Rare views of the beginnings of a historic space programAfter the excitement of the first Moon landing, the U.S. space program took an ambitious new direction closer to home: NASA's Space Shuttle program promised frequent access to Earth orbit for medical and scientific breakthroughs; deploying, repairing and maintaining satellites; and assembling a space station. Picturing the Space Shuttle is the first photographic history of the program's early years as the world's first space plane debuted. Showcasing over 450 unpublished and lesser-known images, this book traces the growth of the Space Shuttle from 1965 to 1982, from initial concept through its first four space flights. The photographs offer windows into designing the first reusable space vehicle as well as the construction and testing of the prototype shuttle Enterprise. They also show the factory assembly and delivery of the Space Shuttle Columbia, preparations at the major NASA field centers, and astronaut selection and training. Finally, the book devotes a chapter to each of the first four orbital missions, STS-1 through STS-4, providing an abundance of seldom seen photos for each flight. Mostly selected from J. L. Pickering's personal archive, the world's largest private collection of U.S. human space flight images, the high-quality photographs in this book are paired with veteran journalist John Bisney's detailed descriptions and historical background information. The book also includes images of NASA and Shuttle contractor booklets, manuals, access badges, and press kits, as well as a foreword by Robert Crippen, the pilot of the first Space Shuttle flight. Picturing the Space Shuttle recreates the excitement of an era in which the possibilities of space exploration seemed limitless.

This book provides a detailed overview of the theory of analytical and experimental modal analysis and its applications. Modal Analysis is the processes of determining the inherent dynamic characteristics of any system and using them to formulate a mathematical model of the dynamic behavior of the system. In the past two decades it has become a major technological tool in the quest for determining, improving and optimizing dynamic characteristics of engineering structures.
Its main application is in mechanical and aeronautical engineering, but it is also gaining widespread use in civil and structural engineering, biomechanical problems, space structures, acoustic instruments and nuclear engineering.

The only book to focus on the theory of modal analysis before discussing applications
A relatively new technique being utilized more and more in recent years which is now filtering through to undergraduate courses

Following the successful 1st CEAS (Council of European Aerospace Societies) Specialist Conference on Guidance, Navigation and Control (CEAS EuroGNC) held in Munich, Germany in 2011, Delft University of Technology happily accepted the invitation of organizing the 2nd CEAS EuroGNC in Delft, The Netherlands in 2013. The goal of the conference is to promote new advances in aerospace GNC theory and technologies for enhancing safety, survivability, efficiency, performance, autonomy and intelligence of aerospace systems using on-board sensing, computing and systems. A great push for new developments in GNC are the ever higher safety and sustainability requirements in aviation. Impressive progress was made in new research fields such as sensor and actuator fault detection and diagnosis, reconfigurable and fault tolerant flight control, online safe flight envelop prediction and protection, online global aerodynamic model identification, online global optimization and flight upset recovery. All of these challenges depend on new online solutions from on-board computing systems. Scientists and engineers in GNC have been developing model based, sensor based as well as knowledge based approaches aiming for highly robust, adaptive, nonlinear, intelligent and autonomous GNC systems. Although the papers presented at the conference and selected in this book could not possibly cover all of the present challenges in the GNC field, many of them have indeed been addressed and a wealth of new ideas, solutions and results were proposed and presented.

For the 2nd CEAS Specialist Conference on Guidance, Navigation and Control the International Program Committee conducted a formal review process. Each paper was reviewed in compliance with good journal practice by at least two independent and anonymous reviewers. The papers published in this book were selected from the conference proceedingsbased on the results and recommendations from the reviewers.

Beginning with the basic elements that differentiate space programs from other management challenges, Space Program Management explains through theory and example of real programs from around the world, the philosophical and technical tools needed to successfully manage large, technically complex space programs both in the government and commercial environment. Chapters address both systems and configuration management, the management of risk, estimation, measurement and control of both funding and the program schedule, and the structure of the aerospace industry worldwide.

