There have been increasing reports of annoyance, fatigue, and even neck and back pain during prolonged operation of military propeller aircraft, where persistent multi-axis vibration occurs at higher frequencies beyond human whole-body resonance. This paper characterizes and assesses the higher frequency vibration transmitted to the occupants onboard four aircraft: the WC-130J, C-130J, C-130H3, and E-2C.
There have been increasing complaints of annoyance, fatigue, and musculoskeletal pain during prolonged exposures to propulsion-generated vibration in military propeller aircraft. The objective of this study was to evaluate the effects of seat cushions on mitigating the higher frequency (>10 Hz) multi-axis vibration associated with Navy E-2C Hawkeye operations. An E-2C crew seat was used in the laboratory during exposure to a selected operational signal. Triaxial accelerations were measured at the interface between the human and cushion (seat pan and seat back). The most pronounced effects were observed at the blade passage frequency ( -73.5 Hz). The highest vibration occurred at the seat pan in the fore-and-aft (X) direction of the subject (lateral direction of the aircraft). Substantial vibration was observed at the seat back in the vertical (Z) direction. Significantly lower levels of fore-and-aft (X) vibration occurred at the seat pan with all cushions as compared to the original E-2C cushion (P
Encompassing all occupants of aircraft and spacecraft—passengers and crew, military and civilian—Fundamentals of Aerospace Medicine, 5th Edition, addresses all medical and public health issues involved in this unique medical specialty. Comprehensive coverage includes everything from human physiology under flight conditions to the impact of the aviation industry on public health, from an increasingly mobile global populace to numerous clinical specialty considerations, including a variety of common diseases and risks emanating from the aerospace environment. This text is an invaluable reference for all students and practitioners who engage in aeromedical clinical practice, engineering, education, research, mission planning, population health, and operational support.
This volume covers the various sensors related to automotive and aerospace sectors, discussing their properties as well as how they are realized, calibrated and deployed. Written by experts in the field, it provides a ready reference to product developers, researchers and students working on sensor design and fabrication, and provides perspective on both current and future research.
This book gathers the proceedings of the Multidisciplinary International Conference of Research Applied to Defense and Security (MICRADS), held at the Eloy Alfaro Military Academy (ESMIL) in Quito, Ecuador, on May 13–15,2020. It covers a broad range of topics in systems, communication, and defense; strategy and political–administrative vision in defense; and engineering and technologies applied to defense. Given its scope, it offers a valuable resource for practitioners, researchers, and students alike.
Recently, there have been a number of advances in technology, including in mobile devices, globalization of companies, display technologies and healthcare, all of which require significant input and evaluation from human factors specialists. Accordingly, this textbook has been completely updated, with some chapters folded into other chapters and new chapters added where needed. The text continues to fill the need for a textbook that bridges the gap between the conceptual and empirical foundations of the field.
Bill Ragan, M.S. said that circadian desynchronization was one of the causes of several aircraft accidents over the years. While the exact cause of these accidents was hard to pinpoint, many of them were linked to human error. Lag: A Look at Circadian Desynchronization (ISBN 978-1-4357-0221-9) was focused on stress that resulted from jet lag, shift work, and fatigue in aviation. Many of the principles included here transfer over to other industries like commercial overland transportation, law enforcement, and healthcare. How much does fatigue cost you? Only the reader will know, but factors that can influence the costs were discussed in this book. Not intended to be a substitute for a consultation by a provider, some interventions intended to help lower the cost of fatigue were included, as well.
In terms of simple and complex systems, it is a whole new world out there. At the initial publication of this book, fourteen years ago, the web was in its infancy, DVDs did not exist, cell phones were few and far between, and the information superhighway was just a blip upon the horizon. If you used the terms "social engineering," you were most likely a political scientist, and if you were "phishing" you might be listening to a rock band. The second edition of a bestseller, Human Factors in Simple and Complex Systems provides the necessary understanding of the breadth and depth of human factors issues that influence the design, implementation, and evaluation of products and systems. Emphasizing the close relationship between basic theory and application, the authors delineate a framework for the research process, present an integrated view of the current state of knowledge, and examine how these factors can be applied to system design. The new edition addresses such concepts as situation awareness and highlights topics of interest, with a special focus on computer applications and human-computer interaction. See what’s new in the Second Edition New topics, such as situational awareness, that capture the tremendous changes in human factors and ergonomics Tightly integrates basic research and application, strengthening the link between knowledge and practice Each chapter includes a separate box that discusses a topic of current interest related to human interaction with computers and recent technology Demonstrating a general approach to solving a broad range of system problems, the book provides coverage of the theoretical foundation on which the discipline of human factors is built. Structured around human information processing, it covers the full range of contemporary human factors and ergonomics, then shows you how to apply them.
Now in its Fourth Edition with a new editorial team, this comprehensive text addresses all medical and public health issues involved in the care of crews, passengers, and support personnel of aircraft and space vehicles. Coverage includes human physiology under flight conditions, clinical medicine in the aerospace environment, and the impact of the aviation industry on global public health. This edition features new chapters on radiation, toxicology and microbiology, dental considerations in aerospace medicine, women's health issues, commercial human space flight, space exploration, and unique aircraft including parachuting. Other highlights include significant new information on respiratory diseases, cardiovascular medicine, infectious disease transmission, and human response to acceleration.
