Validation of a smart structural concept for wing-flap camber morphing
Rosario Pecora,Francesco Amoroso,Gianluca Amendola,Antonio Concilio 국제구조공학회 2014 Smart Structures and Systems, An International Jou Vol.14 No.4
The study is aimed at investigating the feasibility of a high TRL solution for a wing flap segment characterized by morphable camber airfoil and properly tailored to be implemented on a real-scale regional transportation aircraft. On the base of specific aerodynamic requirements in terms of target airfoil shapes and related external loads, the structural layout of the device was preliminarily defined. Advanced FE analyses were then carried out in order to properly size the load-carrying structure and the embedded actuation system. A full scale limited span prototype was finally manufactured and tested to: • demonstrate the morphing capability of the conceived structural layout; • demonstrate the capability of the morphing structure to withstand static loads representative of the limit aerodynamic pressures expected in service; • characterize the dynamic behavior of the morphing structure through the identification of the most significant normal modes. Obtained results showed high correlation levels with respect to numerical expectations thus proving the compliance of the device with the design requirements as well as the goodness of modeling approaches implemented during the design phase.
