Available in PDF, EPUB and Kindle. Book excerpt: At its inception, three major goals were established for this contract effort. First, define promising directions for structural research by applying the concept of minimum cost rather than maximum performance to structural design. Second, understand the relationship of structure to the economics of the total system. Third, identify and apply the interactions of the various aspects of program costs to point out the potential cost savings they imply. The material presented in this report shows that these goals have been satisfied. A number of structural research areas have been identified. These are developed individually throughout this document and are collected in this section for visibility. An understanding of the system role played by structure has been developed in five system studies that show, in general, that structure, when considered as a subsystem, is unique in its far-reaching effect on the system. Moreover, detailed consideration of other subsystems reveals a large structural influence. Finally, strong interactions of structural design decisions with aerospace system costs have been demonstrated, particularly by the study described in Section 4.5, and significant potential cost savings have been identified.

Available in PDF, EPUB and Kindle. Book excerpt: Reducing Space Mission Cost is the first complete treatment of the technology, process, and problems in the most critical areas of modern spaceflight. The demand to reduce cost is unrelenting. This pioneering book addresses all aspects of this problem, including: Technology and processes for reducing cost Cost reduction in mission engineering, spacecraft design, manufacture, launch, and operations Implementation methods and problems The price of reducing cost 10 detailed case studies of what works in practice in: Science missions Interplanetary probes Communications spacecraft Test and Applications missions Beginning on the inside front cover, this book provides real cost data on a variety of missions, systems, and subsystems. According to the authors: `Reducing mission cost is hard enough if you know what the real costs are, and virtually impossible if you don't.' This book challenges traditional methods, yet recognizes that all space programs are run to minimize cost within the rules under which they are built and flown. It provides practical recipes for reducing cost in both new and ongoing missions and discusses what works, what government can do to help, and what methods intended to reduce cost may be counterproductive and unintentionally increase cost. As shown on the inside rear cover, the case studies described in the book have reduced total mission cost by 80% to more than 90% with respect to projections by traditional cost methods. This book is a follow-on to the now standard text and reference, Space Mission Analysis and Design, also edited by Drs. Wertz and Larson. It is required reading for professionals, students, and managers in astronautics or space sciences and managers or scientists involved in space experiments. This book shows that reducing space mission cost, without reducing reliability, is as possible as it is important for the future of space exploration.

This book was released on 2018-07-17 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of commonality in a system represents an attempt to reduce costs by reducing the number of unique components. A formal method for conducting commonality analysis has not been established. In this dissertation, commonality analysis is characterized as a partitioning problem. The cost impacts of commonality are quantified in an objective function, and the solution is that partition which minimizes this objective function. Clustering techniques are used to approximate a solution, and sufficient conditions are developed which can be used to verify the optimality of the solution. This method for commonality analysis is general in scope. It may be applied to the various types of commonality analysis required in the conceptual, preliminary, and detail design phases of the system development cycle.

Available in PDF, EPUB and Kindle. Book excerpt: (cont.) The three NASA case studies showed that two trends that were consistently observed in the industry cases (life cycle offsets and divergence) also exist within NASA systems. In addition, the management approaches were observed to be common between NASA and industry. In conducting the NASA case studies, several management methods were identified that can encourage the successful application of commonality, including: the organizational structure, the level of management support, the type of contract, and design competencies. Each of the observed management methods are discussed in the thesis within the scope of the individual case study and in the broader scope of all three systems in the cross-case analysis. In each of the three NASA case studies and seven industry case studies, it was observed that the evaluation of commonality was often either overlooked or reduced to notional or qualitative analysis. To address this problem, both a deterministic economic cost model and an economic cost model that evaluates commonality as a Real Option were developed to better evaluate the systems. Evaluating commonality as a Real Option allows management to consider uncertainties and flexibility in the system. Both methods of evaluating opportunities for commonality are applied using information from the CSSS case study as an example.
Download or read book Reducing Risk of Large Scale Space Systems Using a Modular Architecture written by and published by . This book was released on 2004 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future requirements may dictate the need for very large spacecraft architectures. At present, the only approach to placing large spacecraft into orbit is use of a heavy lift launch vehicle. But, given the new capabilities demonstrated by NASA's DART, and DARPA's Orbital Express, RASCAL, and FALCON, it is reasonable to envision an alternative means of placing large spacecraft into orbit, that being multiple responsive launches of discrete modules which are later assembled on orbit. An analysis was performed to compare the risks and benefits of single large spacecraft launch versus a multiple small module launch approach. The results of this probabilistic analysis show that fragmenting a system into modules can significantly reduce the deleterious cost and schedule impact incurred by possible failures. In short, a single launch of a monolithic spacecraft poses significant risk; should failure of a large spacecraft launch occur, the penalty is the significant sum total of both launch and spacecraft costs.
Download or read book Commonality of Ground Systems in Launch Operations written by Shawn M. Quinn and published by . This book was released on 2008 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA is examining the utility of requiring a certain degree of commonality in both flight and ground systems in the Constellation Program. While the benefits of commonality seem obvious in terms of minimizing upfront development and long-term operations and maintenance costs, success in real, large-scale engineering systems used to support launch operations is relatively unknown. A broad literature review conducted for this paper did not yield a single paper specifically addressing the application of commonality for ground systems at any launch site in the United States or abroad. This paper provides a broad overview of the ground systems, captures historical and current application of commonality at the launch site, and offers suggestions for additional research to further develop commonality approaches.

Available in PDF, EPUB and Kindle. Book excerpt: The definition of all space systems starts with the establishment of its fundamental parameters: requirements to be fulfilled, overall system and satellite design, analysis and design of the critical elements, developmental approach, cost, and schedule. There are only a few texts covering early design of space systems and none of them has been specifically dedicated to it. Furthermore all existing space engineering books concentrate on analysis. None of them deal with space system synthesis – with the interrelations between all the elements of the space system. Introduction to Space Systems concentrates on understanding the interaction between all the forces, both technical and non-technical, which influence the definition of a space system. This book refers to the entire system: space and ground segments, mission objectives as well as to cost, risk, and mission success probabilities. Introduction to Space Systems is divided into two parts. The first part analyzes the process of space system design in an abstract way. The second part of the book focuses on concrete aspects of the space system design process. It concentrates on interactions between design decisions and uses past design examples to illustrate these interactions. The idea is for the reader to acquire a good insight in what is a good design by analyzing these past designs.
