A rotor system is a crucial component of aircraft, particularly in helicopters. It consists of rotating blades that generate lift, allowing the aircraft to ascend, descend, and maneuver in the air. The rotor system can be classified into different types, such as single-rotor and tandem-rotor configurations, each serving specific flight needs. The rotor system operates by creating differences in air pressure above and below the blades. As the blades spin, they push air downwards, resulting in an upward lift force. This mechanism is essential for the flight capabilities of rotorcraft and is fundamental to their design and operation.
