Measuring of the profile vibration on the flutter critic flow velocity
Original language description
Experimental facility situated in the test section of the wind tunnel suction type was adjusted both in the total construction and in the construction of the fluttering body, the methodology of the measurement and evaluation of the flow and dynamic parameters during flutter were also changed. Preserved was the conception of the NACA0015 profile with two degrees of freedom, rotational and translational. Torque elasticity was now realized by the coil spring and changed by different length of this spring or by different diameter of the spring wire. The pitch angle of the profile was now measured by the magnetic rotary encoder. The translational position was indicated by the magnetic linear encoder and was centered by plane springs situated on both ends ofthe shiftable frame. With this model the testing measurement was realized by its self-excited vibration of flutter type in the range of Mach numbers M=0.20-0.215 and Reynolds numbers 263 000 ? 283 000. Results obtained with M=0.21 and Re
