Question 550Steam Plants - Assistant Engineer

The correct answer is B) Between the rotors and high-speed pinions of the high-pressure and low-pressure turbines. In a modern geared turbine main propulsion unit, the part shown in the illustration SE-0001 would be located between the rotors and high-speed pinions of the high-pressure and low-pressure turbines. This is the typical placement of the coupling or flexible connection that allows the transfer of power from the turbine rotors to the high-speed pinion gears. The other options are incorrect because they do not accurately describe the location of this component within the geared turbine system. The coupling is not located between the bull gear and line shaft, nor is it situated between the first reduction gears and high-speed pinions.
