Real Time Simulation and Control 3000 Ton Surface Effect Ship with Negative Drag Characteristics in Sea State.

Abstract

The model of a Surface Effect Ship was refined to include simplified propulsion dynamics, negative drag characteristics, sea state effects and an autopilot for speed control. These design modifications were introduced into a real time, man controlled simulation of a 3000 ton Surface Effect Ship (3K-SES) in 5 degrees of freedom (RTS5D) and results were compared with a Data Base Program (DBSIM5D) based on towing tank data scaled up to model the ship. Hardware and Software design changes were incorporated into the RTS5D model to provide a more accurate approximation of real time, a faster computer iteration time, and a broach condition warning if the operator exceeded certain thrust vectoring limits.
