A gas turbine engine includes a set of circumferentially adjacent airfoils having outer walls defining a pressure side and a suction side, extending between a leading edge and a trailing edge to define a flow direction, and extending between a root and a tip to define a span direction; and a set of dimples disposed on an outer wall of the at least one airfoil, the set of dimples being spaced apart in at least one of a flow direction or a span-wise direction. 一种燃气涡轮发动机，包括：一组周向相邻的翼型件，该翼型件具有外壁，该外壁限定压力侧和吸力侧，在前缘和后缘之间延伸以限定流向方向，并且在根部和尖端之间延伸以限定翼展方向；以及一组凹痕，该凹痕设置在至少一个翼型件的外壁上，该组凹痕在流向方向或翼展方向中的至少一个方向上间隔开。
