1. An aircraft component having an air ejection device, the aircraft component comprising:

  • a profile provided with a first opening and an ejection nozzle opening into the first opening, wherein dimensions of the first opening change over the length of the profile, and wherein a rate of air flow ejected from the first opening varies along the length of the profile; and

    a flexible tongue rigidly fixed to the profile in the continuity of the profile in such a way as to obstruct the first opening during the phases of flight for which the ejection of air is unnecessary, the flexible tongue being able to flex under the effect of a pressure differential between the air situated in the ejection nozzle and outside air during the phases of flight for which air is ejected.
