Download or read book Spacecraft Systems Engineering written by Peter Fortescue and published by Wiley. This book was released on 2003 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following on from the hugely successful previous editions, the third edition of Spacecraft Systems Engineering incorporates the most recent technological advances in spacecraft and satellite engineering. With emphasis on recent developments in space activities, this new edition has been completely revised. Every chapter has been updated and rewritten by an expert engineer in the field, with emphasis on the bus rather than the payload. Encompassing the fundamentals of spacecraft engineering, the book begins with front-end system-level issues, such as environment, mission analysis and system engineering, and progresses to a detailed examination of subsystem elements which represent the core of spacecraft design - mechanical, electrical, propulsion, thermal, control etc. This quantitative treatment is supplemented by an appreciation of the interactions between the elements, which deeply influence the process of spacecraft systems design. In particular the revised text includes * A new chapter on small satellites engineering and applications which has been contributed by two internationally-recognised experts, with insights into small satellite systems engineering. * Additions to the mission analysis chapter, treating issues of aero-manouevring, constellation design and small body missions. In summary, this is an outstanding textbook for aerospace engineering and design students, and offers essential reading for spacecraft engineers, designers and research scientists. The comprehensive approach provides an invaluable resource to spacecraft manufacturers and agencies across the world.
Download or read book Fundamentals of Space Systems written by Vincent L. Pisacane and published by Johns Hopkins University Appli. This book was released on 2005 with total page 872 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Space Systems was developed to satisfy two objectives: the first is to provide a text suitable for use in an advanced undergraduate or beginning graduate course in both space systems engineering and space system design. The second is to be a primer and reference book for space professionals wishing to broaden their capabilities to develop, manage the development, or operate space systems. The authors of the individual chapters are practicing engineers that have had extensive experience in developing sophisticated experimental and operational spacecraft systems in addition to having experience teaching the subject material. The text presents the fundamentals of all the subsystems of a spacecraft missions and includes illustrative examples drawn from actual experience to enhance the learning experience. It includes a chapter on each of the relevant major disciplines and subsystems including space systems engineering, space environment, astrodynamics, propulsion and flight mechanics, attitude determination and control, power systems, thermal control, configuration management and structures, communications, command and telemetry, data processing, embedded flight software, survuvability and reliability, integration and test, mission operations, and the initial conceptual design of a typical small spacecraft mission.

This book was released on 2011-05-26 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book of a series that will focus on MMS (Mechanism and Machine Science). This book also presents IFToMM, the International Federation on the Promotion of MMS and its activity. This volume contains contributions by IFToMM officers who are Chairs of member organizations (MOs), permanent commissions (PCs), and technical committees (TCs), who have reported their experiences and views toward the future of IFToMM and MMS. The book is composed of three parts: the first with general considerations by high-standing IFToMM persons, the second chapter with views by the chairs of PCs and TCs as dealing with specific subject areas, and the third one with reports by the chairs of MOs as presenting experiences and challenges in national and territory communities. This book will be of interest to a wide public who wish to know the status and trends in MMS both at international level through IFToMM and in national/local frames through the leading actors of activities. In addition, the book can be considered also a fruitful source to find out “who’s who” in MMS, historical backgrounds and trends in MMS developments, as well as for challenges and problems in future activity by IFToMM community and in MMS at large.

Download or read book Surface Climates of Canada written by Timothy R. Oke and published by McGill-Queen's Press - MQUP. This book was released on 1998-01-15 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the opening chapters contributors lay out the large-scale context of the physical climate of Canada, introducing the processes, balances, and dynamic linkages between the surface and atmosphere that create and maintain the diversity of surface climates found in Canada as well as outlining the nature of the physical processes that operate near the ground's surface. Individual chapters are dedicated to snow and ice - the almost universal surface cover in Canada - and the other major natural surface environments of Canada: ocean and coastal zones, fresh water lakes, wetlands, arctic islands, low arctic and subarctic lands, forests, and alpine environments. The final part of the book considers those surface environments that have been strongly influenced by human activity, such as agricultural lands and urban environments, and examines the prospects for future climate change. Bringing together for the first time a wide range of scholarship by leading climatologists, The Surface Climates of Canada will be an indispensable tool for understanding Canada's surface climates and the processes responsible for their creation and control.

Download or read book Wind Climate in Cities written by Jack E. Cermak and published by Springer Science & Business Media. This book was released on 1994-11-30 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: If one surveys the development of wind engineering, one comes to the conclusion that the challenge of urban climatology is one of the most important remaining tasks for the wind engineers. But what distinguishes wind engineering in urban areas from conventional wind engineering? Principally, the fact that the effects studied are usually unique to a particular situation, requiring consideration of the surroundings of the buildings. In the past, modelling criteria have been developed that make it possible to solve environmental problems with great confidence, and studies validated the models: at least in a neutrally stratified atmosphere. The approach adopted in the book is that of applied fluid mechanics, since this forms the basis for the evaluation of the urban wind field. Variables for air quality or loads are problem specific, or even random, and methods for studying them are based on risk analysis, which is also presented. Criteria are developed for a systematic approach to urban wind engineering problems, including parameter studies. The five sections of the book are: Fundamentals of urban boundary layer and dispersion; Forces on complex structures in built-up areas; Air pollution in cities; Numerical solution techniques; and Posters. A subject index is included.
