This one is mostly a visual post. When I was drawing the sequence of the minor kites’ folding wings I started to feel a bit uncertain about the actual geometry of what I was drawing. The first fold was easy, but when I flipped the hind appendages, my spatial rendering device (brain) started maxing-out.
So, I decided to create a physical model:
The results showed me that despite the aforementioned “max-out”, I got it roughly right.
One thing that the paper models didn’t fully cover was the articulation of the hind appendages: the drawn model folds them back and holds them flush against the flanks. The paper model just goofily kept them splayed. Beyond that, the hind quarters are not supposed to rest on the hind limbs, which are too weak to carry the kite’s weight for long. Instead, what appears to be the “tail” serves as a single back-foot.
The other aspect that the model couldn’t account for is the elasticity of the flying membranes. Being living creatures, minor kites are not rigid like paper. Their flying membranes stretch out for flight and contract when the limbs retract.
It was a fun little experiment. Compare to the drawings from last post:
