Innovation at 100

Air travel, spaceflight, robotic solar-system missions: science fiction to those alive at the turn of the 20th century became science fact to those living in the 21st. 

America’s aerospace future has been literally made at our Langley Research Center by the best and brightest the country can offer. Here are some of the many highlights from a century of ingenuity and invention.

Making the Modern Airplane

In times of peace and war, Langley helped to create a better airplane, including unique wing shapes, sturdier structures, the first engine cowlings, and drag cleanup that enabled the Allies to win World War II.

In 1938 Langley mounted the navy’s Brewster XF2A-1 Buffalo in the Full-Scale Tunnel for drag reduction studies.

Wind Goes to Work

Langley broke new ground in aeronautical research with a suite of first-of-their-kind wind tunnels that led to numerous advances in commercial, military and vertical flight, such as helicopters and other rotorcraft.

Aeronautics Breakthroughs

Aviation Hall of Famer Richard Whitcomb’s area rule made practical jet flight a reality and, thanks to his development of winglets and the supercritical wing, enabled jets to save fuel and fly more efficiently.

Tracking Earth from Aloft

Development by Langley of a variety of satellite-borne instrumentation has enabled real-time monitoring of planet-wide atmospheric chemistry, air quality, upper-atmosphere ozone concentrations, the effects of clouds and air-suspended particles on climate, and other conditions affecting Earth’s biosphere.

Crucial Shuttle Contributions

Among a number of vital contributions to the creation of the U.S. fleet of space shuttles, Langley developed preliminary shuttle designs and conducted 60,000 hours of wind tunnel tests to analyze aerodynamic forces affecting shuttle launch, flight and landing.

Safer Space Sojourns

Protecting astronauts from harm is the aim of Langley’s work on the Orion Launch Abort System, while its work on materials and structures for lightweight and affordable space transportation and habitation will keep future space travelers safe.

Unmasking the Red Planet

Beginning with its leadership role in Project Viking, Langley has helped to unmask Martian mysteries with a to-date involvement in seven Mars missions, with participation in more likely to come.

Going Green

Helping to create environmentally benign aeronautical technologies has been a focus of Langley research, including concepts to reduce drag, weight, fuel consumption, emissions, and lessen noise.

Intrepid Inventors

With a history developing next-generation composite structures and components, Langley innovators continue to garner awards for a variety of aerospace inventions with a wide array of terrestrial applications.

Hartwin, 13

((Finally getting to these!))

               Harry watched the whiskey as he swirled it in his glass, the fire crackling off to his side. Beyond the front window snow fell softly, gathering on the windowsill in thick, almost animated flakes. It was another Christmas. Another year alone. Another year beside his fire, drinking his way through a bottle of Royal Salute 38-year-old whisky. He supposed it could be considered a tradition. Maybe not in typical sense, since traditions generally encompassed family and friends, but Harry had done it for the last decade.

               There had been a time when he hadn’t been alone on Christmas. When he’d fooled himself into believing that he could have a life outside of Kingsman. When he dared to try and find love. But that idea had been extinguished as quickly as it had caught fire.

               Harry took a long sip from his glass, savoring the richness of the malt, and allowed himself to relax into his chair. He wouldn’t necessarily say he was happy. Content, perhaps.

               The log in the fire popped. Harry sighed and watched the fire as it sizzled and danced. No, content wasn’t the word either. A loneliness ached behind his ribs. It had been there for a long time, a quiet hum that had been easily ignored, but now persistently called to him. It had grown loud and constant ever since a certain green-eyed agent had waltzed into his life.

               A single present rested on the coffee table, a reminder of Harry’s failures. He’d bought it for Eggsy and planned to give it to him earlier that day, but at the last minute had decided against it. He didn’t want to muddy their already complex relationship.

               A knock at the door roused Harry from his ruminations. He set his glass down and answered the door.

               Harry gasped. “Eggsy.”

               Eggsy stood on his stoop, dusted with snow, his nose and cheeks pink from the cold. He smiled toothily at Harry and held out a beautifully wrapped package. “Merry Christmas Harry.”

               “What are you doing here?” Harry asked. “Shouldn’t you be with your family?”

               “I’ll be seeing her tomorrow.” Eggsy said. “Now, mind if I come in? It’s a bit cold, yeah?”

               Harry blinked, startled. Where were his manners? He stepped aside to let Eggsy through. Eggsy shook off the snow from his jacket and stomped his boots before stepping in with a contented sigh.

               “Let me take your coat,” Harry said, already stripping it from Eggsy.

               “Thanks, bruv,” Eggsy said. “Snow started falling on the way here.”

               “Would you like a cup of tea?” Harry offered. “Or I just opened a lovely bottle of whisky.”

               “Latter will do.” Eggsy said, following Harry into his living room.

               The process of pouring Eggsy’s drink allowed Harry to gather his bearings. By the time he handed the crystal tumbler to him, Harry felt more like himself again.

               “I didn’t realize you’d be showing up, I would have something prepared.”

               “You didn’t really think I’d let you spend Christmas alone, did you?”

           Despite his best attempt to still it, Harry’s heart gave a flutter. Not sure how to follow the statement, other than an obvious, ‘well of course I did, you have family to be with’, Harry snatched up his gift and held it out for Eggsy. “This is for you.”

           Eggsy blinked. A grin spread across his face and he accepted the long package. “Can I open it?”

           “Of course,” Harry said, even though he immediately wanted to snatch the present back, not sure if the gift was overtly extravagant or not.

