Abstract
Although the solid and the 25 percent porous thin paraboloidal dishes were instrumented with static pressure tubes and tested in the wind tunnel, the porosity used for the 64-m antenna was 50 percent for economic reasons. The extrapolation to 50 percent porosity, to date, has resulted in conservative values. This report describes a method of extrapolating from the available data the 50 percent porous pressure coefficient differences. The method is verified by checking the available wind tunnel static pressure data against the force data.
