Abstract : The report presents information which was compiled and generated for development of extremely high altitude tethered balloon systems. These data will be useful in establishing balloon systems and planning estimates. The report includes information on tether cables, balloon materials and balloon configurations. Results of analyses of superpressure natural shape balloons which are reefed as they ascend to and from float altitude are given. Aerodynamic coefficients for a natural shape balloon obtained in wind tunnel tests are also presented. An extensive set of cable and balloon parameter curves is provided for use in establishing multiple balloon systems with natural shape balloons, Class C balloons and Glastran E glass stranded cable. These curves provide cable and balloon data for intermediate altitudes between sea level, 50,000 feet and 100,000 feet. Workable cable-balloon combinations (neglecting ascent and descent conditions) for Summer I and Winter I wind conditions are defined as examples. (Author)
