FLIGHT CONTROL SYSTEMS AND LAUNCHING TECHNIQUES FOR AIR BALLAST SYSTEMS

This report examines some of the more practical aspects in the application of air ballast systems to the control of free-flight balloons. Each type of air ballast system, as defined in Scientific Report No. 1, is analyzed for the cost, availability of materials, components, and instrumentation required. In addition, for each type of air ballast system deemed feasible, the possible flight system configurations, associated launching problems, and methods to solve the problems are investigated. It is the conclusion of this report that most air ballast systems can be instrumented and flown with conventional or off-the-shelf components and equipment. Systems using very large payloads are more difficult to handle and launch than smaller payload systems and probably will require some development in new launching techniques and associated equipment.
