    摘要: A fan duct (5) is defined between an inner skin (2) and an outer skin into which the inner skin of the sliding cover (7) is incorporated in the direct-thrust configuration. The inner skin of the sliding cover (7) comprises an annular part extending radially inwards and capable, in the reverse-thrust configuration, of coming to face a larger-diameter annular part of the inner skin (2) of the fan duct (5). The annular part of the sliding cover (7) comprises at least one flap (8) mounted such that it can pivot between the retracted position and a deployed position in which a front part (8a) of the flap (8), upstream of its middle axis (9) about which it is articulated, projects into the fan duct (5). Translational stop means (11) are provided in order, in the reverse thrust position, to act on a rear part (8b) of the flap (8) in such a way as to cause the flap (8) to pivot into the deployed position to close off the fan duct (5).
