包括壁的部件,该壁包括第一区域(541)、第一区域(541)和第二区域(542),肋的网络形成在第一区域(541)、第二区域(542)上以及也形成在过渡区域(54t)上,以便当空气流沿着所述壁流动时减小部件的阻力;在过渡区域(54t)上形成的肋的高度、宽度和间距沿着所述过渡区域(54t)变化,以便从在过渡区域的第一端处的形成在第一区域上的肋的高度、宽度和间距转变到在过渡区域(54t)的第二端处的形成在第二区域(542)上的肋的高度、宽度和间距,过渡区域(54t)包括中心部分,中心部分上的肋一方面包括分别与第一区域(54)上的肋的高度和宽度相等的高度和宽度,另一方面包括与第二区域(542)的肋的间距相等的间距。

    Part comprising a wall which comprises a first zone (541), a first zone (541) and the second zone (542), a network of riblets being formed on the first zone (541), the second zone (542) and also on the transition zone (54t) so as to reduce the drag of the part when a flow of air flows along said wall; the height, the width and the spacing of the riblets formed on the transition zone (54t) changing along said transition zone (54t) so as to pass from the height, width and spacing of the riblets formed on the first zone at a first end of the transition zone to the height, width and spacing of the riblets formed on the second zone (542) at a second end of the transition zone (54t), the transition zone (54t) comprising a central portion on which the riblets comprise on one hand the height and the width that are respectively equal to the height and width of the riblets on the first zone (541), and on the other hand a spacing equal to the spacing of the riblets of the second zone (542).
