Описание: Presents information on the various aspects of spacecraft power system design, analysis, and operation for various types of spacecrafts: earth-orbiting, interplanetary, and deep-space. This work presents modern data and procedures for designing electrical power systems that meet mission requirements at a minimum cost and weight.
Описание: As a stand-alone volume, Transistor Circuits For Spacecraft Power System presents numerous transistor circuits and building blocks associated with power electronics in general, and examines the major subsystem components for solar-based spacecraft power systems. The technique and concept, of "continuity of states" for nonlinear circuits handling power transfer under cyclic excitation is introduced in Part I and further developed throughout the book. This powerful technique employing matrix formulation bypasses eigen-transients and yields steady-state responses rapidly. Closed-loop treatments are also given for large-scale linear circuits, many closed-form solutions for control loop-gain, conducted susceptibility, output impedance, etc. are covered. Extensive mathematical procedures are retained to highlight the importance of analytical flows.The author also reviews the evolution of solar-based spacecraft power systems; introduces modes of operations: discharge (boost), shunt, and charge; and covers pulse-width-modulated (PWM) boost power converter for both DC and AC conditions. A configuration tree for shunt mode operation is conceived. Based on the configuration tree, the best topologies, sequential PWM shunt and ripple-regulated free-running shunt, are intensively examined and formulated.Transistor Circuits For Spacecraft Power System provides important information for understanding the relationship between earthbound semiconductor circuits and space borne vehicles.

Описание: Explains aerodynamic and astrodynamic flight without the use of mathematics for non-technical readers who are interested in spaceflight and spacecraft. This book provides the historical context upon which the developments in spaceflight have been built.
Описание: Encompassing the fundamentals of spacecraft engineering, this 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, and control.
Описание: The material in this book is essential for engineers studying and working in the field of spececraft design. The unique feature of this book is that its coverage aims at giving the breadth which is needed by system engineers, with an emphasis on the bus aspect rather than on the payload. This second edition is an updated of the first, and includes two estra chapters. The first is on Mechanisms, and the second is on the subhject of Systems Engineering, and it includes examples of applications to different types of missions.
Описание: In Future Spacecraft Propulsion Systems the authors demonstrate the need to break free from the old established concepts of expendable rockets, using chemical propulsion, and to develop new breeds of launch vehicle capable of both launching payloads into orbit at dramatically reduced cost, and for sustained operations in low-Earth orbit. The next steps, they explain, to establishing a permanent "presence" in the solar system beyond Earth are the commercialisation of sustained operations on the Moon, and the development of advanced nuclear or high-energy space propulsion systems for solar system exploration out to the boundary of interstellar space. In the future, high-energy particle research facilities may one day yield a very high-energy propulsion system that will take us to the nearby stars, or even beyond. This is a timely and comprehensive book, putting spacecraft propulsion systems in perspective.

Описание: Simulation tools strongly changed the development of satellites and spacecraft over the years. This book gives a depiction how system simulators are applied for the development and verification of space vehicles. It shows the usage of simulations for various processes: engineering and design process, and numerical studies and software engineering.
Описание: Mission Geometry; Orbit and Constellation Design and Management (OCDM) is the most complete treatment available for many elements of space mission design and astronautics. Among these topics not covered elsewhere in the literature are:
The most extensive coverage available of constellation design and management;
Relative motion of satellites (global, local, at similar and widely differing altitudes);
Definition of an Orbit CostFunction for comparing the cost of access to and maintenance of alternative orbits;
Most extensive discussions available of autonomous navigation and autonomous orbit control;
The most complete discussion available of Earth coverage and viewing andlighting conditions;
Apparent motion of other satellites needed for cross-link pointing and antenna coverage;
Analytic expressions for the field of view of an array processor on the celestial sphere and projected onto the Earth's surface;
Detailed process for creating and analyzing mapping, pointing, and timing budgets;
Closed-form expressions for the ground track of a circular orbit, including high accuracy approximations for ground station coverage;
Convenient formulas for specialized orbits about the Earth and other planets;
Practical spacecraft problems such as time discontinuities, GPS coverage at satellite altitudes, and how to identify and handle singularities in measurement sets; and
New solutions for all possible spherical triangles without quadrant ambiguities and allowing all sides and angles to range from 0 to 360 deg.
OCDM discusses both the similarities and differences between orbit and altitude systems in terms of hardware, algorithms, design, and processing requirements. With the demand for reduced cost and the introduction of extensive on-board computing, what were once entirely separate disciplines have begun to merge. This volume will speed that process.
In all areas, OCDM is meant to be practical, with recommendations, insights, formulas, and numerical recipes based on 40 years of spaceflight experience from organizations worldwide. It is meant to be both a text and reference work that can be used by those entering the field and by senior engineers engaged in the design, analysis, construction, or on-orbit operations of orbit and attitude systems and components.
Описание: A comprehensive presentation of data, theory and practice in attitude analysis. It features discussions of common data anomalies, data validation, attitude hardware and associated mathematical models, and a presentation of geometrical procedures for mission analysis and attitude accuracy studies which can eliminate many complex simulations.

Описание: Describes the integral process of developing cost-effective, reliable structures and mechanical products for space programs. This book defines processes, describes methods, and gives examples. It is suitable for system engineers, mechanical designers, stress analysts, dynamics and load analysts, technical leads, and program managers.
Описание: The revised edition of this practical, hands-on book discusses the range of launch vehicles in use today throughout the world, and includes the very latest details of some of the advanced propulsion systems currently being developed. The author covers the fundamentals of the subject, from the basic principles of rocket propulsion and vehicle dynamics through the theory and practice of liquid and solid propellant motors, to new and future developments.The revised edition will stick to the same principle of providing a serious exposition of the principles and practice of rocket propulsion, but from the point of view of the user and enquirer who is not an engineering specialist. Most chapters will remain substantially the same as the first edition; they will be updated where necessary and errata corrected. The main revisions will be to the chapter on electric propulsion where there have been significant new developments both in engine types and in practical applications. This is now seen as the key to planetary exploration by robotic probes and should therefore be reflected. Nuclear propulsion has emerged from the doldrums and is now seen as a definite possibility for outer solar system robotic exploration; and as enabling technology for a human mars expedition. A new chapter on nuclear thermal propulsion has been added to reflect this revival of interest.
