Swashplate's function

Swashplate's function

• A. It adjusts the pitch of the main rotor blades
• B. It provides anti-torque
• C. It houses the flight data recorder
• D. It cools the engine

Answer: (D)

Swashplate translates pilot inputs into changes in blade pitch, letting you control both lift and direction. It consists of two parts: a stationary (non-rotating) portion connected to the cockpit controls and a rotating portion attached to the rotor hub. When you move the collective, the stationary part shifts up or down, changing the baseline pitch of all blades at once. When you push the cyclic, the rotating portion tilts with the rotor head, causing each blade to pitch differently as it sweeps around the disc. This differential pitch steers the helicopter, while the uniform pitch change adjusts overall lift. This system is not responsible for anti-torque (that’s the tail rotor or other anti-torque devices), it doesn’t house a flight data recorder, and engine cooling is handled by separate systems.
