Patent ID: 8424810

Claim:
A low noise leading edge wing slat, comprising: a front surface; a rigid rear surface converging with the front surface at an upper vertex and at a lower vertex such that the upper vertex abuts an upper surface of an aircraft wing and the lower vertex is proximate to a lower surface of the aircraft wing when the low noise leading edge wing slat is configured in a stowed position against the aircraft wing such that the rigid rear surface between the upper vertex and the lower vertex is hidden from an ambient airflow over the aircraft wing in the stowed position, wherein at least a first portion of the rigid rear surface between the upper vertex and the lower vertex is substantially concave and a cove-filled second portion of the rigid rear surface is substantially convex and lower than the first portion; and a moveable panel, rotatably connected proximate to the lower vertex, configured to rotate downward from the rear surface when the low noise leading edge wing slat is refracted to the stowed position such that the moveable panel bridges a gap width between the lower vertex and the lower surface of the aircraft wing and a distal edge of the moveable panel abuts the lower surface of the aircraft wing, and the moveable panel is also configured to rotate upward toward the cove-filled second portion of the rear surface when the low noise leading edge wing slat is extended away from the aircraft wing.
