Experimental setup description ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],From the initial studies related to the optimal configuration of the flexible structure, two actuation lines , positioned at 25.3% and 47.6% of the chord from the airfoil leading edge.

Model of the flexible structure The reference airfoil is the NLF airfoil, WTEA.
