Abstrakt:

The article presents the impact of damage to the centrifugal compressor of the P&W 206B2 turbine engine, built in the EC-135p2 helicopters EC-135p2. The damages are caused by sucking the foreign bodies to the inlet, what results in the changes of exploitation parameters of the engine and thermodynamic parameters of operating medium. On the basis of the parameters, measured during engine operation, such as: rotation speed of the rotor of the compressor – n1, the rotation speed of the turbine shaft of the drive – n2, the gas temperature at the outlet of the turbine driving of the compressor – T4.2, and the fuel flow rate – ��̇ p, distributions of these parameters in various cross – sections of the engine were determined and compared. Then, on their basis, the CFD analysis of air flows in new and damaged compressors was performed.
