Simulation of Maneuvering Characteristics of a Destroyer Study Ship Using a Modified Nonlinear Model.
Abstract
This report describes an analog computer maneuvering simulation of a destroyer study ship. The mathematical model which is used includes the ship propulsion machinery dynamics and the ship equations of motion. The model couples the ship propulsion dynamics equations with nonlinear maneuvering equations. The power plant representation consists of a simplified mathematical model of a General Electric LM2500 gas turbine engine and is primarily an engine mapping of engine torque versus engine speed using fuel flow rate as a parameter. The simulation is used to accurately predict slow transients in ship speed during maneuvers resulting from slow increases in the fuel flow rate to the gas turbine. (Modified author abstract)
