31. Propellers
The Titanic II will have propellers mounted in Azipods or pods that can turn on a vertical and azimuthal axis for steering. The original Titanic had three propellers. Two would not be enough to transmit the power at the engine’s nominal speed, and the centerline propeller was driven by a Parsons low-pressure turbine using the low-pressure steam after it went through the reciprocating engines that drove the two outboard propellers.
The two outer propellers had three blades, and the centerline propeller had four. Essentially, the designers tried to combine the two types of propulsion engines thermodynamically and hydrodynamically through the use of three- and four-bladed propellers.
