GAS TURBINE ENGINE AIRFOIL CURVATURE

摘要

A gas turbine engine includes an array (63) of airfoils (70). Each airfoil (70) includes a first circumferentially extreme position (88). The first circumferentially extreme positions (88) of the airfoils (70) are circumferentially spaced apart from one another a pitch (P). Each airfoil (70) includes a second circumferentially extreme position (90) circumferentially spaced from the first circumferentially extreme position (88) in an angular spacing that is at least one half the pitch (P).
