Which component does the power turbine indirectly affect within the TH-73?

• A. Main rotor system
• B. Tail rotor system
• C. Fuel injection system
• D. Cooling system

Answer: (A)

The main rotor system is directly influenced by the power turbine in the TH-73. The power turbine converts the energy produced by the combustion process into mechanical energy, which in turn drives the main rotor. This interaction is crucial because the helicopter's ability to lift and maneuver relies heavily on the rotation of the main rotor blades, which are powered by the speed and torque produced by the power turbine. The linkage to the main rotor is established through the transmission system, which transmits the power generated by the turbine to the main rotor assembly. Effective functioning of the power turbine ensures that the main rotor receives appropriate power and speed needed for optimal performance, making the main rotor system the component that is indirectly affected by the power turbine. In contrast, while the tail rotor system, fuel injection system, and cooling system may have operational connections to the overall performance of the helicopter, their functionality does not hinge directly on the mechanical output of the power turbine in the same way that the main rotor system does.
