Abstract
Official abstract text for this publication.
A gas turbine engine includes a core defining an engine central longitudinal axis. An inner-fixed structure is radially outward of the core. A core cowl extends from the inner-fixed structure to a trailing edge. A thrust reverser is spaced radially outward of the core cowl to define a fan flow path. A vent has a core cowl inner surface formed as part of the core cowl and a vent inner surface that is spaced radially inward of the core cowl inner surface to define a vent flow path. A reflex member extends from a trailing edge of the core nacelle to impede mixing of the fan flow path and the vent flow path.
First claim
Opening claim text (preview).
What is claimed is: 1. A nacelle assembly for a gas turbine engine comprising: a core defining an engine central longitudinal axis; an inner-fixed structure radially outward of the core and having a core cowl that extends from the inner-fixed structure to a trailing edge; a thrust reverser spaced radially outward of the inner-fixed structure to define a fan flow path; a vent having a core cowl internal surface formed as part of the core cowl and a vent inner surface spaced r…
