Abstract : The history of the development of free balloons to carry heavy payloads into the stratosphere is reviewed with the objective of developing a design based on existing technologies for a balloon to carry 9000 lb to 90,000 ft. Reinforced polyester balloons, in tandem balloon configurations, are discussed with respect to materials, design criteria, and performance. The problem of launch dynamics for single cell polyethylene balloons is also discussed and it is concluded that a capped single cell polyethylene balloon can be dynamically launched, successfully, with the 9000-lb payload. Further, it is concluded that the single cell polyethylene balloon is the best means to meet the objective. Specifications for such a balloon are provided.
