METHOD FOR LOW-SOUND-EMISSION ACCELERATION OF A PROPELLER DRIVEN WATERCRAFT

摘要

The method for low-sound-emission acceleration of a propeller-driven watercraft, in particular a submarine, is characterized in that in a first phase acceleration states are determined at which a 5 predetermined sound emission is just being exceeded, after which in a second phase acceleration states are determined at which the predetermined sound emission is not being exceeded, with the propeller(s) subsequently being actuated in such a way as not to exceed the acceleration states determined in the second phase.
