    • A thrust vectorable fan variable area nozzle (FVAN) includes a synchronizing ring, a static ring, and a flap assembly mounted within a fan nacelle. An actuator assembly selectively rotates synchronizing ring segments relative the static ring to adjust segments of the flap assembly to vary the annular fan exit area and vector the thrust through asymmetrical movement of the thrust vectorable FVAN segments. In operation, adjustment of the entire periphery of the thrust vectorable FVAN in which all segments are moved simultaneously to maximize engine thrust and fuel economy during each flight regime. By separately adjusting the segments of the thrust vectorable FVAN, engine trust is selectively vectored to provide, for example only, trim balance or thrust controlled maneuvering.
    • 推力可动风扇可变区域喷嘴(FVAN)包括安装在风扇机舱内的同步环,静止环和挡板组件。 致动器组件选择性地相对于静态环旋转同步环段,以调整翼片组件的段以改变环形风扇出口区域,并且通过推力可动的FVAN段的不对称运动来矢量推力。 在操作中,调整可推力矢量FVAN的整个周边,其中所有段同时移动,以在每个飞行状态期间最大化发动机推力和燃料经济性。 通过单独调节推力可矢量的FVAN的段,选择性地引导发动机信任,以提供例如仅修剪平衡或推力控制的操纵。
