Question 164General Subjects - 1st Asst/Chief70% to pass
Of the following propulsion modes, which one would operate with a geared-drive featuring a single reduction?
AI Explanation
The correct answer is B) Medium speed diesel.
Medium speed diesel engines typically operate with a geared-drive featuring a single reduction. This configuration allows the diesel engine to run at its optimal speed while the propeller operates at a lower speed, improving efficiency. In contrast, slow speed diesel engines often have a direct-drive arrangement without a gear reduction, while steam turbines and gas turbines use different propulsion systems that do not feature a single reduction gearbox.
