Deep Space Flight And Communications

RRP $137.95

The majority of books dealing with prospects for interstellar flight tackle the problem of the propulsion systems that will be needed to send a craft on an interstellar trajectory. The proposed book looks at two other, equally important aspects of such space missions, and each forms half of this two part book.

Part 1 looks at the ways in which it is possible to exploit the focusing effect of the Sun as a gravitational lens for scientific missions to distances of 550 AU and beyond into interstellar space. The author explains the mechanism of the Sun as a gravitational lens, the scientific investigations which may be carried out along the way to a distance of 550 AU (and at the 550 AU sphere itself), the requirements for exiting the Solar System at the highest speed and a range of project ideas for missions entering interstellar space.

Part 2 of the book deals with the problems of communicating between an interstellar spaceship and the Earth, especially at very high speeds. Here the author assesses a range of mathematical tools relating to the Karhunen-LoÅ ve Transform (KLT) for optimal telecommunications, technical topics that may one day enable humans flying around the Galaxy to keep in contact with the Earth. This part of the book opens with a summary of the author's 2003 Pesek Lecture presented at the IAC in Bremen, which introduces the concept of KLT for engineers and 'newcomers' to the subject. It is planned to include a DVD containing the full mathematical derivations of the KLT for those interested in this important mathematical tool whilst the text itself will contain the various results without outlines of the mathematical proofs. Astronautical engineers will thus be able to see the application of the results without getting bogged down in the mathematics.

Recent achievements in sunlight concentration techniques have increased the potential of solar power as a viable source of renewable energy. Through its critical analysis of current methods, Photovoltaic Conversion of Concentrated Sunlight provides a comprehensive treatment of the issues involved in the creation of an efficient and cost-effective sustainable power resource. The authors introduce significant new original research and offer an insight into previously inaccessible Russian studies. Logically structured, the text presents both theoretical and practical advances in the field. Features include:<br> * Discussion of fabrication problems for both terrestrial and space photovoltaic installations<br> * Investigation of the impact of resistive losses on the operation of solar cells and new procedures for measuring components of internal resistance<br> * Explanation of the semiconductor physics underlying photovoltaics<br> * Examination of the most efficient concentrator solar cell structures and materials plus exploration of ways to improve cell performance<br> * Original theoretical and experimental results on luminescence phenomena in concentrator cells<br> * Useful measurement techniques for the determination of diagnostic cell parameters<br> * Analysis of energy characteristics of photovoltaic installations with high and low concentration ratios<br> An invaluable asset to industrialists and academics concerned with semiconductors and photovoltaics, this book will also serve environmental scientists through its examination of the problems associated with large-scale use of this ecological technology.


Theory Of Interplanetary Flights

RRP $257.99

This unique monograph contains a comprehensive overview of celestial mechanics, providing the reader with a solid basis on which to build an understanding of the theory of interplanetary flights. The theoretical development is illustrated with a number of practical examples, bringing to bear the author's wealth of experience gained from working of the Soviet space programme. Many examples are taken from current space topics, including the Shoemaker-Levy 9 comet, the flight of Ulysses over the Solar poles, and the Voyagers' tour of the Solar system. Recent theoretical achivements, such as the intriguing problem of chaos in the Solar system, are also covered.
This book will appeal to students and researchers interested in both the theoretical and applied aspects of the topic. The clarity of the exposition renders the subject matter accessible to senior undergraduates and graduate students of mathematics, physics and astrophysics.


A Solar Car Primer 2015

RRP $381.99

Click on the Google Preview image above to read some pages of this book!

This exciting primer on Solar Racing literally starts from the ground up, describing how the interactions of a vehicle with its environment circumscribe its ultimate success, from aerodynamics to resistance and propulsion. By demonstrating how to mathematically model these underlying physical phenomena, the author helps solar racing competitors carefully select key characteristics of the vehicle, such as weight and shape, to produce optimal speed. Energy conversion and demand are given particular attention, followed by chapters devoted to examining solar racers' design, manufacture and testing using a structured problem-solving process to keep projects on track and on schedule. A chapter devoted to energy management strategies provides invaluable tips on maximizing average speed during a race. Complex issues such as ventilation system analysis and performance simulation are covered in dedicated appendices. The financial aspect of project design is not neglected, as both fund-raising and cost estimation are given in-depth consideration.
