Submarine Dynamic Simulation

The submarine dynamic simulation capability within Paramarine enables the designer to perform dynamic simulations of submarine manoeuvres. This module takes the basic geometric shape of the submarine and generates a set of linear derivatives. These are then used in conjunction with an unclassified nonlinear coefficient set to provide input parameters for a full nonlinear 6 DoF submarine simulation.

Alternatively a coefficient set from model experiements may be used directly, if available.

The simulation is based on the W.S. Atkins’ S4 submarine dynamic simulator, and provides the user with the ability to simulate a wide range of open-loop manoeuvres, and presents the results in several graphical formats.

Using the S4 facility enables the designer to very quickly gauge the main submarine dynamic performance indicators such as tactical diameter, advance and transfer in the lateral plane, and overshoots and depth excursions in the vertical plane.

Of particular note is the ability to easily create manoeuvring limitation diagrams (MLDs) to aid the user in the very early stages of the submarine concept design.
