What is the role of driveshafts in the rotor system?

The role of driveshafts in the rotor system is indeed to connect all gearboxes and the engine to the transmission systems. Driveshafts serve a critical function in transferring power from the engine through various gearboxes to the rotor system, facilitating the rotation necessary for flight. This connection ensures that the main rotor and tail rotor receive the appropriate power output for optimal operation.

In an aircraft, particularly helicopters, the efficient transfer of power through the driveshaft is essential for performance, control, and stability. Each component linked by the driveshaft interacts to maintain a functional rotor system, which is pivotal for the aircraft's ability to take off, hover, and maneuver.
