This book was released on 2005 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protective helmets are typically required to absorb energy in order to reduce head injury risk during blunt impact events. The energy-absorbing mechanism must be robust enough to reduce the impact energy to a low-injury probability level throughout a realistic range of impact velocities and environmental temperatures, regardless of the helmet impact site. The Advanced Combat Helmet (ACH) is configured with fitting pads that possess the capability to attenuate limited blunt head impact forces. Prior combat helmets were not required by their governing specifications to provide any tested levels of blunt impact protection. to obtain further information, a series of blunt impact tests were conducted with the ACH and the paratrooper and infantry versions of the PASGT helmet. The helmets were tested at two impact velocities, three environmental temperatures, and seven impact sites with two successive impacts. The performance of each was characterized by the transmitted acceleration measured within a standard head form and compared against the recommended threshold for mean and maximum acceleration.

Book Synopsis Review of Department of Defense Test Protocols for Combat Helmets by : National Research Council
Download or read book Review of Department of Defense Test Protocols for Combat Helmets written by National Research Council and published by National Academies Press. This book was released on 2014-03-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combat helmets have evolved considerably over the years from those used in World War I to today's Advanced Combat Helmet. One of the key advances was the development of aramid fibers in the 1960s, which led to today's Kevlar-based helmets. The Department of Defense is continuing to invest in research to improve helmet performance, through better design and materials as well as better manufacturing processes. Review of the Department of Defense Test Protocols for Combat Helmets considers the technical issues relating to test protocols for military combat helmets. At the request of the DOD Director of Operational Test and Evaluation, this report evaluates the adequacy of the Advanced Combat Helmet test protocol for both first article testing and lot acceptance testing, including its use of the metrics of probability of no penetration and the upper tolerance limit (used to evaluate backface deformation). The report evaluates appropriate use of statistical techniques in gathering data; adequacy of current helmet testing procedures; procedures for the conduct of additional analysis of penetration and backface deformation data; and scope of characterization testing relative to the benefit of the information obtained.

Book Synopsis The Effects of the Personal Armor System for Ground Troops (PASGT) and the Advanced Combat Helmet (ACH) with and Without PVS-14 Night Vision Goggles (NVG) on Neck Biomechanics During Dismounted Soldier Movements by :
Download or read book The Effects of the Personal Armor System for Ground Troops (PASGT) and the Advanced Combat Helmet (ACH) with and Without PVS-14 Night Vision Goggles (NVG) on Neck Biomechanics During Dismounted Soldier Movements written by and published by . This book was released on 2007 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kevlar helmets provide the soldier with basic ballistic and impact protection. However, the helmet has recently become a mounting platform for devices such as night-vision goggles, drop down displays, weapon-aiming systems, etc. Although designed to enhance soldier performance, these systems increase the mass of the helmet and typically shift the position of the helmet's center of mass forward. The effects of changing the mass properties of the helmet on head and neck forces and moment on neck muscle activity and fatigue are well documented for aviators and soldiers in vehicles. No research to date has been focused on the effects of helmets of varying mass and mass distribution on head and neck forces and moments during a combat foot soldier's physical activities. Physical demands on the combat foot soldier are substantially different from those on aviator or soldiers in vehicles. Therefore, changing the mass properties of the helmet likely has different effects on combat foot soldiers than on aviators. The study answers the militarily relevant question of what forces and moments on the head and neck are associated with currently used Army helmets and night vision goggles during combat physical activities of the ground soldier.
Book Synopsis Gulf War and Health by : Institute of Medicine
Download or read book Gulf War and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2014-04-14 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the United States began combat operations in Afghanistan in October 2001 and then in Iraq in March 2003, the numbers of US soldiers killed exceed 6,700 and of US soldiers wounded 50,500. Although all wars since World War I have involved the use of explosives by the enemy, the wars in Afghanistan and Iraq differ from previous wars in which the United States has been involved because of the enemy's use of improvised explosive devices (IEDs). The use of IEDs has led to an injury landscape different from that in prior US wars. The signature injury of the Afghanistan and Iraq wars is blast injury. Numerous US soldiers have returned home with devastating blast injuries and they continue to experience many challenges in readjusting to civilian life. Gulf War and Health, Volume 9 is an assessment of the relevant scientific information and draws conclusions regarding the strength of the evidence of an association between exposure to blast and health effects. The report also includes recommendations for research most likely to provide VA with knowledge that can be used to inform decisions on how to prevent blast injuries, how to diagnose them effectively, and how to manage, treat, and rehabilitate victims of battlefield traumas in the immediate aftermath of a blast and in the long term.