           Eggsy set his own present down and opened the one Harry gave him. He tore into it like a child, shredding paper and tossing the bow. Beneath the glossy wrapping was a leather jewelry box, and nestled inside, a sleek custom watch Harry had Merlin make.

           “Harry…” Eggsy whispered, removing the watch. It was black straps and a black face with a silver frame. There were no numbers, just a single diamond chip for the twelve o’clock, and thin silver hands the tick away.

           A slow giddiness pooled in Harry’s stomach as he watched Eggsy fiddle with the watch and slip it on. He reached out, murmuring a soft ‘may I’ when Eggsy struggled to secure the watch, and carefully wrapped it around Eggsy’s slender wrist.

           “It’s has all the standard features of a Kingsman watch, but with a few extras I had Merlin add in. Just some ideas I had seen you tooling around with.”

           Eggsy snapped his head up. “You don’t mean…”

           Harry smiled. “I do. Not only can it shoot amnesia and kill darts, but it can release a tracker, as well as a supersonic sound to stun enemies.”

           “Fuck, that’s sick,” Eggsy whispered. He flung his arms around Harry, causing him to stumble back a pace, and hugged tight. Into the curve of Harry’s neck, Eggsy mumbled, “Thank you.”

           Harry allowed himself the small concession of returning the hug, holding Eggsy close, even for only a moment.

           Eggsy pulled back all too soon, and Harry immediately missed the warmth of his body.

           “Open yours,” Eggsy ordered and held the box out. It was small, perhaps the size of a ring box.

           Harry took his time removing the bow and peeling back the tape. The corners of his mouth twitched as he watched out of his peripheral as Eggsy impatiently stood beside him, bouncing from foot to foot. He peeled the paper back, revealing a ring box. Harry raised an eyebrow at Eggsy, who just smiled in return, and opened the box.

           He didn’t know what he expected, but it certainly wasn’t a piece of herbs tied with a red ribbon. “I don’t understand,” Harry said, looking at Eggsy.

           Eggsy picked up the herb and held it above his head. “It’s mistletoe,” he stated.

           Harry’s breath caught in his throat. He searched Eggsy’s face, who stared back at him with such wide and clear eyes, every ounce of emotion he seemed to possess visible in their verdant depths.

           “I didn’t know what to get you,” Eggsy said, cheeks brightening like he’d just stepped outside again. “So, I thought I’d give you… me.”

           When Harry didn’t respond—his brain still not quiet processing what was happening—Eggsy started to lower the mistletoe with a nervous laugh. “It’s just—”

           Harry swept him into his arms and kissed him. Eggsy melted into his embrace, his arms coming to wrap loosely around Harry’s neck.

           Harry parted only long enough to whisper, “It’s all I could ever want.”

           Eggsy smiled and pressed their foreheads together. “Merry Christmas Harry.”

           “Merry Christmas, my darling boy.”

The Trumpet Pokemon

Type: Rock/Steel

Ability: Vocalist*

Height: 2′11″/0.9m

Weight: 69.4lbs/31.5kg

Evolutionary Chain: Restore from Nasal Fossil -> Ensaur -> [lvl. 30] -> Paracoustic

This little herbivore was apparently very social; Fossil beds have shown entire fields lined with their nests. When together they sing by taking in air, then expelling it through their trumpet-like crests. No two Ensaur sound the same, which might be how their parents can pick them out of a herd of 200 no sweat.

Notable Moves: Disarming Voice, Echoed Voice, Screech, Metal Sound, Supersonic, Rock Tomb, Metal Burst, Iron Tail


The Brass Pokemon

Type: Rock/Steel

Ability: Vocalist*

Height: 5′03″/1.6m

Weight: 226.0lbs/102.5kg

Evolutionary Chain: Restore from Nasal Fossil -> Ensaur -> [lvl. 30] -> Paracoustic

They roamed in massive herds millions of years ago. Their intricate curved sinuses allowed for much more complex- and much louder- songs. One Paracoustic let loose a roar recorded at 190 decibels- more than enough to cause permanent ear damage. They probably used this volume to defend themselves from Tyrantrum, whom loved to dine on them.

Notable Moves: Boomburst, Hyper Voice, Uproar, Bug Buzz, Screech, Metal Burst, Rock Slide, Iron Head

*Vocalist: The power of Damaging, Sound-based moves is boosted by 50%

Oops I’m on a roll, look at that. If anyone has ideas for other fossils, I’m not saying pitch ‘em, but pitch ‘em.

The First Supersonic Flight

Robert Goddard flew his first liquid fueled rocket in March of 1926, a flight that last only seconds and traveled less than 200 feet.  Less than a decade later, Goddard was testing the A-series rockets and achieving supersonic flight.  His technological innovations were coming so fast that there were not even words to describe them.  The word supersonic, for example, entered English as an adjective in 1919 but meant out of the range of human hearing.  The word came from the Latin prefix super- meaning above, over or beyond and the Latin sonus meaning sound.  By 1934 scientists needed a word to describe something that traveled or propagated faster than the sound waves themselves, and stuck with supersonic.  On March 28, 1935, Goddard tested what he called an A-Series rocket, often with luminaries and benefactors present, including Charles Lindberg and Harry Guggenheim.  The rocket traveled almost a mile in the air with an average speed of almost 550 miles per hour, breaking the sound barrier on the way.  The first supersonic flight was 80 years ago today!
