Abstract
A naval submarine has to cope with different operational modes: sailing at
the surface, just below the surface or fully submerged and at different speeds.
Therefore it needs an appropriate power plant. In this research a first principle
submarine propulsion model has been extended with a Proton Exchange Membrane
Fuel Cell (PEMFC) as Air Independent Power (AIP) system and a Permanent
Magnet Synchronous Machine (PMSM) as propulsion motor. The model
can be used for submarine design. It can determine the dimensions of the power
plant components and the required fuels to perform a certain mission. Eight
different configurations have been simulated. From the simulation results can be
decided which concept is most profitable in terms of volume, mass and efficiency.
