wing streamlined

Also, I was trying to get back into writing with dialogue practice last night. All I got is Artorius doing his dumb bird metaphor with Sorey and Mikleo, and…



Artorius:
Why do you think birds fly?

Sorey: Well, that’s because all animals have to adapt to their environment to survive, right? And many birds are just built for flight – they have wings, streamlined bodies, feathers, and even hollow bones! These are all designs that naturally allow birds to soar high above in the skies.

Artorius: Uh–

Mikleo: Right. And it isn’t just for survival either; some birds are predators and flying helps them hunt prey more efficiently.

Artorius: No, that’s not what I mean–

Sorey: Yeah! It’s also sort of a misconception to say all birds can fly. They might look like they’re built for it, but some birds – like pengyons – can’t fly at all, but are good at catching prey in the water.

Mikleo: Indeed. So, I think the question we should be asking is: why do birds even have wings? What first made them evolve and develop these wings so that they could take flight or swim better in water?

Sorey: Birds are amazing, aren’t they Mikleo? I’d rather be a bat though. Bats can fly and use sonar to find their way in the dark – that’s like, double cool!

Mikleo: Of course you would. You’re the weird one here, after all.

Sorey: Hey, birds of a feather flock together….

Artorius: Can you two nerds stop ruining my metaphor already?

fallenkitty123  asked:

Can you please write a kitty first date?

“Wait you’ve never been to the zoo?” Kit stared at Ty incredulously over a bowl of cereal.

Ty shook his head. “I know what going to the zoo entails, but I’ve never actually been.” He pushed his cheerios around, the silver spoon making a faint clicking sound on his bowl.

Kit stood up, seized by a sudden urge. “We’re going.”

Ty stared at his shoulder. “We are?”

Kit gulped. “Yeah…like a date…you know…um…” He scratched the back of his head. “We’ve never been on a real date.”

Ty’s eyebrows furrowed. “We went to that shitty pizza place that one time after a demon scouting expedition.”

Kit groaned. “Emphasis on shitty pizza place, come on you’ll love the zoo.” Ty rolled his eyes, but he was beginning to smile. Kit’s heart pattered. That smile would be the death of him.

They got into the zoo around 11:30. Ty had wanted to go in glamoured so they wouldn’t have to pay the fee, but Kit had won the argument by telling him about the ice cream that they wouldn’t be able to get glamoured. Ty hadn’t wanted Kit to go back to his old habit of stealing.

“So where to?” Kit asked Ty as they looked at one of the maps. Ty’s finger traced over the little drawings of animals.

“The African Savanna?” He asked uncertainly. These shadowhunters are so confident when they have to murder someone, but at the zoo they’re hopeless. Kit thought.

“Sounds great!” Kit exclaimed, and they made their way to the exhibits.

With some rare ability Ty managed to keep them away from the majority of the crowds. He seemed fascinated by every animal they saw. Kit for his part was content to just stare at Ty as he read the facts that were mounted on plaques next to the exhibits. Sometimes Ty would state another fact that wasn’t on the plaques because he’d made a late night Wikipedia search, or sometimes he’d rant about a certain animal’s eating habits long after they’d left an exhibit behind.

“Did you know that a bald eagle can see for up to two miles?” Ty said excitedly as Kit ordered burgers for them. “And they can dive at up to two hundred miles per hour! Which is determined by how strong their wings are and how streamlined their bodies and feathers are.”

He grabbed both wax paper lined baskets and picked a table for them in the shade underneath a tree. Kit followed with their ice creams. He leaned against his elbows while he munched his fries and listened to Ty talk.

It was a nicely cool day in LA, and Kit was glad he’d chosen this particular day for this particular spontaneous date with this particular boy.

A group of grey haired women sat at the table next to them. Ty went silent and raised his eyebrows at Kit, tilting his head ever so slightly. Time to play their eavesdropping game.

The women were talking about communism and capitalism and the pros and cons of each and which circumstances would destroy economies. Kit almost fell asleep within the first ten seconds of listening. One glance at Ty told him that Ty was as disinterested as he was.

A lull in the women’s conversation brought the comment. “Kids are getting tattoos awful young these days.”

Ty and Kit made abrupt eye contact and Kit stifled a laugh. Ty’s arms were inked up and down with runes and Kit could another peeking out from the edge of his collar. He dropped what was supposed to be a sultry wink at Ty and Ty threw his head back in a giggle.

They hadn’t been to the aquarium so after they finished their ice creams Ty dragged Kit by his shirt to the building. If Kit was being honest with himself he only put up a “struggle” so Ty would keep dragging him.

The aquarium was dark and lit only by blue lights on the floor and the glow from the tanks. Ty’s hand slipped down Kit’s side to clasp his hand. Ty’s fingers were warm. Kit gave a tiny squeeze and watched Ty’s eyes as he observed the fish in quiet, his grey eyes soaking up every detail. Kit didn’t really care about the fish, he only cared about how Ty watched them full of wonder.

More Headcanons Yayy!

Told you I had nothing better to do. Honestly I spend way to much time thinking about this show.


