Which component transmits turbine power to the main transmission?

• A. Reduction Gearbox
• B. Accessory Gearbox
• C. Transmission Shaft
• D. Engine Control System

Answer: (C)

In a turbine drive line, the rotating power needs a solid link to the rest of the drivetrain. The transmission shaft is that link—the direct conduit that conveys the turbine’s rotational power to the main transmission, carrying the torque and speed required to drive the load or generator.

The reduction gearbox sits in the power path to adjust speed and torque to suit the main transmission, but the actual component that transmits power onward is the shaft that connects to or from that gearbox toward the main transmission. The accessory gearbox powers auxiliary equipment, and the engine control system handles operation and control, not the primary power transfer.
