The Balloon And Its Application

Stratospheric balloons are powerful tools used to study the Earth and its atmosphere, as well as the greater cosmos beyond. This book describes the science and technology behind modern stratospheric ballooning, along with the surprising ways it has impacted our daily lives. The book takes you through every step of the process, starting with an in-depth introduction to basic balloon types and their uses before delving into balloon construction and mission planning. Along the way, you will learn about the novel technologies that have radically changed these balloons and their ability to launch, control and navigate them over specific ground targets. Next follows an exploration of their incredible applications, including research in atmospheric science, cosmology and astronomy, earth studies, meteorology, and aerobiology, and also commercial capabilities such as Internet networks and high-altitude tourism. The community of scientists, engineers, and entrepreneurs involved in stratospheric ballooning is only ever growing. This book shows you how these national and international efforts have truly soared in recent years, and it will be an enjoyable read for anybody interested in learning more about how science and commerce are conducted in the stratosphere, at the edge of space.

Experiments with rubber balloons and rubber sheets have led to surprising observations, some of them hitherto unknown or not previously described in the literature. In balloons, these phenomena are due to the non-monotonic pressure-radius characteristic which makes balloons a subject of interest to physicists engaged in stability studies. Here is a situation in which symmetry breaking and hysteresis may be studied analytically, because the stress-stretch relations of rubber - and its non-convex free energy - can be determined explicitly from the kinetic theory of rubber and from non-linear elasticity. Since rubber elasticity and the elasticity of gases are both entropy-induced, a rubber balloon represents a compromise between the entropic tendency of a gas to expand and the entropic tendency of rubber to contract. Thus rubber and rubber balloons furnish instructive paradigms of thermodynamics. This monograph treats the subject at a level appropriate for post-graduate studies.

The aim of this book is to introduce scientific ballooning to the many people who are interested in the use of balloons for scientific applications. The book offers a basic understanding of the engineering details and the scientific research giving rise to balloon activities going on today. Above all, the book will serve as a guidebook for young scientists and researchers seeking to become involved in space science and technology by participating in balloon projects. The book deals with three types of balloons: large stratospheric balloons used for scientific purposes, rubber balloons used for aerological observations, and planetary balloons to be used in the atmospheres of other planets. The book provides many figures and photographs, and offers a systematic description of balloon technologies and related matters from historical background to current research topics. The contents include a theoretical discussion of ballon shape design, analysis and synthesis of flight dynamics, actual launching procedure, flight operations, and typical applications of ballooning in various scientific fields. Detailed meteorological descriptions, especially of the Earth's stratosphere and the atmosphere of other planets, are provided for investigating actual flight behavior.

“Inside information on a wondrously droll, highly classified yarn from WWII . . . A well-told, stranger-than-fiction tale that could make a terrific movie.” —Kirkus Reviews The plan: attach small incendiary bombs to millions of bats and release them over Japan’s major cities. As the bats went to roost, a million fires would flare up in remote crannies of the wood and paper buildings common throughout Japan. When their cities were reduced to ashes, the Japanese would surely capitulate . . . Told here by the youngest member of the team, this is the story of the bat bomb project, or Project X-Ray, as it was officially known. In scenes worthy of a Capra or Hawks comedy, Jack Couffer recounts the unorthodox experiments carried out in the secrecy of Bandera, Texas, Carlsbad, New Mexico, and El Centro, California, in 1942-1943 by “Doc” Adams’ private army. This oddball cast of characters included an eccentric inventor, a distinguished Harvard scientist, a biologist with a chip on his shoulder, a movie star, a Texas guano collector, a crusty Marine Corps colonel, a Maine lobster fisherman, an ex-mobster, and a tiger. The bat bomb researchers risked life and limb to explore uncharted bat caves and “recruit” thousands of bats to serve their country, certain that they could end the war with Japan. And they might have—in their first airborne test, the bat bombers burned an entire brand-new military airfield to the ground. For everyone who relishes true tales of action and adventure, Bat Bomb is a must-read. Bat enthusiasts will also discover the beginnings of the scientific study of bats.
