Available in PDF, EPUB and Kindle. Book excerpt: The advent of commercial launch systems has brought about a new age of space launch vehicle design. In order to survive in a competitive market, space launch providers must design systems with new technologies in shorter development times. This changing nature of space launch vehicle design requires a new way to perform safety analysis. Traditional hazard analysis techniques do not deliver adequate insight early in the design process, when most of the safety-related decisions are made. Early design decisions are often made using "lessons-learned" from previous launch systems, rather than interactive feedback from the new vehicle design actually being developed. Furthermore, traditional techniques use reliability theory as their foundation, resulting in the use of excessive design margin and redundancy as the "default" vehicle design choices. This equivocation of safety and reliability may have made sense for simpler launch vehicles of the past, but most modern space launch vehicle accidents have resulted from incorrect software specifications, component interaction accidents, and other design errors independent of the reliability of individual components. The space launch industry needs safety analysis methods and design processes that identify and correct these hazards early in the vehicle design process, when modifications to correct safety issues are more effective and less costly. This work shows how Systems-Theoretic Process Analysis (STPA) can been used as a powerful tool to identify, mitigate, and possibly eliminate hazards throughout the entire space launch vehicle lifecycle. This work begins by reviewing traditional hazard analysis techniques and the changing nature of launch vehicle accidents. Next, it describes how STPA can be integrated into the space launch vehicle lifecycle to design safer systems. It then demonstrates the safety-guided design of a small-lift launch vehicle using STPA. Finally, this work shows how STPA can be used to satisfy regulatory and range safety requirements. The thesis of this work is that integration of STPA into the design of space launch vehicles can make a significant contribution to reducing launch vehicle accidents.

Download or read book Safety Design for Space Systems written by Tommaso Sgobba and published by Elsevier. This book was released on 2023-07-25 with total page 1190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lack of widespread education in space safety engineering and management has profound effects on project team effectiveness in integrating safety during design. On one side, it slows down the professional development of junior safety engineers, while on the other side it creates a sectarian attitude that isolates safety engineers from the rest of the project team. To speed up professional development, bridge the gap within the team, and prevent hampered communication and missed feedback, the entire project team needs to acquire and develop a shared culture of space safety principles and techniques.The second edition of Safety Design for Space Systems continues to address these issues with substantial updates to chapters such as battery safety, life support systems, robotic systems safety, and fire safety.

Available in PDF, EPUB and Kindle. Book excerpt: A hazard analysis for the test firing of NASA's Space Launch System core stage is performed using a systems-based alternative to the traditional reliability-based method. The method used, Systems-Theoretic Process Analysis (STPA), is shown to be a versatile and powerful tool in this application and by extension the development of future space launch vehicles. The Boeing Company has been selected by NASA as the prime contractor for the Space Launch System (SLS) cryogenic stages. As such, they are working with NASA to develop a comprehensive hazard analysis for core stage test firing and eventual launch operations. Developing, testing, and launching rockets is an inherently complex and high risk endeavor. Preceding the launch itself, one of the highest risk times in the operation of a rocket is the static fire testing, also called a hot fire. Hundreds of parameters need to be monitored in real time in order to ensure the system is operating nominally and equipment damage (and possible injury or death) will not occur. Depending on the point of the testing and the resultant speed at which events are occurring, different levels of automatic safing conditions and operator actions are required to protect the vehicle. Traditionally, the way these safing conditions are derived is through the evaluation of hazard reports, which are themselves based on a "reliability" model: hazards are seen to arise from the failure of individual components and are thus primarily mitigated through increasing component reliability or adding in redundancy. With the level of complexity and required safety of today's launch systems, it is beneficial to evaluate a new approach to identifying the underlying hazards in a system, including ones that arise from unsafe component interactions and not simply failures

Available in PDF, EPUB and Kindle. Book excerpt: Chapter 5 extends the launch safety analysis to toxic and distant focusing overpressure hazards. A major section of this chapter is devoted to each of these hazards. Rocket motor propellants and their combustion products may pose toxic hazards in the extended launch vicinity. Moreover, accidental explosions on or near a launch pad may, with adverse atmospheric conditions, cause explosive shock waves to break windows at distant population centers potentially threatening their occupants. Currently, liquid propellants may be hazardous; however, their combustion products are not. Solid propellants, by contrast, do not directly pose a toxic hazard; their combustion products are, however, frequently hazardous. The chapter introduces the reader to each of the hazards, characterizing the source term, factors governing the propagation of the hazards to people, and guidelines for evaluating the severity of the hazardous conditions that may exist at population centers. Comprehensive modeling of these two hazards is complex. Consequently, for each hazard one or more screening methodologies is presented to allow scoping studies to be performed to assess if there is a need for more comprehensive modeling. Each section then presents a comprehensive discussion of the analysis of the threat and the risk posed by the two hazards so that the reader understands how the complete analyses must be performed.

