Turbine engine with thrust vectoring exhaust nozzle

摘要

A turbine engine exhaust nozzle includes a core gas duct, a nozzle duct, and a thrust vectoring duct system having a duct valve, a first vectoring duct and a second vectoring duct. The nozzle duct directs a first portion of core gas from the core gas duct through a nozzle duct outlet along a centerline. The duct valve connects the core gas duct to the first vectoring duct during a first mode of operation, and connects the core gas duct to the second vectoring duct during a second mode of operation. The first vectoring duct directs a second portion of core gas from the core gas duct through a first vectoring duct outlet along a first trajectory. The second vectoring duct directs a third portion of core gas from the core gas duct through a second vectoring duct outlet along a second trajectory that is angularly offset to the first trajectory.

1. A turbine engine exhaust nozzle, comprising:
a core gas duct; a nozzle duct extending along a longitudinal centerline to a nozzle duct outlet, wherein the nozzle duct directs a first portion of core gas from the core gas duct through the nozzle duct outlet along the centerline during a first mode of operation and a second mode of operation; and a thrust vectoring duct system comprising a duct valve that connects the core gas duct to a first vectoring duct during the first mode of operation, connects the core gas duct to a second vectoring duct during the second mode of operation, and disconnects the core gas duct from the first vectoring duct during the second mode of operation; wherein the first vectoring duct comprises a first vectoring duct outlet, and directs a second portion of core gas from the core gas duct through the first vectoring duct outlet along a first trajectory; wherein the second vectoring duct comprises a second vectoring duct outlet, and directs a third portion of core gas from the core gas duct through the second vectoring duct outlet along a second trajectory that is angularly offset to the first trajectory and diverges laterally away from the centerline; and wherein the first vectoring duct is laterally between the nozzle duct and the second vectoring duct.
