Download or read book Simulating Spacecraft Systems written by Jens Eickhoff and published by Springer Science & Business Media. This book was released on 2009-09-25 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Satellite development worldwide has significantly changed within the last decade and has been accelerated and optimized by modern simulation tools. The classic method of developing and testing several models of a satellite and its subsystems with the aim to build a pre-flight and finally a flight model is being replaced more and more by a considerably faster and more inexpensive method. The new approach no longer includes functional test models on entire spacecraft level but a system simulation. Thus overall project runtimes can be shortened. But also significantly more complex systems can be managed and success oriented tests on integration and software level can be realized before the launch. Applying modern simulation infrastructures already during spacecraft development phase, enables the consistent functionality checking of all systems both in detail and concerning their interaction. Furthermore, they enable checks of the system's proper functionality, their reliability and safety / redundancy. But also analysis regarding aging and lifetime issues can be performed by simulation. Project-related simulations of operational scenarios, for example with remote sensing satellites, and the checking of different operational modes are of similar importance. On the whole, risk is reduced significantly and the satellite can be produced in a considerably more cost efficient way, with higher quality and in shorter periods of time. Therefore "Simulating Spacecraft Systems" - the title of the present book - is an important domain of modern system engineering, which meanwhile has successfully established a position in many other sectors of industry and research, too.

Book Synopsis Computer Simulations of Space Societies by : William Sims Bainbridge
Download or read book Computer Simulations of Space Societies written by William Sims Bainbridge and published by Springer. This book was released on 2019-01-05 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the intersection of astronautics, computer science, and social science, this book introduces the challenges and insights associated with computer simulation of human society in outer space, and of the dynamics of terrestrial enthusiasm for space exploration. Never before have so many dynamic representations of space-related social systems existed, some deeply analyzing the logical implications of social-scientific theories, and others open for experience by the general public as computer-generated virtual worlds. Fascinating software ranges from multi-agent artificial intelligence models of civilization, to space-oriented massively multiplayer online games, to educational programs suitable for schools or even for the world's space exploration agencies. At the present time, when actual forays by humans into space are scarce, computer simulations of space societies are an excellent way to prepare for a renaissance of exploration beyond the bounds of Earth.

Available in PDF, EPUB and Kindle. Book excerpt: A real-time computer-hardware simulation for the investigation of space station dynamics and control problems is described. The simulation utilizes full-scale control moment gyro (CMG) hardware mounted on a moving base simulator, a manual console, and a Control Data (CDC) 6600 digital computer to represent a space station and its control system. The digital computer software is programed in modular form by using separate subroutines or modules to represent the simulated spacecraft, onboard control computer, isolated experiment packages, and other disturbance or dynamics functions associated with space station operation. A complete functional and operational description of the major elements of the space station simulation is included.
Book Synopsis Dynamics and Simulation of Flexible Rockets by : Timothy M. Barrows
Download or read book Dynamics and Simulation of Flexible Rockets written by Timothy M. Barrows and published by Academic Press. This book was released on 2020-12-10 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics and Simulation of Flexible Rockets provides a full state, multiaxis treatment of launch vehicle flight mechanics and provides the state equations in a format that can be readily coded into a simulation environment. Various forms of the mass matrix for the vehicle dynamics are presented. The book also discusses important forms of coupling, such as between the nozzle motions and the flexible body. This book is designed to help practicing aerospace engineers create simulations that can accurately verify that a space launch vehicle will successfully perform its mission. Much of the open literature on rocket dynamics is based on analysis techniques developed during the Apollo program of the 1960s. Since that time, large-scale computational analysis techniques and improved methods for generating Finite Element Models (FEMs) have been developed. The art of the problem is to combine the FEM with dynamic models of separate elements such as sloshing fuel and moveable engine nozzles. The pitfalls that may occur when making this marriage are examined in detail. Covers everything the dynamics and control engineer needs to analyze or improve the design of flexible launch vehicles Provides derivations using Lagrange’s equation and Newton/Euler approaches, allowing the reader to assess the importance of nonlinear terms Details the development of linear models and introduces frequency-domain stability analysis techniques Presents practical methods for transitioning between finite element models, incorporating actuator dynamics, and developing a preliminary flight control design

Book Synopsis NASA Space Technology Roadmaps and Priorities by : National Research Council
Download or read book NASA Space Technology Roadmaps and Priorities written by National Research Council and published by National Academies Press. This book was released on 2012-06-07 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's Office of the Chief Technologist (OCT) has begun to rebuild the advanced space technology program in the agency with plans laid out in 14 draft technology roadmaps. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development and its technology base has been largely depleted. However, success in executing future NASA space missions will depend on advanced technology developments that should already be underway. Reaching out to involve the external technical community, the National Research Council (NRC) considered the 14 draft technology roadmaps prepared by OCT and ranked the top technical challenges and highest priority technologies that NASA should emphasize in the next 5 years. This report provides specific guidance and recommendations on how the effectiveness of the technology development program managed by OCT can be enhanced in the face of scarce resources.

