Which main rotor system component serves as the mounting point for hydraulic dampers, pitch control rods, and anti-flapping assemblies?

• A. Droop Stops
• B. Swashplate Assembly
• C. Main Rotor Hub
• D. Anti-Flap Assemblies

Answer: (C)

The main rotor hub is the central mounting point where all blade-related control and stabilization components come together. Hydraulic dampers are attached to the hub to absorb blade flapping, and the pitch control rods (the links that carry pilot or swashplate inputs to each blade) connect through the hub to move the blade grips. Anti-flapping assemblies are also mounted on the hub to constrain up-and-down blade motion. Droop stops exist at the blade root to limit droop at low rotor speed, and the swashplate provides the input that sets blade pitch but does not serve as the hub for these mounting points.
