Abstract
The present invention relates to an improved array of flow directing elements for incorporation in turbomachinery. In accordance with the present invention, an array of flow directing elements comprises a plurality of flow directing elements mounted to a rotor disk. The plurality of flow directing elements includes a first set of first flow directing elements whose natural vibration frequency has been modified by having material removed from a leading edge tip region and a second set of second flow directing elements whose natural vibration frequency has been modified by having material removed from a midspan leading edge region. The array may further comprise unmodified flow directing elements arranged with the modified flow directing elements.
