Unequal rotor lift distribution

Have you ever seen a toy helicopter with two spinning propellers on top? Well, a real helicopter also has two spinning propellers called rotors, but they are much bigger and stronger.

When the rotors spin around, they create a force called lift that helps the helicopter stay in the air. But sometimes, the lift is stronger on one side of the helicopter than the other, which is called unequal rotor lift distribution.

Let's imagine you are holding a toy helicopter with both hands, and you start spinning the rotors. If you spin one rotor faster than the other, the helicopter will start tilting to one side. That's because the lift is stronger on the side with the faster rotor, and the helicopter will be pulled in that direction.

In a real helicopter, unequal rotor lift distribution can happen if the rotor blades are damaged or not adjusted properly. This can make the helicopter harder to control and even dangerous to fly.

Pilots have to be very careful and pay attention to the rotor lift distribution to make sure the helicopter stays balanced and stable. It's like driving a car – you have to make sure the wheels are all going the same speed, or you might swerve off the road!
