ELI5: Explain Like I'm 5

X-53 Active Aeroelastic Wing

The x-53 active aeroelastic wing is like a really cool airplane that can change its shape while it's flying! Normally, airplane wings stay the same shape all the time, but with the x-53, the wings can kind of bend and move to make the plane fly better.

Here's how it works: when the plane is flying, there are a bunch of sensors and computers that are always watching the wings to make sure they're doing okay. If the sensors notice that the wings are bending too much, the computers can tell some special parts in the wings to push and pull on the metal and make them stiffen up. That way, the wings don't bend too much and the plane can fly more smoothly.

But that's not all! The x-53 also has some wiggly bits near the back of the wings, called flaps, that help the plane turn and go up and down. The computers can move these flaps around too to help the plane stay balanced and fly better.

All of this cool stuff makes the x-53 a really special plane that can do things other planes can't. So next time you see a plane in the sky, maybe you can imagine it wiggling around like the x-53, even if it looks pretty still from far away!
