DEVELOPMENT OF 100,000-FOOT, DUAL-PURPOSE, FAST-RISE BALLOON.
Abstract
Work was conducted in the following areas: Neoprene and natural rubber compounds having suitable physical properties were developed. A simple wind tunnel was made for the evaluation of prototype balloons. A number of composite spherical and streamlined balloons were constructed, ranging from two-piece balloons to four-piece assemblies. Flight testing of these models was conducted in order to determine the best design. Ten engineering models were submitted, and the construction was modified and improved in later submissions. Among these modifications were changes to ensure the survival of the inner balloon in composite balloon assemblies and changes to ensure the falling away of the outer balloon after burst. The effect of mechanical attachments, such as fins and streamers, was evaluated. (Author)
