A series of experiments, by means of a small wind tunnel, were made to find out the best type of astrodome structures where the wind load acted on the radio dish was reduced to the minimum. It was especially desired to reduce the positional and pitching moments, directly related to servomechanism system and tracking accuracy.After making a series of experimental researches, a final plan was chosen with D = 28m. H=10m. and three fences of hindering rotary flow. This astrodome, while given a last test in a large wind tunnel for checking-up results, was finally approved.
