Research on Dragonfly’s wing structure and geometry


Dragonfly's wings are formed with various shapes and areas repeating continuously in a pattern. It is a natural construction that determines its sex, breeds and functions. The shapes contained could be divided into three, which are four sided, five sided and six sided geometry. The shapes and its areas must be in place and accurate to be the certain part of the wing for a certain function.

The area of the shape decides on its flexibility and rigidity which are used for flight. As the area of shape increases, the flexibility increases together, and vice versa, as the area of shape decreases, it gets more rigid and straight. As well as its flexibility and rigidity, shapes and areas and the thickness of the branch handles with different forces and generates its tensile forces. The connection between the two shapes allows the whole entire wing to bend and fly.

The importance of the geometry in dragonfly's wings are very interesting and how they all must be in that certain shapes and sizes to link together and be one. Repeated patterns and its shapes and sizes are interesting to alter and see how the form changes as the numbers of sides and areas increase. As shown in the image, when it’s closely looked, the branch has its own thickness and height. Starting from its body, the branch thickness reduces as it gets to the edge of the wing.
