In a Fully Articulated Rotor System, the blades of the rotor can move in multiple ways to effectively respond to various flight forces. This system is designed to allow each rotor blade to independently flap up and down (vertically), move side to side (horizontally), and change its pitch angle.

This flexibility is critical because it enables the rotor blades to adjust to lift demands during flight, particularly when the helicopter is maneuvering or experiencing changes in weight distribution. For instance, during a hover or when climbing, the blades need to adjust their pitch to maintain stable lift. Additionally, as the helicopter changes direction, the blades can flap or move horizontally to counteract the effects of lift vector changes.

Overall, this mobility enhances the helicopter's control and stability, allowing for smoother and more responsive handling in various flight conditions. The design of the Fully Articulated Rotor System is particularly advantageous in managing dynamic loads and ensuring balanced performance across different phases of flight.
