WIND-TUNNEL EXPERIMENTING APPARATUS

PROBLEM TO BE SOLVED: To restrain an airflow change in the horizontal direction from being attenuated near the wing end part of a vibrating wing in a vibration-type wind- tunnel experimenting apparatus. SOLUTION: In a vibration-type wind-tunnel experimenting apparatus, a plurality of vibrating wings 8 are erected and installed at the entrance of a wind passage in a measuring chamber 6 at a wind tunnel 10 in such a way that they can be turned by motors 9, the vibrating wings 8 are turned, and an airflow change in the horizontal direction is generated in the wind passage. In the experimenting apparatus, when a wing end plate 11 is attached to wing end parts of the vibrating wings 8, it is possible to prevent a straight advancing airflow generated by the vibrating wings 8 from being mixed with a changing airflow from the upper part, and it is possible to restrain the airflow change in the horizontal direction from being attenuated near the wing end parts.
