Abstract
A gas turbine engine includes an array of airfoils that include first and second segments. The first segment includes a first number of airfoils that are circumferentially spaced from one another a first angular spacing. The second segment includes a second number of airfoils that are circumferentially spaced from one another a second angular spacing. A sum of the first and second number of airfoils corresponds to a total number of airfoils in the array. The first angular spacing is based upon a first effective number of total airfoils in the array that is different than the total number of airfoils.
