摘要： An exhaust nozzle assembly (18) for a gas turbine engine (10), the assembly (18) comprises a main axis (20), an inner nozzle (19), an outer nozzle (17), a translatable centre-body (44) and a means for translating the centre-body (49) between a forward position and a rearward position. The centre-body (44) is disposed radially inwardly of the inner nozzle (19) thereby partly defining an inner duct (35) for a core engine gas flow (28), an outer duct (17) for a bypass gas flow (30) is defined by the inner nozzle (19) and the outer nozzle (17). The outer nozzle (17) extends downstream of the inner nozzle (19) and with the centre-body (44) defines a final mixing duct (36) having a final exhaust exit area (38). When the centre-body (44) is in the forward position the final exhaust exit area (38) is at a maximum area, and when the centre-body (44) is in a rearward position the final exhaust exit area (38) is at a minimum area.
摘要翻译：一种用于燃气涡轮发动机（10）的排气喷嘴组件（18），所述组件（18）包括主轴（20），内喷嘴（19），外喷嘴（17），可平移中心体（44））和用于在中间体（49）向前位置和向后位置之间平移的装置。中心体（44）设置在内部喷嘴（19）的径向内侧，从而部分地限定用于核心发动机气体流（28）的内部管道（35），用于旁路气体流动的外部管道（17））由内部喷嘴（19）和外部喷嘴（17）限定。外喷嘴（17）延伸到内喷嘴（19）的下游，并且中心体（44）限定具有最终排气出口区域（38）的最终混合管道（36）。当中心体（44）处于向前位置时，最终排气出口区域（38）处于最大区域，并且当中心体（44）处于向后位置时，最终排气出口区域（38）为在最小面积。
