Question 4Gas Turbine - 1st Asst/Chief70% to pass
In the operation of a marine propulsion gas turbine, kinetic and thermal energy required to drive the main propeller shaft are extracted by which of the following?
AI Explanation
The correct answer is A) Power turbine.
In a marine gas turbine propulsion system, the kinetic and thermal energy required to drive the main propeller shaft are extracted by the power turbine. The power turbine is the main component that converts the energy from the hot, high-pressure exhaust gases into mechanical power to turn the propeller shaft.
The other options are incorrect because: B) COWL diffuser is responsible for diffusing the air flow from the compressor, C) Multi-stage compressor compresses the air intake, and D) Variable Stator Vane actuators control the angle of the stator vanes to optimize the air flow through the compressor.
