Abstract
An example turbomachine exhaust flow diverting assembly includes an upstream flow diverter disposed about a rotational axis of a turbomachine, and a downstream flow diverter disposed about the rotational axis and axially misaligned with the upstream flow diverter, the upstream flow diverter and the downstream flow diverter both independently moveable between a first position and a second position, the first position permitting more bypass flow from a bypass flow passage to a core flow passage than the second position.
Claims16
A turbomachine exhaust flow diverting assembly, comprising:
- an upstream flow diverter disposed about a rotational axis of a turbomachine, radially outward of a turbine exhaust case, and between a core flow passage and a main bypass passage;
- and
- a downstream flow diverter disposed downstream of the upstream flow diverter about the rotational axis and axially misaligned with the upstream flow diverter, radially outward of the turbine exhaust case, and between the core flow passage and the main bypass passage, the upstream flow diverter being moveable between a first upstream flow diverter position and a second upstream flow diverter position, the downstream flow diverter being moveable between a first downstream flow diverter position and a second downstream flow diverter position, the upstream flow diverter and the downstream flow diverter being independently moveable, and each of the first upstream flow diverter position and the first downstream flow diverter position permitting more bypass flow from a main bypass flow passage to the core flow passage than the corresponding one of the second upstream flow diverter position and the second downstream flow diverter position.
A turbomachine assembly, comprising:
- a core flow passage extending axially from a fan section to an exhaust;
- a radially inner bypass flow passage that is radially outside the core flow passage;
- a radially outer bypass flow passage that is radially outside the radially inner bypass flow passage;
- an upstream flow diverter disposed about a rotational axis of a turbomachine and radially outward of an exhaust case;
- and
- a downstream flow diverter disposed downstream of the upstream flow diverter about the rotational axis and axially misaligned with the upstream flow diverter, radially outward of the turbine exhaust case, and between the core flow passage and the radially inner bypass flow passage, the upstream flow diverter being moveable between a first upstream flow diverter position and a second upstream flow diverter position, the upstream flow diverter and the downstream flow diverter being independently moveable, and each of the first upstream flow diverter position and the first downstream flow diverter position permitting more bypass flow from the radially inner bypass flow passage to the core flow passage than the corresponding one of the second upstream flow diverter position and the second downstream flow diverter position.
