Final report of USAF Geophysics Laboratory program undertaken in 1973 to develop superior tethered balloon material and design and fabricate a 45,000 cu. ft. tethered balloon from the developed material. A new empennage ripstop fabric of combined Kevlar and pre-heat set Dacron yarns, and a new hull fabric which is a biaxially woven fabric stabilized with an oriented non-woven polyester fabric, were developed. A 45,000 cu. ft. balloon was designed, fabricated and tested. The new material is suitable for construction of balloons in the 100,000 cu. ft. range. The hull fabric developed on this program was later scaled-up and is currently used in USAF 250,000 cu. ft. Seek Skyhook Aerostats. (Author)
