Book Description
Mesoscale observations of summertime minimum wind fields in the lower stratosphere disclose a complex mesostructure in the winds located between the stratospheric easterlies and tropospheric westerlies. Anticyclonic rotation of wind directions appears to predominate but speeds, although low, are highly variable. There are a number of layers, averaging 1000 ft thick, that have a speed of less than 10 kt. These layers seem to have no traceable continuity in time or space. There is evidence of significant inertial influence on winds of less than 10 kt. Two sets of data were obtained from radiosondes with extended power supplies carried on large plastic balloons that made slow ascents and descents through this region of the atmosphere. The success of these ventures supports the concept of using free-floating and tethered balloons as hovering or station-keeping vehicles. (Author).

Book Description
The document covers a series of papers given at the fifth AFCRL scientific balloon symposium. The subjects were selected to cover the most recent developments in balloon technology and examples of the use of balloons for research purposes. The symposium is intended to provide an exchange of information for the developers of balloon systems and provides an excellent opportunity for scientists to discuss potential balloon capabilities and applications for the accomplishment of scientific programs. Balloon technology presentations included recent material investigations, tandem balloon stress analysis, balloon instrumentation, tethered balloons, cryoinflation feasibility studies and proposed launching techniques for large balloon systems.

Book Description
The annotated bibliography has evolved from an informal compilation prepared in response to many requests from military and civilian researchers who were planning balloon-borne experiments and searching for data or detailed information concerning some specific aspects of modern scientific ballooning operations. The bibliography consists of three parts: a subject index, an author index, and the bibliography with annotations.

Book Description
The report contains the papers presented at the Seventh AFCRL Scientific Balloon Symposium held in September 1972. The papers were presented in three sessions: Tethered and powered balloons, balloon-borne experiments, and instrumentation and balloon technology. In the area of tethered balloons, papers were presented on cables, drag and stability characteristics, hull design and analysis, and the results of scientific experiments using tethered balloons as sensor platforms. Papers were presented on a powered spherical balloon and a survey of possible power sources for use by this system. Presentations during the balloon-borne experiments and instrumentation session included manned balloon flights, precision pointing and control platforms and instrumentation, recovery parachute performance, gondola motion analyses, a balloon radar altimeter, and an overview of French scientific ballooning activities. During the balloon technology session a review was made of the flight results and performance of balloons with volumes in excess of 20 million cubic feet, shape and stress analysis of both nonreinforced and reinforced materials, and fabric tinting to increase solar absorptivity.

Book Description
The report describes POBAL, a test flight to demonstrate the feasibility of accomplishing station-keeping by powering a 711,000-cu. ft. free balloon against the wind in the minimum wind field near 60,000-ft altitude. The propulsion system, fabricated from off the shelf components, incorporated a 35-ft diameter helicopter rotor and an 8-hp electric motor powered by Ag-Zn batteries. Line of thrust was controlled by a 9-ft high rudder, steerable either by radio command or by autopilot. POBAL was flown from Holloman AFB, New Mexico in September 1972. System components, flight results, recommendations and feasibility studies for a long duration POBAL system are discussed. (Author).
