In the process of operation of naval gas turbine is necessary to know their parameters depending on their load, resulting from the swimming speed of the ship. The above equation is the operating characteristics. Classify them into: static (rotating, full-load, collaboration engine power with the receiver), dynamic (starting, acceleration and deceleration) and the universal. The paper presents the results of preliminary tests concern develop rotating characteristics an object of investigations work in the stationary states. The object of investigations was the main propulsion engines frigate type Oliver Hazard Perry which is supplied with the Polish Navy. The propulsion system consists of two naval gas turbine LM2500, reduction gear, shaft line and adjustable screw propeller. Preliminary tests were carried out during the departure of the ship to sea in a marine power plant. The measurements recorded in the engine load range from the minimum to the nominal used to develop characteristics. During the test engines have been simultaneous and the balanced load. In order to allow comparison of operating characteristics of engines tested, as well as references to the various weather conditions, the results of measurements on which it was set, brought to so-called "regulated by weather conditions". For these characteristics, using statistical analysis, were determined dependence of approximation. The received relationships can be used on need of technical diagnostics as well as the more far investigations of considered object of investigations.
