Abstract:

The Stevens Institute Laboratory for Balloon Technology was established in September, 1968 under the sponsorship of the Air Force Cambridge Research Laboratories. This report summarizes the activities of the past three years which include recommendations for the military specification for polyethylene balloon films and the development of new testing methods, gore panel stress analysis of high altitude balloons, the qualification testing of candidate balloon films and failure analysis and design consultation. The major accomplishments are outlined with references to appropriate scientific reports where the details are presented. Where this report constitutes the first formal reporting of results, the details are given.
