Experimental Study on Wing Twist-Morphing Structure Using a Double-Tube Cylinder

抄録

In this study, a design method is proposed and validated through experimental demonstration of a wing twist-morphing structure using a double-tube cylinder equipped with ribs at its closed section member. The details of the experiments are as follows: (i) specimens were made in accordance with the design method proposed, (ii) specimens were twisted and measured using a photogrammetric measurement system, and (iii) the twist angle of each rib was calculated by measuring the movement of each marker. The validity of the design method was evaluated by comparing the results between theoretical values and experimental values. Although the values obtained from the experiments are found to be lower than those obtained from theoretical calculations, especially at the wing-tip side, the trend is still in line with the theory. This indicates that the method derived is effective and applicable to designing wing twist-morphing structures.
