    • An axisymmetric nozzle for a gas turbine engine has divergent flaps and seals disposed about a central longitudinal axis thereof. The divergent flaps and seals each have an inner surface defining cooling air inlet holes at an upstream portion, cooling air exit holes at a downstream portion, and cooling air channels disposed within the divergent flap and seal, and communicating at a first end with the inlet holes and at a second end with the exit holes for conducting cooling air therethrough. Some of the exit holes of the divergent flap are disposed along lateral edge regions thereof. The divergent seals are interposed between adjacent divergent flaps, and each include lateral edge regions extending laterally beyond the exit holes. The lateral edge regions of each divergent seal have an outer surface overlying at least a portion of the exit holes of an adjacent divergent flap.
    • 用于燃气涡轮发动机的轴对称喷嘴具有围绕其中心纵向轴线设置的发散的翼片和密封件。 发散翼片和密封件各自具有内表面,其限定在上游部分处的冷却空气入口孔,在下游部分处冷却空气出口孔,以及设置在发散片和密封件内的冷却空气通道,并且在第一端与入口 并且在第二端具有用于传导冷却空气的出口孔。 发散翼片的一些出口孔沿其侧边缘区域设置。 发散的密封件插入在相邻的发散片之间,并且每个都包括侧向延伸超出出口的侧边缘区域。 每个发散密封件的横向边缘区域具有覆盖相邻发散片的至少一部分出口孔的外表面。
