This paper is devoted to analyse of the performance of a turboshaft engine at various off-design conditions. In identification of the component maps of the engine, performance data elaborated by engine manufacturer was used. The prediction of some important parameters of the engine like mass flow rate of air, pressure ratio of compressor, output shaft power, total temperature of gas at power turbine inlet, fuel flow and specific fuel consumption are made at various equilibrium running point and off-design conditions. The results of computational analysis for course working line are compared with measured parameters obtained from experimental tests of PZL-10W2 turboshaft engine.