Book Synopsis Simulation of Thermoelastic Behaviour of Spacecraft Structures by : Simon Appel
Download or read book Simulation of Thermoelastic Behaviour of Spacecraft Structures written by Simon Appel and published by Springer Nature. This book was released on 2021-08-31 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides recommendations for thermal and structural modelling of spacecraft structures for predicting thermoelastic responses. It touches upon the related aspects of the finite element and thermal lumped parameter method. A mix of theoretical and practical examples supports the modelling guidelines. Starting from the system needs of instruments of spacecraft, the reader is supported with the development of the practical requirements for the joint development of the thermal and structural models. It provides points of attention and suggestions to check the quality of the models. The temperature mapping problem, typical for spacecraft thermoelastic analysis, is addressed. The principles of various temperature mapping methods are presented. The prescribed average temperature method, co-developed by the authors, is discussed in detail together with its spin-off to provide high quality conductors for thermal models. The book concludes with the discussion of the application of uncertainty assessment methods. The thermoelastic analysis chain is computationally expensive. Therefore, the 2k+1 point estimate method of Rosenblueth is presented as an alternative for the Monte Carlo Simuation method, bringing stochastic uncertainty analysis in reach for large thermoelastic problems.
Book Synopsis Spacecraft Dynamics and Control by : Enrico Canuto
Download or read book Spacecraft Dynamics and Control written by Enrico Canuto and published by Butterworth-Heinemann. This book was released on 2018-03-08 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft Dynamics and Control: The Embedded Model Control Approach provides a uniform and systematic way of approaching space engineering control problems from the standpoint of model-based control, using state-space equations as the key paradigm for simulation, design and implementation. The book introduces the Embedded Model Control methodology for the design and implementation of attitude and orbit control systems. The logic architecture is organized around the embedded model of the spacecraft and its surrounding environment. The model is compelled to include disturbance dynamics as a repository of the uncertainty that the control law must reject to meet attitude and orbit requirements within the uncertainty class. The source of the real-time uncertainty estimation/prediction is the model error signal, as it encodes the residual discrepancies between spacecraft measurements and model output. The embedded model and the uncertainty estimation feedback (noise estimator in the book) constitute the state predictor feeding the control law. Asymptotic pole placement (exploiting the asymptotes of closed-loop transfer functions) is the way to design and tune feedback loops around the embedded model (state predictor, control law, reference generator). The design versus the uncertainty class is driven by analytic stability and performance inequalities. The method is applied to several attitude and orbit control problems. The book begins with an extensive introduction to attitude geometry and algebra and ends with the core themes: state-space dynamics and Embedded Model Control. Fundamentals of orbit, attitude and environment dynamics are treated giving emphasis to state-space formulation, disturbance dynamics, state feedback and prediction, closed-loop stability. Sensors and actuators are treated giving emphasis to their dynamics and modelling of measurement errors. Numerical tables are included and their data employed for numerical simulations. Orbit and attitude control problems of the European GOCE mission are the inspiration of numerical exercises and simulations. The suite of the attitude control modes of a GOCE-like mission is designed and simulated around the so-called mission state predictor. Solved and unsolved exercises are included within the text - and not separated at the end of chapters - for better understanding, training and application. Simulated results and their graphical plots are developed through MATLAB/Simulink code.

Book Synopsis Spacecraft Systems Engineering by : Cezar Dalca
Download or read book Spacecraft Systems Engineering written by Cezar Dalca and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems engineering is an interdisciplinary field of engineering that emphasises on how to design and manage multifaceted engineering systems over their life cycles. Systems engineering techniques are used in complex projects, such as spacecraft design, computer chip design, robotics, software integration, and bridge building. Systems engineering uses a host of tools that involves modelling and simulation, requirements analysis and scheduling to manage complexity. Traditional systems engineering was seen as a branch of engineering in the classical sense, i.e., as applied only to physical system, such as space craft and aircraft. More recently, systems engineering has developed to a take on a broader meaning exclusively when humans were seen as an essential component of a system. Systems concentrates on analysing and eliciting customer needs and required functionality early in the development cycle, documenting requirements, then proceeding with design synthesis and system validation while considering the complete problem, the system lifecycle. This book, Spacecraft Systems Engineering, offers the reader with inclusive coverage of the design of spacecraft and the implementation of space missions, with a wide spectrum of space applications and space science. This embraces mechanical, electrical and thermal aspects, as well as propulsion and control. This book is valuable for aerospace engineering students, and all those involved in the technical aspects of design and engineering in the space sector.
