Re: [Electric Boats] Why gear reduction?

 

true enough.  I guess the only way to estimate propellor efficiency is to infer it by calculating all the other efficiencies, then looking at total watts in vs watts out and subtracting the known quantities, leaving what's left to be prop efficiency plus other unknowns.  But we should be able to assume that the propellor efficiency is the lion's share of that.


Thanks for the correction.
