Integrated design approaches for an innovative multifunctional flap architecture based on distributed electromechanical actuation

An innovative adaptive architecture was defined for the wing flap of a large civil transport aircraft with the scope of improving high-lift performances and wing efficiency in cruise. The adaptation of the flap shape follows three different morphing modes and is ensured by a smart robotic structure driven by electric actuators combined with powerful transmission lines. For robotic morphing architectures, the design of the actuation system needs to be carried out in combination with the supporting structure as they both participate in withstanding the operative loads. The integrated approaches adopted for the design of the morphing flap structure and embedded actuation have been outlined in this work; the outcomes of each design phase have been presented and critically analyzed.
