Aerospace and Mechanical Engineering2019<p>Results of a dynamic condition experimental research of the modern three-stage blisk fan designs, designed on new calculated technologies are resulted. Features of rotor blades fluctuations are revealed at research of a flutter in stalling area. As a result of the carried out experimental research the conclusion that there are two kinds of a subsonic cascade flutter is made: without-stalling flutter to which there corresponds the wave of deformation running on rotation and a stalling flutter at which the wave of deformation runs against rotation.</p>Флаттервращающийся срывсрывное обтеканиевентиляторрабочие лопаткиволны деформациипульсации потокаFlutterrotating stallstalling airflowfanrotor bladeswaves of deformationflow pulsation
