ABSTRACT	This paper describes the preliminary test results of a flutter haeing damaged.Tests showed that the device is so effective that flutter was completely suppressed when the angular position of the plate was still less than 10％ of its maximum elevation.Tests were also conducted to evaluate the effects of plate geometry(especially the porosity characteristics)in ferms of its ability to suppress flutter as well as its possible adverse effects on the tunnel driving system,i.e.performance degradation or vibration provocation on the main blower the auxiliary blower or the wind tunnel rotor blade.No degrading effects were observed with this device.
