<p><i>Motion Coordination for VTOL Unmanned Aerial Vehicles </i>develops new control design techniques for the distributed coordination of a team of autonomous unmanned aerial vehicles. In particular, it provides new control design approaches for the attitude synchronization of a formation of rigid body systems. In addition, by integrating new control design techniques with some concepts from nonlinear control theory and multi-agent systems, it presents a new theoretical framework for the formation control of a class of under-actuated aerial vehicles capable of vertical take-off and landing. Several practical problems related to the systems’ inputs, states measurements, and restrictions on the interconnection topology between the aerial vehicles in the team are addressed. Worked examples with sufficient details and simulation results are provided to illustrate the applicability and effectiveness of the theoretical results discussed in the book.</p> <p>The material presented is primarily intended for researchers and industrial engineers from robotics, control engineering and aerospace communities. It also serves as a complementary reading for graduate students involved in research related to flying robotics, aerospace, control of under-actuated systems, and nonlinear control theory</p>

At the end of World War II, as Allied forces uncovered the full horror of Nazi atrocities, the United States government made a calculated decision: recruit the scientists who had built Hitler's war machine. Under Operation Paperclip, more than 1,600 German engineers, physicists, and aerospace specialists were brought to America—their records sanitized, their pasts obscured, their expertise deemed too valuable to surrender to the Soviets. This book reconstructs that decision through declassified military and intelligence documents, State Department correspondence, survivor testimony from concentration camp laborers, and the personal records of the scientists themselves. It examines how Wernher von Braun and his colleagues transitioned from designing V-2 rockets built by forced labor at Mittelwerk to leading NASA's most celebrated programs, including the Saturn V rocket that carried Americans to the moon. The narrative does not reduce these men to simple villains or heroes. Instead, it interrogates the institutional logic that made Paperclip possible—the Cold War calculus that placed technological advantage above justice, the bureaucratic processes that erased criminal records, and the survivors of Nazi labor camps who spent decades demanding acknowledgment that was never fully given. A carefully documented account of how national interest and moral accountability collided in postwar America, and what that collision cost.

From theory and fundamentals to the latest advances incomputational and experimental modal analysis, this is thedefinitive, updated reference on structural dynamics. This edition updates Professor Craig's classic introduction tostructural dynamics, which has been an invaluable resource forpracticing engineers and a textbook for undergraduate and graduatecourses in vibrations and/or structural dynamics. Along withcomprehensive coverage of structural dynamics fundamentals,finite-element-based computational methods, and dynamic testingmethods, this Second Edition includes new and expanded coverage ofcomputational methods, as well as introductions to more advancedtopics, including experimental modal analysis and "activestructures." With a systematic approach, it presents solutiontechniques that apply to various engineering disciplines. Itdiscusses single degree-of-freedom (SDOF) systems, multipledegrees-of-freedom (MDOF) systems, and continuous systems in depth;and includes numeric evaluation of modes and frequency of MDOFsystems; direct integration methods for dynamic response of SDOFsystems and MDOF systems; and component mode synthesis. Numerous illustrative examples help engineers apply the techniquesand methods to challenges they face in the real world. MATLAB(r) isextensively used throughout the book, and many of the .m-files aremade available on the book's Web site. Fundamentals of StructuralDynamics, Second Edition is an indispensable reference and"refresher course" for engineering professionals; and a textbookfor seniors or graduate students in mechanical engineering, civilengineering, engineering mechanics, or aerospace engineering.

Thorough coverage of space flight topics with self-contained chapters serving a variety of courses in orbital mechanics, spacecraft dynamics, and astronautics This concise yet comprehensive book on space flight dynamics addresses all phases of a space mission: getting to space (launch trajectories), satellite motion in space (orbital motion, orbit transfers, attitude dynamics), and returning from space (entry flight mechanics). It focuses on orbital mechanics with emphasis on two-body motion, orbit determination, and orbital maneuvers with applications in Earth-centered missions and interplanetary missions. Space Flight Dynamics presents wide-ranging information on a host of topics not always covered in competing books. It discusses relative motion, entry flight mechanics, low-thrust transfers, rocket propulsion fundamentals, attitude dynamics, and attitude control. The book is filled with illustrated concepts and real-world examples drawn from the space industry. Additionally, the book includes a "computational toolbox" composed of MATLAB M-files for performing space mission analysis. Key features: * Provides practical, real-world examples illustrating key concepts throughout the book * Accompanied by a website containing MATLAB M-files for conducting space mission analysis * Presents numerous space flight topics absent in competing titles Space Flight Dynamics is a welcome addition to the field, ideally suited for upper-level undergraduate and graduate students studying aerospace engineering.

Why do highly educated teams of engineers and executives consistently ignore glaring safety flaws until a catastrophe strikes? The answer lies in a chilling sociological phenomenon called the normalization of deviance. When a rule is bent without an immediate negative consequence, the deviation slowly becomes the new acceptable standard, blinding entire organizations to impending doom. This investigative book dissects the invisible psychological shifts that lead to monumental failures, from aerospace tragedies to deepwater drilling blowouts. It reveals how the pressure to cut costs and meet deadlines slowly erodes safety cultures. The narrative illustrates that these disasters are rarely the result of sudden negligence, but rather a long, creeping acceptance of small anomalies that gradually numb a team's perception of risk. By understanding the mechanics of how deviance becomes normalized, leaders can overhaul their operational frameworks. Learn how to spot the early warning signs of systemic decay, empower whistleblowers, and establish unbending baselines of safety to protect your organization from its own complacency.

This book is available as Book on Demand. Over the past decade, many companies in the semiconductor and aerospace industries have significantly upgraded their new product development processes, with disciplined timelines, strict design reviews, 'gates' to decision making and cross-functional collaboration. Some companies are outperforming their industry peers in terms of time-to-market and meeting customer needs. This raises the question of how companies can achieve and sustain performance based on the new product development function. To answer this question the present book analyzes the new product development process with a focus on the underlying dynamic capabilities, how such routines evolve on different organizational levels, and what are the associated social phenomena. Comparative case study evidence suggests that higher order resource reconfiguration and integration routines are established idiosyncratically. It is argued that simple, perception-based and loosely-coupled routines seem to be more effective for reconfiguring responsibilities and task sequences. On the other hand, detailed, codified and rigid higher-order routines were found more effective for integrating personnel, outsourced services and new technology.