Angels’ Wings pt. 1

Micheal 

As the oldest of the archangels, he has a single pair of wings. His wings are large, probably the largest of any angels. They’re white, pure white, what you think of when you think angels, nothing too extraordinary. They have the faintest golden glow at the tips of the feathers. Sleek and powerful.

Before being cast out, he had two sets of long, blinding wings that seem to be made of pure light (Light Bearer). During his fall, two of his wings, the ones on the right side, were horribly damaged. They were burned down too the bone as he used those wings to protect himself as he fell. They’re now black and skeletal on that side, the feathers that do remain are charred to the bones. The ones on the left are slightly singed, but for the most part in tact. They still emit their own light, but it’s no longer pulsing in waves of white and gold, but has taken on a dim red glow (Which appears slightly pink)

The third of the four brothers, he has three sets of wings. They’re stunning gold, more coppery near the base but get progressively lighter and brighter as they move out, becoming a more molten gold in the center and white gold at the tips. They’re more extravagant than any of the others, more flashy, showy. His wings are still very much whole and well kept because he is more of a messenger then a fighter, which has served him well in keeping them safe. They’re  grand and majestic, giving him a feeling of regaliality and power. 


Raphael 

The youngest of the four, he has four sets of sleek, streamlined wings, reminiscent of the style and shape of wings of the angels to come after him. Practical for a soldier. They’re deep gray in color, like storm clouds and pulse with ice blue electricity.

Castiel

Wings of a complete and absolute ebony, an unusual color. This plays with the idea that God has a special interest in him, creating him with unique wings unlike any other angel. They’re slightly larger than the average and not quite as sleek. Full and beautiful, but their color and size makes them imposing. They seemed to be constantly shrouded in thick shadows that hangs around them like black fog. When the light hits them just right, they glint electric blue for a moment.

The Ground-Bound Yian Kut-Ku, or: I just took down one of these and, after closely examining its corpse, have some observations to share.

Let’s look at the bone structure first. Yian Kut-Ku’s wings seem to have a basic “frame” formed by the humerus, radius and ulna, metacarpals, and the last phalanx. (For those who don’t know dem bones, that’d be the upper arm, forearm, palm, and finger bones.) You can see the other phalanges (”fingers”) at the top of the wings.

Using the final phalanx as wing support is not something seen–so far as I know–in extant species. However, one extinct group very famously exhibited that trait:

Pterosaurs.

Originally, pterosaurs were believed to have been weak gliders, but evidence now suggests that they were, in fact, capable of true flight. I’ve had Yian Kut-Ku take off into the sky and rob me of a kill enough times to vouch that it, too, is capable of true flight. But I have to wonder how it possibly could, as it appears to be lacking several adaptations.

The first is the propatagium. All vetebrate species capable of flight have a membranous structure in their flying limbs called the patagium, which helps give shape to the wing and therefore makes flight possible. Many flying vertebrates also have a propatagium, which is a membrane that extends from the shoulder to the wrist and forms the front edge of the wing.

In the diagram comparing bone structure, you can see the outline of some propatagia, but here’s another one. The propatagium is the triangular area running from the top of the humerus to the end of the radius and ulna:

Notice how the propatagium gives the wing a more streamlined shape? Rather than being all crooked angles and bony joints, the leading edge of the wing becomes a smooth surface.

My knowledge of physics is too scant to be able to say for sure if that smoother shape contributes to lift or reduces drag, but I can give you a working example. Say you’re driving down the highway and stick your hand out the car window. If you stick your hand out flat, with your thumb tucked in and your palm facing the road, you’ll find you can make it rise or fall by shifting your wrist and tilting your palm; one direction, and it seems to catch the wind and rise on it–another direction, and it seems the wind is only pushing you back. Now imagine trying that, but with your thumb sticking out to create an angled gap. The air won’t flow nearly as well over that uneven surface, and that is why other flying creatures have a propatagium: to smooth out their wing shape.

Yian Kut-Ku has no propatagium, however, and thus has poor wing aerodynamics. While I am no expert in these matters, I’m fairly sure that this monster is probably totally incapable of gliding, and must flap at a near constant rate to achieve and sustain flight.

That constant flapping, however, would rely on powerful wing and breast muscles, and here is where my next concern comes in: its unnervingly flat chest.

The sternum, or breastbone, is an important piece of vertebrate anatomy. In most species, the sternum is flat, vaguely necktie-shaped, and usually made up of several different bones; in humans, it’s made up of three: the manubrium, the body, and the xyphoid process. The sternum serves as an attachment point for the ribs, which helps to form the ribcage and offer better protection to the heart, lungs, and other thoracic squishy bits.

It is also the attachment site of the pectoralis muscles (yes, the pecs), which–despite being located on the chest–are critical for the movement of the shoulder joint. One of the primary functions of the pectoralis major is to adduct the humerus. Hold your arm out to the side, then bring it back against your body; you just used your pectoral muscle there.

As you might well imagine, birds, bats, and other winged creatures have large pectoral muscles, as these would control the flapping of their wings. Well, you’d be right. They do, and these large muscles require a strong attachment point, which they have in the sternum.

