Characteristics Determination of LM-2500 Naval Gas Turbine in Aspect of Energy Modeling and Simulations

Abstract:

The paper presents the results of study concerning the determination of operating characteristics of the examined engine in steady states. The study concerned main propulsion engines of an Oliver Hazard Perry class frigate operated by the Polish Navy. The studies were conducted in the ship's engine room when the ship was at sea. Operating characteristics were determined on the basis of the measurements recorded over the entire load range of the engine, from minimum to rated load. During the studies, the load of both engines of the ship was simultaneous and balanced. In order to facilitate the comparison of the operating characteristics of the tested engines, as well as to make a reference to various weather conditions, the data obtained was reduced to standard reference state. For the aforementioned characteristics approximation relations were determined using statistical analysis. The relations obtained may be utilized in energy modeling and simulations, as well as technical diagnostics concerning this kind of engines.
