The classic submarine drive consists of diesel generator units that either transmit the electricity generated directly to the electric drive motors or store it in batteries, in order to also ensure drive during submersed (silent) operation. For these applications, the ability to withstand shocks as well as a very good noise level reduction are major issues. In some cases the usage of special materials can be applied.. In submarines, spacel conditions are often very narrow and therefore the drive units must be kept very compact. This is also true of highly flexible couplings that are built into the electric-motor-driven fixed pitch propeller drive for technical reasons of displacement and noise. For emergency reasons these are fitted with a fail-safe device.
