Abstract

An aircraft propulsion system (20) assembly includes a plurality of airfoils (110) and an actuation system (106). Each of the airfoils (110) projects radially outward from a respective airfoil base (108) to a respective airfoil tip (118). The airfoils (110) include a first airfoil (110) and a second airfoil (110). The actuation system (106) is configured to pivot the first airfoil (110) about a first airfoil pivot axis (128) from a first airfoil first pitch position (129A), through a first airfoil feather pitch position (129C), to a first airfoil second pitch position (129E). The actuation system (106) is configured to pivot the second airfoil (110) about a second airfoil pivot axis (128) from a second airfoil first pitch position (129A), through a second airfoil feather pitch position (129C), to a second airfoil second pitch position (129E). The actuation system (106) is configured to asynchronously schedule pivoting the first airfoil (110) through the first airfoil feather pitch position (129C) with pivoting the second airfoil (110) through the second airfoil feather pitch position (129C).
