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： An extended impingement cooling structure to cool outside an air supply plenum comprises an inner wall; an impingement sheet; a series of supports to maintain the inner wall in spaced relation to the impingement sheet, and a baffle supported between the inner wall and the impingement sheet. The baffle has a collector plenum area that receives impingement cooling air from the air supply plenum and a channel in fluid communication with the collector plenum and extending outside the air supply plenum with openings to allow impingement cooling air to pass therethrough and having a series of lands extending into the channel wherein the lands are located in proximity to impingement cooling air outlets in the inner wall.