This is a human sternum:

This is an avian sternum:

That terrifying ridge rises up at the front of the bird’s chest, but you would never know it because their breast muscles are that thick. A quick way to see if a bird is underweight or unhealthy is actually to feel around its sternum, which is also called the keel due to its shape. If the muscle on either side is level with the keel, the bird is probably at a healthy weight; if the muscle extends beyond the keel, birdy needs a diet, and if the keel juts out above the muscle, the bird should probably gain some weight.

Most of the musculature needed for flight is found in the pectorals; very little of it is actually in the wings themselves. This is why two chicken breasts can feed a family of four, while two chicken wings can feed, like, a child… if they aren’t too hungry. Also because domestic poultry has been selectively bred to have large breast muscle, but the point remains.

By the way, bats also have a keeled sternum, although it’s somewhat less dramatic:

Given that Yian Kut-Ku must flap constantly in order to sustain flight, you would expect it to compensate by having a bulky chest with powerful pectoral muscles attached to a keeled sternum–but it doesn’t. Oklahoma has more exciting topography than Yian Kut-Ku’s chest. My chest has more exciting topography than Yian Kut-Ku’s chest, and in case that reference means nothing to you, let’s just say that I’m 23 and still shop in the junior’s department.

So how, then, does this wonky wyvern take to the skies? Since I don’t like saying “fuck if I know” when I’m in a scientific mood, I’m going to go with my next best answer, which is: its legs.

Yian Kut-Ku appears to have rather powerful legs, which I’ll admit would be a very necessary adaptation. With how foxed up its wings are and how weak its chest is, it’s probably dependent on jumping to get airborne. In-game, we see that this monster is capable of leaping rather high to reposition itself on the field of battle, with its wings giving it a little bit of a boost. We also see that it makes very heavy landings, and that bulky musculature would help absorb the shock of its feet hitting the ground.

It also has a rather long, heavy tail which would very much work against it in flight. If you’re trying to push yourself forward through the air–as a flying creature does–you want there to be as little of you to push as possible, and anything that you have to push should serve a purpose. The tails of bats and pterosaurs are downright vestigial. The tail feathers of bird function like a rudder, helping the bird steer itself in flight. Flying squirrels do have a rather big, bushy tail, but they use it to slow themselves down; additionally, they are not true flyers, bur instead glide–something Yian Kut-Ku is most likely incapable of. Yian Kut-Ku’s tail, then, serves no purpose in flight, and would actually be a hindrance. More on that in a bit.

Most winged monsters in the world of Monster Hunter (or at least, most winged monsters in the world of MH4U up until you take on Gore Magala at the Ancestral Steppe, because 4U is my first game in the series, and that’s where I am right now) will have what I refer to as the “hover phase” in their fight. They flap in place just barely close enough to the ground to be reached with Sword and Shield, and unless there’s a convenient piece of raised terrain nearby, you’ll only be able to chip away at their toes and tail.

Despite having wings and apparently being capable of true flight, Yian Kut-Ku doesn’t have a hover phase in its fights. It spends the fight on the ground, horking up fireballs and pecking at your face and sprinting a few strides only to fall splat on its bizarrely flat chest. This is likely because it simply cannot fly for extended periods of time. Attempting a hover phase would likely exhaust it. Its inefficient, and doubtlessly tiring, flight is probably the reason why we only ever see Yian Kut-Ku take to the air to flee, or to quickly leap back and change its position on the battlefield.

So what conclusion does this lead me to?

Despite having wings and being capable of flight, Yian Kut-Ku is, first and foremost, a terrestrial species.

We see several things in its in-game behavior that suggest this as well. After sustaining enough damage, Yian Kut-Ku begins rooting around underground for Konchu to eat. Its keen sense of hearing would allow it to pinpoint its subterranean prey with ease, and its heavy beak–which would weigh it down tremendously in flight–is perfectly adapted for crushing their solid shells. But there’s one more tell.

When first encountered in an area, this monster is walking around, its wings folded against its body. It walks with slow, heavy struts, its head stretched out in front, its tail bobbing slightly from side to side behind. Then it spots you and rushes in, its neck flailing, its tail swishing in counterpoint. Wait…

That’s what the tail is for.

Yian Kut-Ku’s heavy, muscular tail–a slap from which can send a hunter sprawling–serves as a counter-balance for its long neck and bulky head, and enables it to make better maneuvers on the ground.

Conclusion: Yian Kut-Ku, despite being classified as a Flying Wyvern, is really more of a big ol’ lizard who occasionally flails its way into the sky.

high school kids with wings!!

the girls have their wings glittered and dyed, they brush colored, shimmering powder onto the edges. they interlock their wings with each others’ and take selfies

the boys’ wings are streamlined, metallic grey, strong and thick (some of the boys extend the tips and tickle the girls’ cheeks while others’ wings stand firm and strong). there’s one shy boy whose wings are brown, and he wraps them around his shoulders, close to his face.

one girl with bright white wings that are full of scars, but who smiles every day and tells everyone how much better she’s getting

young couples in the hallway, blushing madly, hiding under their wings like a shelter
