Hydrodynamic testing of the new DSME 1400 AIP Class Submarine
Under contract with DSME (Daewoo Shipbuilding and Marine Engineering Co. Ltd), SSPA has been testing and simulating the hydrodynamics of the new DSME 1400 AIP Class Submarine. SSPA performed the model testing on a scale model, manufactured and equipped with propeller, active aft control surfaces and forward hydroplanes.
The model testing was performed in two of SSPA facilities, the Towing Tank and MDL (Maritime Dynamics Laboratory), the large wave basin used for evaluation of manoeuvring and seakeeping performance. Our experts have investigated the speed-power performance both at surface and submerged condition. Further SSPA have developed a virtual manoeuvring simulation model of the submarine to test its manoeuvring performance, for example turning radius, yaw-checking and course-changing ability, and depth changes.
SSPA has been involved in hydrodynamic development work for submarines since 1940. During this period, SSPA has been involved in development and testing of all classes of Swedish submarines. The work includes model scale and full-scale tests amounting to a total of well over 600 studies. SSPA has also performed submarine testing for several European and Asian countries e.g. the DSME 1400 Class Diesel-Electric submarine for the export market.
The new DSME 1400 AIP Class Submarine has been targeted to increase underwater sustainability by applying an air-independent propulsion system while keeping its other well-proven subsystems. Therefore, it could be highly cost effective and has a good operation envelope covering littoral and ocean-going missions.

Hydrodynamics for submarines
Developing the hydrodynamics for submarines at SSPA involves a combination of simulation and model testing in order to evaluate the performance of the submarine, such as speed-power requirements, manoeuvring characteristics, cavitation properties and radiated noise from the propellers in deeply submerged, periscope and surface conditions.
Maritime Dynamics Laboratory
The Maritime Dynamics Laboratory (MDL) is a versatile facility for the research and development of seakeeping and manoeuvring behaviour of ships and other structures.
