The Problem: Instantaneously Effecting Controlled Balloon-System Descent from High Altitude.

Abstract

The need for a technique of instantaneously effect controlled balloon-system descent from high altitude prompted the development efforts reported herein. The background, the approach, test flight data, and the technical problems that frustrated the successful development of the desired technique are included. A simplified model of the shape of a partially full balloon is presented (a model that should also approximate the dimensions of subpressure shapes). Some heretofore unpublished information on apex valve characteristics and subpressure effects are included together with recommendations for any future work of this problem. Significant supplementary findings and historical perspectives are noted. (Author)
