A simple-hinged flap assembly for a winged aircraft includes a simple-hinged flap having a leading airfoil section pivotably connected to a trailing airfoil section via a hinge, and an active flow control (AFC) actuator assembly. The assembly is connected to or integrally formed with the flap and includes upstream and downstream AFC actuators arranged in respective first and second rows, and collectively configured to provide first and second outlet mass flowrates. The downstream AFC actuators emit the second outlet mass flowrate at a rate that substantially exceeds the first outlet mass flowrate, such that the first outlet mass flowrate preconditions a boundary layer around the simple-hinged flap assembly. A winged aircraft includes a pneumatic power supply, fuselage, a wing connected to the fuselage, and the simple-hinged flap assembly.
