If a wind vane is devised w hich has practically no overshoot, considerable saving of effort will be achieved in reading and analyzing the indication and chart. A suitable device for this will be to incorporate a damper. In the present paper an oil damper is tested on a model wind vane in the wind tunnel. The degree of necessary damping of the oil damper increases exactly linearly with the wind speed, which fact suggests the necessity of a damper with variable damping. Fundamental design data of the damper and its possible configurations are given.
