- Ethan became fascinated by this kind of airplane design when he saw a video of NASA's Prand(I-D aircraft gliding gracefully through the air without a tall "Tjust thought that was really cool"says Ethan. He's a seniorat Arcodia High School in Callfornia, Ethan bulds model airplanes for fun. He wondered if he could find a simpler way to achieve the same tailless flight. "Essentially what I did was just trial and error."Ethan says. Using a computer model of an airplane wing, he tweaked the angle of twist along the wing until it could achieve tailless flight. Usually, such a wing "requires a continuous distribution of wing twist;Ethan says. But he could achieve a similar effect with wings that had just a few sections of twist. "It's super easy to make." In his garage, Ethan built model airplanes using foam and packing tape to test his design "Seeing the plane in the air. that was pretty cool;Ethan says. "It just flew really, really well." Lighter, more efficient planes could open the door to other air travel innovations. "It's been a long-term goal of mine to build a solar plane that can fly through the day powered by solar panels on its wings;Ethan says. "It is absolutely possible for a really efficient plane." To other teens who have big engineering ideas they want to explore, Ethan has one word: persistence. "Don'ever give up," he says. Even when some machinery feels impossible to understand, it helps to remember that the world's greatest inventors were only human, too. "Also, just make sure you love whatever you do.Ethan adds. "Tha'll make pursuing everything toleases PAUSEAND REFLECT: What commonalities do these three inventors share in their approaches to innovation?
