Abstract
The characteristics of the aerodynamic interblade interaction of the vibrating cascade in transonic flow are examined by a one-blade oscillation method and some aspects of aerodynamic interblade interaction which are hidden in case of the conventional all-blades vibration method are clarified. In the report, the effects of the compressibility of the flow on the aerodynamic interactions are clarified and the reasons why the characteristics of the aerodynamic damping of the uniform cascade are varied with the Mach number, reduced frequency and interblade phase angle are elucidated.
