Proprotor
Okay kiddo, have you ever seen a helicopter before? You know, those cool machines that can fly in the air like a bird? Well, helicopters have something called a rotor, which is like a big spinning propellor that helps it move through the air.
Now, some smart people wanted to find a way to make helicopters even better, so they came up with something called a proprotor. A proprotor is like a combination of a regular rotor and a propellor. It can spin in one direction like a rotor to help the helicopter move up and down, but it can also twist to spin like a propellor to help the helicopter move forward.
Think of it like a toy that can change shape. Sometimes it's like a spinning top, and sometimes it's like a fan that blows air forward. That's what a proprotor is for a helicopter - a cool new invention that makes it even more amazing than before!
