Description	Large length and small blade thickness of the last stages of steam turbines requires checking of blade rows flutter stability.In the presented work the computation of non-stacionary aerodynamic loads in peripheral section of one of such rings is carried out.The calculation is executed within the framework of an ideal compressible fluid model.The analysis of work of aerodynamic loading at bending and torsional moving of blades allows to assume possible zones of flutter existence.The main independent va riables in the given cascade are :inlet Mach number,incidence angle,interblade phase and reduced frequency of vibrating profiles in bending and torsion.The result is given by work performed during one vibration cycle.That one shows, whether the oscillat ions are stable or unstable.
