Question 46Steam Plants - QMED70% to pass
According to the illustrated cross-compounded main propulsion turbine set, where are the astern elements located? Illustration SE-0016
AI Explanation
The correct answer is D) Forward end of the low pressure turbine.
The astern elements in a cross-compounded main propulsion turbine set are located at the forward end of the low pressure turbine. This is because the astern elements are responsible for providing reverse thrust, and by placing them at the forward end of the low pressure turbine, they can efficiently generate the necessary reverse power.
The other answer choices are incorrect because the high pressure turbine is not involved in generating astern thrust, and the aft end of the turbines would not be the appropriate location for the astern elements.
