Flutter calculations of 1st and 2nd compressor stages are conducted for different engine regimes and different boundary conditions at mid-span shroud. Results are verified by experimental data. This method can be applied for blade flutter modeling and suppression of novel engine designs.</p>Flutterstabilityunsteady aerodynamic loadsbladenodal diameterФлаттерустойчивостьнестационарные аэродинамические силылопаткаузловой диаметр
