Summary

This paper describes wind tunnel experimental results of wind-induced responses of a solar wing system, and investigates its aeroelastic instability using a scaled model. The model comprised twelve solar wing units, each supported by two cables. The gaps between units were set constant. Two sag ratios (i.e. sag/span length) were adopted. The wind speed was varied from 0 to 16m/s, and eighteen different wind speeds were used. From the experiment, when the sag was 2 percent, a sudden increase in fluctuating displacement was found near a mean wind speed of 10m/s at a wind direction of 40 degrees. A sudden increase in fluctuating displacements was also found near a mean wind speed of 1m/s when the wind direction was larger than 60 degrees. When the sag increased to 5 percent, some differences among units in mean displacements were found and complicated vibration in fluctuating displacement at low wind speed was observed.
