Claim:
An aircraft nacelle, comprising: an air intake ( 50 ) that includes an air intake pipe ( 54 ) located at a front of the nacelle; a power plant ( 52 ) with a fan located within a power plant pipe ( 56 ), the power plant ( 52 ) being located aft of the air intake ( 50 ), the power plant pipe ( 56 ) being an aft extension of the air intake pipe ( 54 ); wherein the air intake pipe ( 54 ) channels air from the front of the nacelle in an aft direction toward the power plant pipe ( 56 ) to channel an incoming stream of air into the power plant pipe ( 56 ), a first primary portion of the incoming stream of air passing through the power plant, and a second secondary portion of the incoming stream of air being entrained by the fan and flowing into an annular pipe that is delimited by an inside wall of the power plant pipe ( 56 ) and an outside wall of the power plant, said air intake pipe ( 54 ) including i) a panel ( 58 ), the panel ( 58 ) integrating an acoustic treatment with an acoustically resistive porous layer ( 60 ) that is in contact with an aerodynamic stream that enters into the nacelle, at least one alveolar structure ( 62 ), and a reflective layer ( 64 ), the reflective layer ( 64 ) forming a rear surface of said panel ( 58 ), and ii) an edge ( 72 ) delimiting the air intake pipe ( 54 ), the edge ( 72 ) being a distal aft portion of the reflective layer ( 64 ) located aft adjacent an aft distal end of the alveolar structure ( 62 ); and a flange ( 66 ) connecting said air intake ( 50 ) and said power plant ( 52 ), said flange ( 66 ) comprising a first wing ( 68 ) connected to a flange of the power plant pipe and a second wing ( 76 ), the second wing ( 76 ) being connected to the reflective layer ( 64 ) forming the rear surface of said air intake ( 50 ) by a number of connecting elements, some of said connecting elements connecting the flange ( 66 ) to the edge ( 72 ) delimiting the air intake pipe ( 54 ), said connecting elements connecting the flange ( 66 ) to the edge ( 72 ) having central longitudinal axes ( 74 ) that are secant with the edge; wherein the flange ( 66 ) comprises, at said second wing ( 76 ) resting against the rear surface ( 64 ) of the panel ( 58 ), for each connecting element, a projection ( 78 ) with an inclined plane ( 80 ) that forms an angle with said second wing ( 76 ), and wherein each said connecting element connecting the flange ( 66 ) to the edge ( 72 ) extends through a corresponding one of said projections ( 78 ) so that the longitudinal axis of each said connecting element is perpendicular to the inclined plane; further comprising, for each connecting element, a structural reinforcement ( 82 ) comprising a top ( 84 ) having an inclined plane ( 92 ), wherein the connecting element is arranged from the projection to the structural reinforcement.
