摘要： A nozzle system includes a multitude of circumferentially distributed divergent seals that circumscribe an engine centerline. Each divergent seal includes a multiple of divergent seal intakes adjacent to a joint structure to receive cooling airflow. Each divergent seal body is manufactured of a metallic hot sheet inner skin and a metallic cold sheet outer skin. The skins form a multiple of longitudinal channels which communicate with a multiple of edge channels formed within the first longitudinal side and the second longitudinal side of each divergent seal. The multiple of edge channels are located transverse to the longitudinal axis and are raked aft to facilitate cooling of the gas path surface of each divergent seal and adjacent divergent flaps.

摘要： A variable geometry exhaust nozzle 10 for a turbine engine includes convergent and divergent flaps 12, 18 that circumscribe a gaspath 26 and define convergent and divergent nozzle sections 30, 32 with a throat 34 therebetween. A projection 56, which resides on the divergent flaps, extends radially inwardly from the nozzle. The nozzle also includes a coolant flowpath comprising an interior space 44 in the nozzle, an intake 58 for admitting coolant C into the interior space, and a coolant outlet 60 aft of the intake for discharging the coolant from the interior space. The intake resides forward of the throat. During operation, a coolant film flows along the radially inner surface of the nozzle. The projection encourages a portion of the coolant film to enter and flow through the the coolant flowpath to convectively cool the nozzle. The location of the intake, forward of the throat, takes advantage of the locally high gaspath pressure to ensure that an adequate quantity of the coolant enters and flows through the coolant flowpath.
摘要翻译： 用于涡轮发动机的可变几何形状排气喷嘴10包括会聚和发散的折板12,18，其包围气体路径26并且限定会聚和发散的喷嘴部分30,32，其间具有喉部34。 位于发散翼片上的突起56从喷嘴径向向内延伸。 喷嘴还包括冷却剂流路，其包括喷嘴中的内部空间44，用于将冷却剂C进入内部空间的进气口58和用于从内部空间排出冷却剂的进气口后部的冷却剂出口60。 摄入量位于喉咙前方。 在操作期间，冷却剂膜沿喷嘴的径向内表面流动。 该突起促使冷却剂膜的一部分进入并流过冷却剂流动路径以对流地冷却喷嘴。 进气口位于喉部的前方，利用局部较高的气路压力来确保足够量的冷却剂进入并流过冷却剂流路。

摘要： A disclosed lock washer includes a first opening spaced apart from a second opening for receiving fasteners and preventing rotation. A first set of tabs is associated with the first opening and a second set of tabs is associated with the second opening. Each of the first and second set of tabs are bendable to a lock position preventing rotation of a fastener received within a corresponding one of the first opening and the second opening.

摘要： A nozzle system includes a multiple of circumferentially distributed convergent flaps, divergent flaps and inter-flap seals which circumscribe an engine centerline and define the radial outer boundary of a gas path. Each divergent flap includes a multiple of cooling channels with respective intakes and outlets. As the nozzle transitions between positions, the divergent flap seals move relative a divergent flap longitudinal axis to modulate the cooling airflow which enters the separate intakes.
