This paper investigates and characterizes the aerodynamic performance of a unique platform of airfoils with inflatable, elastomeric actuators. By controlling the actuators integrated in 3D-printed airfoils, it is possible to manipulate aerodynamic lift and drag. The pseudo flap can increase lift by a factor of 20-300%. The top-front inflated design increases lift and stalling angle at high angles of attack (>12 °). Comparisons between numerical simulations and experiments verify the efficacy of the outlined approach. This work is the first to describe the dynamic fluid-soft material interactions for both lift and drag of inflatable actuators embedded in stiff structures.
