An aerodynamic control surface assembly includes a structure (2) with an aerodynamic surface (8) and a curved aerodynamic control surface (20) configured to move between an extended (24) and a retracted position (22). The actuation mechanism (52, 152, 252) is coupled to the aerodynamic control surface (20) and configured to move the aerodynamic control surface (20) between the extended and retracted positions. The aerodynamic control surface is arranged to deploy through an aperture (18) in the aerodynamic surface and into an oncoming airflow (A) over the aerodynamic surface (8) when in the extended position (24) and is arranged to retract out of the airflow when in the retracted position (22). The actuation mechanism (52, 152, 252) is configured such that the control surface (20) follows a curved kinematic path (40, 140, 240) as the control surface moves between the extended (24) and retracted positions (22). The actuation mechanism (52, 152, 252) remains fully behind the aerodynamic surface (8) throughout the movement of the aerodynamic control surface (20) between the extended (24) and retracted positions (22).
