The invention discloses a flap actuation mechanism and a method for deploying a flap. The flap actuation mechanism includes a flap bracket attached to the flap and coupled to the subwing structure bya pivot coupling. A crankshaft is configured for over-center rotation, the crankshaft having aligned inboard and outboard crank arms extending from axially spaced inboard and outboard journals disposed in an under-wing structure, the inboard and outboard crank arms being coupled to the inboard and outboard crank arms. And the inboard crank arm and the outboard crank arm are configured to rotate about a rotational axis of the inboard journal and the outboard journal. And the crank pin is connected between the inner side crank arm and the outer side crank arm. The actuation lever has a first endrotatably coupled to the crank pin and a second end coupled to the flap bracket. Rotation of the crankshaft displaces the actuation lever to cause rotation of the flap bracket and flap.
本申请公开了一种襟翼致动机构和用于展开襟翼的方法。该襟翼致动机构包括附接到襟翼并通过枢转耦接件耦接到翼下结构的襟翼支架。曲轴构造为用于过中心旋转,该曲轴具有对准的内侧曲柄臂和外侧曲柄臂,内侧曲柄臂和外侧曲柄臂从设置在翼下结构中的轴向间隔开的内侧轴颈和外侧轴颈延伸,并且内侧曲柄臂和外侧曲柄臂构造成围绕内侧轴颈和外侧轴颈的旋转轴线旋转。曲柄销连接在内侧曲柄臂和外侧曲柄臂之间。致动杆具有可旋转地耦接到曲柄销的第一端和耦接到襟翼支架的第二端。曲轴的旋转使致动杆移位,以导致襟翼支架和襟翼的旋转。
