Abstract: PURPOSE:To prevent a cantilever wing model with a fixed part of 100% or less from being damaged by controlling fixing conditions of a supporter with vibration damper for supporting a free end of a wing base by a detection signal from a response signal detector of the wing. CONSTITUTION:A 50%-fixed delta wing model 5 which is a test piece is attached to a wing model fixing attachment block 4. A controller 11 controls a solenoid valve 9 by a response signal 13 from a distortion gage 8 which detects an output/input control signal 12 of the wing 5 or a response of the wing 5. A support arm 7 of a supporter 6 with vibration damper fixed to the block 4 moves in parallel or opens/closes by 180 degrees by activation of an actuator to support or make a free end of a wing base of the wing 5 free. The controller 11 frees the arm 7 only during experimental data measurement, while otherwise the wing 5 supports the wing 5 from both sides to prevent its damage. If a flutter occurs during data measurement, the arm 7 is actuated by the signal 13 so as to absorb fluctuation energy of the wing 5 by the damper to prevent the wing 5 from being damaged.
