Variable-sweep wing

A variable-sweep wing is like a bird's wing that can change its shape. Imagine a bird stretching and bending its wings to adjust to different wind conditions. Similarly, an airplane with a variable-sweep wing can change the angle of its wings, almost like they can move backward and forward. This can make the airplane more efficient, which means it can fly longer and faster while using less fuel. For example, if the airplane wants to travel really fast, it can sweep its wings backward. But if it needs to fly more slowly or take off and land, it can sweep its wings forward. Just like how a bird can use different wing positions to do different things like glide or climb, an airplane with a variable-sweep wing can adjust its wings to do different things too!
