fan bypass flow path; a variable area nozzle in communication with said fan bypass flow path, said variable area nozzle having a first fan nacelle section and a second fan nacelle section, said second fan nacelle section axially movable relative said first…
