This time I'm going to explain a bit about the Titanic's massive propellers!!!
The top three pictures you see are what the propellers look like today. They haven't changed much from the day when they were constructed, bronze does not rust like steel.
Steam ships have propellers to drive them through the icy, choppy, or calm seas.
The Titanic had three huge propellers, two three bladed ones, measuring 23ft & 6in, weighing in at 38 tons of solid bronze metal. The center propeller was slightly smaller than her two sisters, the middle one came in at 16ft, & 6in, also weighing in at 17 tons of solid bronze metal.
Each of these propellers were driven by a separate engine, the two side propellers had a reciprocating, four cylinder, triple expansion, direct acting, inverted engines, creating 30,000 hp.
The center propeller was driven by a completely separate engine. The leftover steam from the reciprocating engines went to a third, low pressure, Parsons turbine engine, creating 16,000 hp.
Just by looking here we see the immense proportions Titanic's propellers were given.
If you notice, the men in these pictures seem over-awed at the size of these massive propellers. They completely dwarf the men that built them.
As I will explain at a later time, these propellers would play a major role the night of April 14, 1912...
I did some research, and come to find out, the propellers on the Titanic are bigger than the propellers on the biggest cruise ship to this day.
You really never see the propellers on big ships like this when they are in service, but without them, you're not going anywhere. They play a vital role in the ship getting from point A. to point B.
The propellers on a ship are like the wheels and tires on a car!!!
Well that's all for now, but that's just the "tip of the iceberg" as they say.
