What was the result of the Admiralty experiments conducted on the SS Archimedes?
Answer
They demonstrated the superior efficiency of the screw propeller
The rigorous testing carried out by the Admiralty provided the hard, empirical evidence needed to prove that screw propellers were more efficient than paddlewheels. This validation was the turning point that convinced the maritime establishment to transition away from paddlewheels toward the submerged screw technology.
