    • An exhaust vane disposed in a divergent section of an aircraft gas turbine engine exhaust nozzle is sideways pivotable about a vane pivot axis. The nozzle vane pivot axis may be centrally located at an unvectored nozzle throat. Transversely spaced apart upper and lower tips of the exhaust vane may be incorporated to sealingly engage a nozzle outer wall along upper and lower surfaces of the outer wall of the nozzle. The exhaust vane has flat or contoured vane sidewalls and contoured vane sidewalls may be concave. The exhaust vane may have transversely biased apart upper and lower vane sections extending transversely inwardly from the upper and lower tips of the exhaust vane respectively. The exhaust vane may be articulated having upstream and downstream sections separately sideways pivotable about the vane pivot axis and a second pivot axis downstream of and parallel to the vane pivot axis respectively.
    • 布置在飞机燃气涡轮发动机排气喷嘴的发散部分中的排气扇可围绕叶片枢转轴线侧向枢转。 喷嘴叶片枢转轴线可以位于未打开的喷嘴喉部的中心。 可以结合排气叶片的相对间隔开的上部和下部尖端,以沿着喷嘴的外壁的上表面和下表面密封地接合喷嘴外壁。 排气叶片具有平坦或轮廓的叶片侧壁,并且轮廓叶片侧壁可以是凹形的。 排气叶片可以具有横向偏置的上部和下部叶片部分,分别从排气叶片的上部和下部末端横向向内延伸。 排气叶片可以铰接,其具有分别侧向地围绕叶片枢转轴线枢转的上游和下游部分,以及分别在叶片枢转轴线的下游并平行于叶片枢转轴线的第二枢转轴线。
