STUDY OF PHYSICAL AND CHEMICAL CHARACTERISTICS OF BALLOONS AND BALLOON MATERIALS.
Abstract
The possibility of reaching an altitude of 100,000 ft. with a 750-g balloon made from compound A5-105 and flown with a lower free lift was investigated with only moderate success. A group of flights was performed with a view to increasing the rate of ascent of 100,000-ft balloons. Fifteen balloons designed for flight in the tropical zone were flown in the Canal Zone with excellent results, 83% reaching altitudes in excess of 100,000 ft. Two compounds were designed for high ozone resistance and low IR absorption. Laboratory tests indicated that these objectives were achieved, and 1000-g balloons made from one of these compounds performed satisfactorily and extremely consistently. Twelve balloons ranging in wt. from 1500 to 2500 g manufactured from compound A5-101 displayed excellent altitude performance and good consistency. The 2500-g balloons average almost 140,000 ft.
