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.
Claims8
A variable area exhaust mixer combining a core stream from a core of a gas turbine engine with a bypass stream bypassing the core, the variable area exhaust mixer comprising:
- a multiple of circumferentially arrayed vanes each having a respective strut flow passage internal thereto, each respective strut flow passage is open at a radially outbound end to a respective plenum, each respective plenum having a passage entrance;
- an outer wall with a multiple of doors;
- the passage entrance of each respective plenum is operable to be opened and closed by at least one of the multiple of doors, to thereby control flow of the bypass stream through each respective strut flow passage and the respective plenum,
- wherein each of the multiple of doors is hinged along the outer wall about a rotational axis that is parallel to a central longitudinal engine axis of the gas turbine engine.
