Después de los winglets llegan los finlets para ahorrar otro uno por ciento en el consumo de combustible de los aviones
Cada gota cuenta, en especial teniendo en cuenta que una aeronave comercial está todo el tiempo posible volando.

To help answer this question I drew a diagram of Mackenzie's tail. Her dorsal fins have rays which are pointed which you'd have to be careful around. Her four finlets are semi ridged but safe to touch. Her tail fin is actually quite soft and pleasant to touch.

Sorry for not seeing this sooner.

So I knew what Sharkets were. I knew what split wing scimitar winglets were. I knew what blended wingtips were.

Now enter the matrix... with Finlets.

These finlets are a product of Vortex Control Technologies. They already have a number of contracts with airlines for retrofitting their finlets on 737s.

Throws my TFA Time Travel AU into the ether here.
Contains #MegOP.
Inspired by this fan animation (www.youtube.com/watch?v=9VYP...), which then snowballed into its own AU.
For anyone curious about the lore/story, I will add a link to the post I made on tumblr about it.

A colored sketch of a younger version of Transformers: Animated Megatron, otherwise D16. His armor is more blocky, while his shoulder pauldrons are shorter too. The red parts from his design are a darker shade of blue. There are also strips of caution tape littering his body in symmetrical fashion, on his forehead, two on his chest, one each for his shoulder pauldrons, one each for his lower arms, and one each for his knees. His fusion cannon also has a drilling device strapped onto it, with wiring connecting the two machines. A colored bust sketch of Transformers: Animated Optimus Prime. He shows different types of damage on his head and shoulders, some were treated with sheets of metal. He looks tired under the eyes, but wears a small smile. On the upper left is a speech bubble and a small head of D16 happily yelling "Orion!" to refer to Optimus. Waist-Up sketch of Optimus and D16. More of Optimus' damage can be seen, which also shows that his design isn't the one from the show, but more the power suit one from the comics. He wears a grim expression on his face, and his audio receptors/finlets are going slightly back with tension. D16 stands next to Optimus with an unbothered smile on his face. Both of them have thought bubbles over them, with Optimus' being the bigger one. Optimus has the Wikipedia article for "Killing baby Hitler" in his thought bubble, while D16 has the meme image of the propeller hat dog holding a lollipop in his. A sketch colored in different shades of purple depicting different versions of D16 and Megatron. D16 is slightly turned to the left with his body, while happily facing the viewer with an open-mouthed smile and closed eyes. He is the lightest in color and shines like a soft light. Megatron, as a young gladiator, stands behind him, a somewhat angry expression on his face. His whole body is facing the viewer, and his eyes are open. Megatron, as he is seen in the show, has his body turned slightly to the right away from the viewer. His face is in a 3/4th profile, but his eyes are on the viewer. He is the one who is cast the most in shadow. His expression is blank and unbothered. Above the three figures is text in a pixelated font saying: "Do I look like him?"

i think the nile bichir's dorsal finlets make its silhouette kind of look like the way i drew both gators and dragons as a child (badly). like they kind of look like they could walk if they wanted. and apparently they have Smooth Lungs ?

Caved to my lewd thoughts and decided I finally wanted a hyper OC to call my own. Adopted this fine fellow from the great @crescent-blue-zero.bsky.social

"Nho Vahdy" will probably act as my main OC moving forward. Who knows, maybe one day you'll see him humping some gal's boobs. #HyperSky #HyperArt
A colored and sketchy naked reference pic of a cartoony snow-white squid boy. The young man has a slim upper body, with broad, thick hips, and similarly thick thighs situated beneath them. These thighs are each slightly wider than his torso, making him come across as VERY bottom heavy and pear shaped. A few, small finlets stick out of the sides of his legs, and a hyper penis almost as long and thick as his legs themselves dangles between them. Barely visible, the cock's blue tip peeks out from within a wrapping of near featureless white foreskin. From the top of his actual head, a squid's body protrudes out, sort of looking like a hat on him. A couple of short, thick rounded tentacles protrude from the base of said hat, giving him the appearance of having something akin to stylized dreadlocks. Blue markings exist at the ends of his tentacle hair, as well as his hands and pointed feet, their shape resembling messy splashes of water painted onto his limbs. His eyes are a traffic-light yellow, no pupils, and are in a slanted diamond shape on his circular, smiling face. The squid from the previous picture, now leaning over a nondescript building's indoor railing and excitedly pointing at something off-camera. His giant cock is dangling between the posts of the railing and over the edge of the balcony, even BIGGER than previously depicted by a good foot-and-a-half to two feet. His ballsack is also now visible, dragging languidly on the floor behind him as he stands up on one leg to get more vantage over the railing. His lifted leg, though obscured from view, is squishing up slightly against his bulbous ass, giving his already large buttocks an even more round and pert shape than it might've normally had.

Delta rüstet 240 Boeing 737-800 und -900 mit Finlets aus
Das Skyteam-Mitglied aus den USA wird ihre gesamte Flotte von Boeing 737-800 und 737-900 ER mit sogenannten Finlets des Unternehmens Vortex Control Technologies ausrüsten. Insgesamt sollen 240 Flugzeuge die aerodynamischen Anbauten erhalten. Die Entscheidung fiel gemäß Delta Air Lines nach einer umfangreichen Erprobung, die Flugtests, Betriebsanalysen und aerodynamische Untersuchungen umfasste. Finlets werden am hinteren Rumpf installiert und verbessern die Luftströmung. Dadurch sinkt der Luftwiderstand, was den Treibstoffverbrauch und die Kohlendioxid-Emissionen reduziert.

MC-130J Tests Aerodynamic ‘Finlets’ to Reduce Drag, Fuel Costs
An MC-130J special operations aircraft took off from Eglin Air Force Base, Fla., earlier this month with tiny aluminum fins mounted to its rear door and on either side of its tail fin—the latest step by the Air Force to squeeze fuel efficiency out of its fleet. The post MC-130J Tests Aerodynamic ‘Finlets’ to Reduce Drag, Fuel Costs appeared first on Air & Space Forces Magazine.
