This volume by an astrophysics pioneer concerns the phenomena occurring during the flight of meteors through the terrestrial atmosphere. Beginning with a historical view of the study of meteor activity, the text examines atmospheric conditions and the classification and physico-chemical properties of meteors. Also includes meteoroid energy transfer, ablation, atomic collisions, and meteor radiation.

Meteor Showers and their Parent Comets is a unique handbook for astronomers interested in observing meteor storms and outbursts. Spectacular displays of 'shooting stars' are created when the Earth's orbit crosses a meteoroid stream, as each meteoroid causes a bright light when it enters our atmosphere at high speed. Jenniskens, an active meteor storm chaser, explains how meteoroid streams originate from the decay of meteoroids, comets and asteroids, and how they cause meteor showers on Earth. He includes the findings of recent space missions to comets and asteroids, the risk of meteor impacts on Earth, and how meteor showers may have seeded the Earth with ingredients that made life possible. All known meteor showers are identified, accompanied by fascinating details on the most important showers and their parent comets. The book predicts when exceptional meteor showers will occur over the next fifty years, making it a valuable resource for both amateur and professional astronomers.

A survey is made of recent papers on the physics of meteor entry. The various regimes of luminous flight are defined, and present techniques for obtaining the mass and density of meteoroids are critically discussed. The effect of the assumed mode of heat transfer on the mass loss is shown for two recent fireballs. A relatively simple method for estimating original mass and velocity is presented. It is evident from this paper that many questions remain to be answered, particularly those concerning radiation from the gas and ablated material, before the entry of objects larger than those which produce telescopic meteors can be successfully analyzed.

This book offers a unified presentation that does not discriminate between atmospheric and space flight. It demonstrates that the two disciplines have evolved from the same set of physical principles and introduces a broad range of critical concepts in an accessible, yet mathematically rigorous presentation. The book presents many MATLAB and Simulink-based numerical examples and real-world simulations. Replete with illustrations, end-of-chapter exercises, and selected solutions, the work is primarily useful as a textbook for advanced undergraduate and beginning graduate-level students.

Environmental Testing Techniques for Electronics and Materials reviews environmental testing techniques for evaluating the performance of electronic equipment, components, and materials. Environmental test planning, test methods, and instrumentation are described, along with the general environmental conditions under which equipment must operate. This book is comprised of 15 chapters and begins by explaining why environmental testing is necessary and describing the environment in which electronics must operate. The next chapter considers how an environmental test plan is designed; the methods for the environmental testing of components and materials; instrumentation and control of test chambers; shock and vibration test instrumentation; and requirements for specification writing. The reader is then introduced to factors that might affect the reliability of equipment, including high humidity environment; galvanic corrosion problems; high- and low-temperature environments; mechanical and associated hazards; transport hazards; and long-term storage. Problems posed by high altitude and space environments, nuclear radiation, and acoustic noise are also discussed. The final chapter is devoted to environmental protection techniques and looks at the effects of climatic environments on radio interference as well as the effects of the environment on the human operator. This monograph will be of value to materials scientists and electronics engineers as well as those engaged in the design, development, and production of professional and military equipment.

The High Temperature Aspects of Hypersonic Flow is a record of the proceedings of the AGARD-NATO Specialists' Meeting, held at the Technical Centre for Experimental Aerodynamics, Rhode-Saint-Genese, Belgium in April 1962. The book contains the papers presented during the meeting that tackled a broad range of topics in the aspects of hypersonic flow. The subjects covered during the meeting include pressure measurements, interference effects, the use of wind tunnels in aircraft development testing, high temperature gas characteristics, boundary layer research, stability and control and the use of rocket vehicles in flight research. Aerospace engineers and aeronautical engineers will find the book invaluable.
