Morphing mechanisms, inspired by biological fliers, offer a lucrative option for controlling aircraft geometry for mitigating adverse aeroelastic phenomena, and potentially using the aircraft flexibility of the aircraft to our advantage. But, in order to enable morphing aircraft, there is a need to determine suitable morphing mechanisms; develop materials and actuation techniques for practical application; and develop a design optimization framework for detailed structural design (with aeroelastic considerations) for a select vehicle concept. We have been developing AMuBA (Aeroservoelastic Multifidelity Design of Biomimetic Aircraft) – a tool for efficient Multidisciplinary Design Optimization (MDO) of aeroelastic aircraft. AMuBA enables aeroservoelastic analysis with Finite Element Analysis (FEA)-based structural sizing within the conceptual design environment. In order to facilitate the coupling between medium-fidelity aerodynamics and high-fidelity structures, a parametric geometry modeling capability has also been developed. These capabilities are being integrated in an MDO environment. The initial target for application is the alleviation of aileron control reversal. A controllable camber morphing mechanism concept has been developed for this purpose, and the mechanism is being implemented in hardware. Additive Manufacturing (AM) is used to develop the complex mechanisms, which will be actuated by Pneumatic Artificial Muscles (PAMs). This paper describes our ongoing efforts in development of the software architecture (including analyses, automation, and optimization framework).