This book discusses all spacecraft attitude control-related topics: spacecraft (including attitude measurements, actuator, and disturbance torques), modeling, spacecraft attitude determination and estimation, and spacecraft attitude controls. Unlike other books addressing these topics, this book focuses on quaternion-based methods because of its many merits. The book lays a brief, but necessary background on rotation sequence representations and frequently used reference frames that form the foundation of spacecraft attitude description. It then discusses the fundamentals of attitude determination using vector measurements, various efficient (including very recently developed) attitude determination algorithms, and the instruments and methods of popular vector measurements. With available attitude measurements, attitude control designs for inertial point and nadir pointing are presented in terms of required torques which are independent of actuators in use. Given the required control torques, some actuators are not able to generate the accurate control torques, therefore, spacecraft attitude control design methods with achievable torques for these actuators (for example, magnetic torque bars and control moment gyros) are provided. Some rigorous controllability results are provided. The book also includes attitude control in some special maneuvers, such as orbital-raising, docking and rendezvous, that are normally not discussed in similar books. Almost all design methods are based on state-spaced modern control approaches, such as linear quadratic optimal control, robust pole assignment control, model predictive control, and gain scheduling control. Applications of these methods to spacecraft attitude control problems are provided. Appendices are provided for readers who are not familiar with these topics.

Aircraft performance is one of the key aspects of the aircraft industry. Starting with the consideration that performance theory is the defining factor in aircraft design, the author then covers the measurement of performance for the certification, management and operation of aircraft. This practical book discusses performance measures which relate to airworthiness certificates (a legal requirement), as well as those needed when compiling the aircraft performance manual for the aircraft. In addition, operational performance is covered, including the financial considerations required by airlines to ensure maximisation of commercial return.

This monograph presents a new analytical approach to the design of proportional-integral-derivative (PID) controllers for linear time-invariant plants. The authors develop a computer-aided procedure, to synthesize PID controllers that satisfy multiple design specifications. A geometric approach, which can be used to determine such designs methodically using 2- and 3-D computer graphics is the result. The text expands on the computation of the complete stabilizing set previously developed by the authors and presented here. This set is then systematically exploited to achieve multiple design specifications simultaneously. These specifications include classical gain and phase margins, time-delay tolerance, settling time and H-infinity norm bounds. The results are developed for continuous- and discrete-time systems. An extension to multivariable systems is also included. Analytical Design of PID Controllers provides a novel method of designing PID controllers, which makes it ideal for both researchers and professionals working in traditional industries as well as those connected with unmanned aerial vehicles, driverless cars and autonomous robots.

Humans and space When faced with the issue of space exploration, one generally has an idea of the ?elds of study and disciplines that are involved: technology, physics and chemistry, robotics, astronomy and planetary science, space biology and medicine, disciplines which are usually referred to as the ?sciences?. In recent discussions, the human element of space exploration has attracted more and more the interest of the space sciences. As a consequence, adjacent disciplines have gained in relevance in space exploration and space research, in times when human space ?ights are almost part of everyday life. These disciplines include psychology and sociology, but also history, philosophy, anthropology, cultural studies, political sciences and law. The cont- bution of knowledge in these ?elds plays an important role in achieving the next generation of space exploration, where humans will resume exploring the Moon and, eventually, Mars, and wherespacetourism isbeginningtobedeveloped. With regard to technology, one might soon be prepared for this. Much less is this the case with space exploration by humans, rather than by robots. Robotic explorations to other planets across the solar system have developed in the past 50 years, since the beginning of the ?space age? with the presence of humans in nearby space and the landing on the Moon. Space exploration is now not only focused on technological achievements, asitsdevelopmentalsohassocial, culturalandeconomicimpacts. This makes human space exploration a topic to address in a cross-disciplinary mann

The field of Large Eddy Simulation (LES) and hybrids is a vibrant research area. This book runs through all the potential unsteady modelling fidelity ranges, from low-order to LES. The latter is probably the highest fidelity for practical aerospace systems modelling. Cutting edge new frontiers are defined.
One example of a pressing environmental concern is noise. For the accurate prediction of this, unsteady modelling is needed. Hence computational aeroacoustics is explored. It is also emerging that there is a critical need for coupled simulations. Hence, this area is also considered and the tensions of utilizing such simulations with the already expensive LES.

This work has relevance to the general field of CFD and LES and to a wide variety of non-aerospace aerodynamic systems (e.g. cars, submarines, ships, electronics, buildings). Topics treated include unsteady flow techniques; LES and hybrids; general numerical methods; computational aeroacoustics; computational aeroelasticity; coupled simulations and turbulence and its modelling (LES, RANS, transition, VLES, URANS). The volume concludes by pointing forward to future horizons and in particular the industrial use of LES. The writing style is accessible and useful to both academics and industrial practitioners.