This book was released on 2000-04-15 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. space program is rapidly changing from an activity driven by federal government launches to one driven by commercial launches. In 1997, for the first time commercial launches outnumbered government launches at the Eastern Range (ER), located at Cape Canaveral Air Station, Florida. Commercial activity is also increasing at the Western Range (WR), located at Vandenberg Air Force Base, California. The government itself is emulating commercial customers, shifting from direct management of launch programs to the purchase of space launch services from U.S. commercial launch companies in an open, competitive market. The fundamental goal of the U.S. space program is to ensure safe, reliable, and affordable access to space. Despite the inherent danger of space launches, the U.S. space program has demonstrated its ability to protect the public. No launch site worker or member of the general public has been killed or seriously injured in any of the 4,600 launches conducted at the ER and WR during the entire 50-year history of the space age. Streamlining Space Launch Range Safety discusses whether range safety processes can be made more efficient and less costly without compromising public safety. This report presents six primary recommendations, which address risk management, Africa gates, roles and responsibilities, range safety documentation [EWR 127-1]), global positioning system (GPS) receiver tracking systems, and risk standards for aircraft and ships.

Download or read book Safety Guided Design Analysis in Multi purposed Japanese Unmanned Transfer Vehicle written by Ryo Ujiie and published by . This book was released on 2016 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with other critical systems, space systems are also getting larger and more complex. Although Japan Aerospace Exploration Agency (JAXA) has designed various spacecraft and had not experienced any serious accident for more than 10 years, loss of an astronomical satellite finally happened in 2016 even though the development process was not drastically different from the past. The accident implies that the complexity of space systems can no longer be managed by the traditional safety analysis. Furthermore, in huge system developments, the fluidity of design is rapidly lost as the development proceeds. Thus, creating a safer system design in the early development phase that is capable of handling various undesirable scenarios will significantly contribute to the success of huge and complex system development. The goal of this thesis is to establish the way to design a safer system in the context of modern huge and complex systems and demonstrate its effectiveness in an actual JAXA future transfer vehicle design. As a solution, in this thesis a new accident model called System Theoretic Accident Model and Process (STAMP) is used. The safety analysis methods based on STAMP were invented to handle the characteristics of modem complex systems. Furthermore, detailed designs are not required in the analysis. Therefore, the issues of modern complex systems are expected to be solved by the system theoretic safety design methods. In this thesis, two types of system analysis were conducted based on STAMP: concept design analysis in the target system and incident analysis in a similar previous system. While any detailed specification was not available, various unsafe off-nominal system behaviors were derived from the concept design, and it was refined. Remarkably, off-nominal behaviors due to a new design policy being applied in the system were successfully described. Furthermore, various design flaws involving human-automation interactions were also found, which usually tends to be discussed in the later development phase. The result indicates the proposed system theoretic safety design approaches can be successfully interwoven with the early stage of development process, and systems can be fundamentally refined from a safety perspective to prevent future serious losses.

Available in PDF, EPUB and Kindle. Book excerpt: This chapter provides a guideline for managing third party risks generated by the launch of a space booster. First it defines the hazardous conditions necessary for risk to be present, exposure of people or assets to the hazards, and the vulnerability of people or assets to the hazardous conditions. This provides the structure for how to control risks. Commonly used risk measures are defined. The discussion then turns to the implementation of risk and hazard controls including defining exclusion regions based on prelaunch analyses to protect populations and defining real-time range safety systems for limiting the risk during an operation. The remainder of the chapter is devoted to the flight safety analysis process with an emphasis on debris risk analysis, and includes both highly simplified models for rapid risk estimation and more sophisticated models.

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

Download or read book Commercial Satellite Launch Vehicle Attitude Control Systems Design and Analysis H infinity Loop Shaping and Coprime Approach written by Chong Hun Kim and published by Lulu.com. This book was released on 2007 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for aerospace engineers who have completed their BS degree and are interested in the design and analysis of rocket attitude control systems. It introduces a new approach to the design, characterized by its robustness. Current LV attitude control systems are designed based on classical SISO control theory, and they lack robustness. The theory used here truly offers a technique that enables us to design control systems that are reasonably insensitive to math modeling errors and can withstand disturbances such as gust, and in addition it doesn’t need external states estimator, such as Kalman filtering. Extensive simulation results, which demonstrate the effectiveness of this approach, are presented in this book. Basic rocket theory and a concept of H-infinity control system design technique are explained for those who are new in these fields of study.
