    • The invention relates to gas turbine engines and a method for controlling gas turbine engines. The gas turbine engine having a variable area fan nozzle (40) including a nozzle section that is attachable to the gas turbine engine for influencing flow through the fan bypass passage (30) of the gas turbine engine. The nozzle section (40) is movable between a first length (60) and a second length (60') that is larger than the first length (60) to influence the flow. For example, the nozzle section includes members (56) that are woven together to form collapsible openings (66) that are open when the nozzle section (40) is moved to the first length (60) and that are closed when the nozzle section is moved to the second length (60').
    • 本发明涉及燃气涡轮发动机和一种用于控制燃气涡轮发动机的方法。 该燃气涡轮发动机具有可变面积的风扇喷嘴(40),其包括喷嘴部分,喷嘴部分可连接到燃气涡轮发动机,用于影响通过燃气涡轮发动机的风扇旁通通道(30)的流动。 喷嘴部分(40)可在大于第一长度(60)的第一长度(60)和第二长度(60')之间移动以影响流动。 例如,喷嘴部分包括被组装在一起以形成可折叠开口(66)的构件(56),当可以将喷嘴部分(40)移动到第一长度(60)时打开,并且当喷嘴部分是 移动到第二长度(60')。
