Abstract
A propulsor actuation system for a turbine engine that includes a plurality of propulsor blades each rotatable about a pitch axis. The propulsor actuation system includes one or more actuators having a yoke, and a minimum pitch lockout system. The minimum pitch lockout system includes a locking mechanism movable to a closed position to prevent the yoke from moving axially beyond the locking mechanism such that the propulsor blades are rotatable in a first pitch range, and movable to an open position to allow the yoke to move axially beyond the locking mechanism such that the propulsor blades are rotatable in a second pitch range. A method of operating the propulsor actuation system includes preventing the yoke from moving axially beyond the locking mechanism in the closed position, opening the locking mechanism to the open position, and moving the yoke axially beyond the locking mechanism in the open position.
