True or False: The purpose of the swashplate is to convert linear flight control commands into rotational control input for main rotor pitch control of the blades.

• A. True
• B. False

Answer: (A)

The swashplate's primary function in a helicopter is to convert the pilot's linear flight control commands into the necessary rotational inputs that adjust the pitch of the main rotor blades. When the pilot moves the flight controls, the swashplate tilts, which changes the angle of the rotor blades throughout their rotation, allowing for control of lift and direction.

In essence, the swashplate acts as an intermediary between the control inputs (like cyclic and collective commands) and the rotor system. This mechanism allows the helicopter to respond accurately to the pilot's intentions, making it a crucial component of rotorcraft flight dynamics. Therefore, stating that the purpose of the swashplate is to facilitate this conversion of commands into rotational inputs for main rotor pitch control is indeed true.
