Influence of adjustment of gas turbine controller on ship propulsion system behaviour in rough sea conditions

摘要

The paper presents a dynamic model of ship propulsion system, elaborated with the use of the stiff finite element method. The ship propulsion system consisted of two gas turbines driving - through toothed gear - controllable pitch propeller, was used to analysis. In the simulation model disturbances both from setting of propeller shaft's angular speed and of propeller pitch during the system's operation in rough sea conditions, were accounted for.
