The aero-servo-elastic predesign of an active trailing edge located in the range of 50 to 100% spanwise position of an adaptive helicopter rotor blade is presented. The investigated active trailing edge consists of a multi-morph bender including piezoelectric actuators and glass fibre reinforced plastics. The geometry of the active structure is optimized using an evolutionary algorithm with the target to maximize aerodynamic effectiveness in terms of servo effect, i.e. pitching moment [delta]Cm.
