Abstract: An array of flow directing elements comprises a plurality of flow directing elements 10, 12, 36 mounted to a rotor disk. The plurality of flow directing elements includes a first set of first flow directing elements 10 whose natural vibration frequency has been modified by having material removed from a leading edge tip region 22 and a second set of second flow directing elements 12 whose natural vibration frequency has been modified by having material removed from a midspan leading edge region 24. The array may further comprise unmodified flow directing elements 36 arranged with the modified flow directing elements 10, 12.
