This paper presents a preliminary design optimization of a new Advanced Active Twist Rotor (AATR-II) blade incorporating single crystal Macro Fiber Composites (MFC). Due to the high actuation performance of the single crystal MFC, the AATR-II blade may reduce the helicopter vibration more efficiently even with a lower input-voltage as compared with the previous ATR blades. In preliminary design, influences of the single crystal MFC on the structural and actuation properties of the AATR-II blade are investigated. In design optimization, an optimal cross-section configuration is obtained to maximize the twist actuation. In order to maintain the properties of the original ATR blade, various constraints and bounds are considered for the design variables selected. For design optimization, various numerical tools, such as two-dimensional cross-section analysis, one-dimensional exact beam analysis, gradient-based optimizer with MATLAB, and other related analysis modules, are used. The resulting cross-section configuration of the AATR-II blade achieves the target twist actuation with the minimum input-voltage.
