Abstract

See full text

A vane assembly comprises circumferentially adjacent airfoils formed of composite materials. The airfoils have matching exterior geometries defined by pressure and suction surfaces extending axially from a leading edge to a trailing edge and radially from a root section to a tip section. An inner platform is attached to each of the circumferentially adjacent airfoils at the root section, and an outer platform is attached at the tip section. The composite materials are selected to define a vibration mode with different vibration frequencies in the circumferentially adjacent airfoils, where the different vibration frequencies are separated by more than a full width of the vibration mode at half maximum.
