• For the purpose of investigating the aerodynamic damping effects on vibrating cascade blades, the authors made a water tunnel with a linear cascade in which five blades vibrate in a translatory mode with arbitrary frequency and phase angle between the adjacent blades. A series of experiments were carried out on an isolated blade and on the cascades with the following conditions : Blades : NACA 65-(12) 10 (fixed : 8,vibrating : 5) chord : 30 mm span : 60 mm solidity : 1 stagger angle : 0°, 30° amplitude of vibration : 2 mm The experimental results were analyzed by comparing with the theoretical ones hitherto obtained and with the aid of the considerations about the quasi-steady force of vibrating blades.
