AIRCRAFT FLAP

An aircraft flap (10) that excludes an actuation structure providing an air jet. The aircraft flap comprises at least one side-edge opening that is connected to one or more air channels for directing an airflow in and/or out to reduce the structural strength of a vortex system of a side edge of the flap, wherein the air channel passes through a first surface and a second surface of the flap, and thus a first side-edge opening is formed in the first surface, and a second side-edge opening is formed in the second surface; and one of the first surface and the second surface is a side surface (11) of the flap, and one of the first side-edge opening and the second side-edge opening is a side-surface opening (110, 120). The aircraft flap can reduce aerodynamic loss while ensuring a noise reduction effect, and has a simple structure and good practicability.
