This paper demonstrates a technique for locating the optimal control surface layout of an aeroservoelastic Common Research Model wingbox, in the context of maneuver load alleviation and active flutter suppression. The combinatorial actuator layout design is solved using ideas borrowed from topology optimization, where the effectiveness of a given control surface is tied to a layout design variable, which varies from zero (the actuator is removed) to 1 (the actuator is retained). These layout design variables are optimized concurrently with a large number of metallic structural wingbox sizing variables and control surface actuation variables to minimize the sum of structural mass and actuator mass. The results demonstrate interdependencies between structural sizing patterns and optimal control surface layouts for both static and dynamic aeroelastic physics.
