Which of the following are basic components of a helicopter rotor system?

The basic components of a helicopter rotor system play a critical role in the aircraft's functionality and performance. The rotor hub, rotor blades, and control mechanisms are essential elements of the rotor system.

The rotor hub is the central part that connects the rotor blades to the helicopter and allows for their collective and cyclic pitch changes, enabling the helicopter to lift, descend, and perform maneuvers. The rotor blades are the large, aerodynamic structures that generate lift when they spin, crucial for the helicopter's ability to fly. Control mechanisms include the various systems that allow the pilot to control the pitch of the rotor blades, which directly influences the flight path and responsiveness of the helicopter.

Understanding these components is vital for any aircrewman or technician as they directly impact the helicopter's performance, stability, and overall flight characteristics. Knowing how these parts work together gives insight into helicopter operation and maintenance, which is essential for safety and efficiency in flight operations.
