Abstract:
1. An aircraft comprising: a tail boom extending in a longitudinal direction, the tail boom including a tail plane provided with an airfoil surface extending in a transverse direction; at least one stabilizer portion provided with the airfoil surface and extending laterally outside the tail boom and with a central portion extending inside the tail boom, the stabilizer portion being implanted in an orifice defined by a peripheral wall of the tail boom; a clearance existing between the stabilizer portion and the peripheral wall; combating means for combating the phenomenon of flutter, which combating means are provided with stiffener means arranged in the clearance; and at least two tabs included on the stiffener means for exerting compression stress on the stabilizer portion; each tab being in contact with an outer covering of the stabilizer portion and the tail boom, each tab being provided with fastener means receiving in a housing, wherein the stiffener means is compressed between the fastener means and the stabilizer portion, the stiffener means then being in contact with the at least one stabilizer portion, the stiffener means being locked in the housing in an elevation direction by a fastener plate of the fastener means and by the stabilizer portion, and in a plane contained between the fastener plate and the stabilizer portion by a side edge of the fastener means and by closure means, the side edge extending from the fastener plate towards the stabilizer portion without reaching the stabilizer portion, said closure means being removable and co-operating with said fastener means, wherein the two tabs are spaced apart in the longitudinal direction.
