1. An aircraft comprising:
a wing including:
a fixed wing portion supporting a rib;
a flaperon; and
an actuation system including:
a first actuator coupled to the rib, wherein the first actuator is a rotary actuator to move, at a first rate of movement, the flaperon along a first degree of freedom between a stowed position in which the flaperon is aligned with the fixed wing portion and a deployed position in which the flaperon is moved downward relative to the fixed wing portion; and
a linkage assembly coupled between the fixed wing portion and the flaperon, the linkage assembly including:
a rocker coupled to the rib at a first pivot, the rocker coupled to the first actuator at a second pivot, the rocker coupled to the flaperon at a third pivot; and
a second actuator to move, at a second rate of movement greater than the first rate of movement, the flaperon along a second degree of freedom to pitch the flaperon between an upward position and a downward position, the rocker coupled to the second actuator at a fourth pivot.
