Abstract
A variable area exhaust mixer is provided for a gas turbine engine. The variable area exhaust mixer includes an outer wall with a multiple of doors. Each of the multiple of doors is operable to control a passage entrance into at least one of a multiple of circumferentially arrayed vanes with a respective strut flow passage which essentially alters its bypass ratio during flight to match requirements.
Claims11
A variable cycle gas turbine engine, comprising:
- a variable area exhaust mixer between a third stream fan flow path and a core flow path;
- the variable area exhaust mixer operable to control flow from the third stream fan flow path to the core flow path through a multiple of circumferentially arrayed vanes.
A method of operating a gas turbine engine comprising selectively changing an area-ratio between a fan flow in a third stream bypass flow path and a core flow through a core flow path downstream of a turbine section.
