本公开涉及翼型、降噪装置、涡轮机、飞行器、水运工具与冷却风扇。一种翼型,比如气动翼,该翼型具有前缘和尾缘,该翼型的前缘和尾缘中的一者或两者的至少一部分具有齿形轮廓,齿形轮廓包括多个邻接的齿,每个齿具有表示齿的局部最大弦长方向延伸范围的顶端点,并且在顶端点的每一侧的展长方向上具有根端点,根端点表示齿的局部最小弦长方向延伸范围,并且在根端点处,齿与相应的相邻的齿邻接,其中,齿边轮廓在顶端点与根端点之间以Ogee型曲线变化,使得齿在顶端点的邻域中和根端点的邻域中比在顶端点与根端点之间的位置处更尖锐。

    A foil, such as an aerofoil, having a leading edge and a trailing edge, of which at least a portion of one or both of the leading edge and trailing edge has a serrated profile comprising a plurality of adjoining teeth, each tooth having a tip point that represents a local maximum chord-wise extent of the tooth and, on each side span-wise of the tip point, a root point that represents a local minimum chord-wise extent of the tooth and at which the tooth adjoins a respective adjacent tooth, wherein the tooth edge profile varies with an ogee-like curve between tip point and root point such that the tooth is sharper in the neighbourhood of the tip point and in the neighbourhood of the root point than at locations in between.
