Slotted cruise trailing edge flap

机译:开槽巡航后缘襟翼

摘要

A slotted cruise trailing edge flap (16) having a single-slotted configuration during cruise, and a double-slotted configuration during takeoff and landing is disclosed. The slotted cruise trailing edge flap (16) includes a flap assembly (18) positioned along the trailing edge of an aircraft wing (30). The flap assembly (18) includes a vane element (22) and a main element (24) mounted in a fixed relation to one another that defines a slot (25) therebetween. The slotted cruise trailing edge flap also includes an extension assembly (20) that includes a support structure (23) from which the flap assembly (18) is translatably connected via a track (44) and carriage (46) arrangement. The flap assembly (18) is rotatably connected to the support structure (23) using a cam follower (52) and cam slot (50). An actuation mechanism (28) including a rotary actuator (56) moves the flap assembly (18) relative to the support structure (23). In a stowed position, the vane element (22) preferably nests into the wing (30) such that the slot (25) remains available to direct airflow from the wing lower surface to the wing upper surface. In an extended position, the vane and main elements (22), (24) form a double-slotted arrangement created by the flap assembly translating rearward and rotating downward relative to the wing (30).
