GAS TURBINE SIMULATION TECHNIQUE FOR SHIP PROPULSION DYNAMICS AND CONTROL STUDIES

A gas-turbine simulation technique for ship propulsion dynamics and control studies is discussed. A review of existing generalized gas-turbine simulations indicates previous efforts have concentrated on a aircraft engine configurations and few existing simulations have the capability for calculating transient performance. Marine engines of current interest are free-power-turbine gas-turbines having either single-spool or dual-spool gas generators. The mathematical techniques used to model the compressor, burner, turbine, engine load and fuel control are summarized. A modified Newton-Raphson convergence technqiue is used for solution convergence. Component maps, design constants, and fuel control characteristics for General Electric's LM2500 marine gas turbine are used to demonstrate this technique. Typical results are shown for steady-state and transient performance calculations.
