Rotor blade flutter is one of the main influencing factors affecting the safe operation of gas turbine compressor.By using the one-way coupling and two-way coupling method
flutter analysis for the first stage rotor blade in a heavy duty gas turbine compressor is accomplished under different conditions.The results show that
under the design condition
the flow hinders the rotor blade vibration
and the first stage rotor blade of the compressor remains stable.The blade flutter occurs under the near stall condition and the flutter frequency is 112.00 Hz.The one-way coupling and two-way coupling methods can both be applied to analyze the rotor blade flutter.The maximum stress value calculated by the two-way coupling method is higher than that by the one-way coupling method
