Which component is described as transferring movement from the rotating swashplate to the main rotor blades?

• A. Tail Rotor
• B. Pitch Control Rods
• C. Swashplate Assembly
• D. Main Rotor Hub

Answer: (B)

Pitch control rods are the link that transfers movement from the rotating swashplate to the rotor blades. The swashplate changes pitch based on pilot input, and the pitch control rods connect from the swashplate to each blade’s pitch horn, pushing or pulling to raise or lower blade pitch as the rotor turns. This is how cyclic and collective inputs produce the changing lift and blade angle during flight. The tail rotor handles anti-torque, the swashplate assembly contains the rotating and stationary parts but doesn’t by itself move the blades, and the main rotor hub is where the blades attach rather than the mechanism that transmits swashplate motion to pitch.
