A reduction in noise radiating from a side of a deployed aircraft flap is achieved by locating a slot adjacent the side of the flap, and then forcing air out through the slot with a suitable mechanism. One, two or even three or more slots are possible, where the slot is located at one or more locations selected from a group of locations comprising a top surface of the flap, a bottom surface of the flap, an intersection of the top and side surface of the flap, an intersection of the bottom and side surfaces of the flap, and a side surface of the flap.

What is claimed as new and desired to be secured by Letters Patent of the United States is: 1. An aircraft flap which reduces noise radiating from a side thereof when the flap is deployed comprising: an outer surface having at least one slot; said at least one slot being located on or adjacent to the side of the flap; a mechanism which forces air out through said at least one slot when the flap is deployed; and said at least one slot being configured to direct the forced air to exit in a direction substantially away from said outer surface and toward a ...
