This paper describes an analog computer maneuvering simulation of a destroyer study ship. The mathematical model 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. The advantage of the modified model presented in this paper over those not including propulsion dynamics is that it permits simulations of the effects of maneuvering on the propulsion plant.
