Infrared Thermographic NDT-based Damage Detection and Analysis Method for Spacecraft


Book Description

The book focuses on infrared thermographic NDT systems and approaches. Both principles and engineering practice are covered, with more emphasis on the engineering practice of spacecraft damage detection and analysis. This is achieved by providing an in-depth study of several major topics such as infrared feature extraction, damage reconstruction, reconstructed image fusion, reconstructed image stitching, reconstructed image segmentation, defect positioning, defect edge detection and quantitative calculation. A number of application cases are discussed in detail, including impact damage to single-layer and multi-layer protective configurations, simple impact damage, and complex multi-type impact damage. The comprehensive and systematic treatment of practical problems in infrared detection and spacecraft damage identification is one of the main features of this book, which is particularly suitable for those interested in learning practical solutions in infrared detection technology. This book can benefit researchers, engineers, and graduate students in the fields of aerospace design and manufacturing, spacecraft environmental engineering, and non-destructive testing technology, etc.







Design and Fabrication of Large Polymer Constructions in Space


Book Description

Design and Fabrication of Large Polymer Constructions in Space is a ground-breaking study of the polymeric materials, advanced chemical processes, and cutting-edge technology required in the construction of large polymer-based structures for space, when all steps in the process are carried out in the space environment, whether in orbit, in deep space, or on the surface of a moon, asteroid, or planet.The book begins by introducing the fundamentals and requirements of large constructions and inflatable structures for space. The next section of the book focuses on the utilization of polymeric materials within the space environment, examining the effects on materials (vacuum, plasma, temperature), the possible approaches to polymerization both in space and in orbit, the preparation and structure of polymer composites, and the methods for testing materials and structures in terms of strength, defects, and aging. Three chapters then cover how these materials and techniques might be applied to specific categories of construction, including larger space habitats, supporting space structures, and ground infrastructure. Finally, the financial aspects, the consequences for human space exploitation, and the possible future developments are discussed.Using materials science to push the boundaries of construction for space exploration and exploitation, this book is a unique resource for academic researchers and advanced students across polymer science, advanced materials, chemical engineering, construction, and space engineering, as well as for researchers, scientists and engineers at space agencies, companies and laboratories, involved in developing materials or technology for use in space. This is also of great interest to anyone interested in the role of materials science in the building of large space stations, spacecraft, planetary bases, large aperture antenna, radiation and thermal shields, and repairmen sets. Describes the role of polymers in the construction of large space habitats, supporting space structures, and ground infrastructure Explains polymerization in the Earth’s orbit and in space, covering material specifications, control of curing, and the effects of interaction with the external environment Presents the possible testing methods, including strength evaluation, defect detection, and aging tests of materials and constructions




Protection of Materials and Structures from the Low Earth Orbit Space Environment


Book Description

This publication presents the proceedings of ICPMSE-3, the third international conference on Protection of Materials and Structures from the Low Earth Orbit Space Environment, held in Toronto April 25-26, 1996. The conference was hosted and organized by Integrity Testing Laboratory Inc, (ITL), and held at the University of Toronto's Institute for Aerospace Studies (UTIAS), where ITL is located. Twenty industrial companies, seven wliversities and eight government agencies from Canada, USA, United Kingdom, France, Israel, Russia, Ukraine and the Netherlands were represented by over 55 participants indicating increasing international co-operation in this critical arena of protection of materials in space. Twenty-five speakers, world experts in their fields, delivered talks on a wide variety of topics on various aspects of material protection in space, Representatives from the Canadian, American, European and Israeli space agencies as well as from leading space research laboratories of major aerospace industries gathered at UTIAS to discuss the latest developments in the field of material and structure protection from the harsh space environment, These proceedings are organized into four sections: a) AONOV and Radiation Effects on Materials and Structures in the Leo Space Environment; b) Interaction of Matter with the LEO Environment; c) Large Scale Coating Process Developments for Protection in LEO; d) Synthesis and Modification of Materials and Surfaces for Protection in LEO, This is the third in our on-going series of bi-annual international space materials conferences wllich began in 1992 in Toronto.
