Design and Analysis of a Novel Mechanism for the Morphing of Trailing Edge of an Aircraft Wing

MATEC Web of Conferences, 2018
In this paper, design of a novel deployable scissor-structural mechanism (SSM) for active camber and chord morphing airfoil has been presented. The mechanism is created via combination of one four-bar linkage and various scissor-like elements (SLEs). The