Book Synopsis Finite Element Modeling and Simulation of a Full-size Combat Helmet Under Ballistic and Blunt Impacts by : Emre Palta
Download or read book Finite Element Modeling and Simulation of a Full-size Combat Helmet Under Ballistic and Blunt Impacts written by Emre Palta and published by . This book was released on 2014 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this thesis was to use finite element (FE) modeling and simulations to study the performance of the Advanced Combat helmet (ACH) that is currently used by the U.S. military. In this research, nonlinear FE simulations were performed using LS-DYNA to evaluate the ACH responses under both high-speed (i.e. ballistic) and low-speed (i.e. blunt) impacts. To compare with experimental data under identical conditions, the pad system of ACH and two different headforms were modeled and used in the simulations. The ACH model was first validated using test data provided by manufacturer, which were conducted to fulfil requirements of NIJ-0106.01 standards and V5o ballistic limit evaluation. The validated model was then used to assess the ACH responses under blunt impacts (drop test) at five impact locations and two different speeds (i.e., 10 fps and 14 fps). Finally, the validated ACH model was used in the simulations of ballistic impacts of 9 mm and .223 bullets. The comparison of simulation results to experimental data showed that the ACH model developed in this study was capable of predicting the ACH responses under ballistic and blunt impacts with reasonably good accuracy. The work in this thesis demonstrated the advantages and usefulness of FE modeling and simulations to body armor applications.

Download or read book Hybridized Thermoplastic Aramids: Enabling Material Technology For Future Force Headgear written by and published by . This book was released on 2006 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Army ballistic helmet manufacturing has not changed significantly in nearly 30 years. Advances in U.S. helmet technology have been largely in shell design, improved aramid fibers, and helmet liner and suspension systems. The Army is currently replacing its first composite ballistic helmet, Personnel Armor System Ground Troops (PASGT), with the Advanced Combat Helmet (ACH). ACH has undergone ballistic testing and system analysis with improvements to weapons and body armor interfacing issues. Still, ACH uses some of the same materials (butyl rubber toughened phenolic resin with aramid fabric reinforcements) and the same process technology as its 30 year old PASGT predecessor. The current research effort has focused on identifying and resolving technology barriers that limit a new and improved generation of ballistic materials from being considered for use in future helmet systems. Both historical and contemporary perspectives of ballistic helmet technology are provided as rationale for the development of alternative helmet materials and their associated processes. The primary technology barriers are four-fold: structural durability (static and dynamic deformation), contiguous preform construction (less cutting of the reinforcement without wrinkling), hybridization of dissimilar fibers and resins, and low cost manufacturing (rapid heating, consolidation, and cooling of tools and parts). Flat plates and full helmet shells were molded to quantify the performance and benefits of hybridized materials to meet current and future demands for increased ballistic mass efficiency.
Book Synopsis The Russian Way of War by : Lester W. Grau
Download or read book The Russian Way of War written by Lester W. Grau and published by Mentor Military. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force Structure, Tactics, and Modernization of the Russian Ground Forces The mighty Soviet Army is no more. The feckless Russian Army that stumbled into Chechnya is no more. Today's Russian Army is modern, better manned, better equipped and designed for maneuver combat under nuclear-threatened conditions. This is your source for the tactics, equipment, force structure and theoretical underpinnings of a major Eurasian power. Here's what the experts are saying: "A superb baseline study for understanding how and why the modern Russian Army functions as it does. Essential for specialist and generalist alike." -Colonel (Ret) David M. Glantz, foremost Western author on the Soviet Union in World War II and Editor of The Journal of Slavic Military Studies. "Congratulations to Les Grau and Chuck Bartles on filling a gap which has yawned steadily wider since the end of the USSR. Their book addresses evolving Russian views on war, including the blurring of its nature and levels, and the consequent Russian approaches to the Ground Forces' force structuring, manning, equipping, and tactics. Confidence is conferred on the validity of their arguments and conclusions by copious footnoting, mostly from an impressive array of primary sources. It is this firm grounding in Russian military writings, coupled with the authors' understanding of war and the Russian way of thinking about it, that imparts such an authoritative tone to this impressive work." -Charles Dick, former Director of the Combat Studies Research Centre, Senior Fellow at the Defence Academy of the United Kingdom, author of the 1991 British Army Field Manual, Volume 2, A Treatise on Soviet Operational Art and author of From Victory to Stalemate The Western Front, Summer 1944 and From Defeat to Victory, The Eastern Front, Summer 1944. "Dr. Lester Grau's and Chuck Bartles' professional research on the Russian Armed Forces is widely read throughout the world and especially in Russia. Russia's Armed Forces have changed much since the large-scale reforms of 2008, which brought the Russian Army to the level of the world's other leading armies. The speed of reform combined with limited information about their core mechanisms represented a difficult challenge to the authors. They have done a great job and created a book which could be called an encyclopedia of the modern armed forces of Russia. They used their wisdom and talents to explore vital elements of the Russian military machine: the system of recruitment and training, structure of units of different levels, methods and tactics in defense and offence and even such little-known fields as the Arctic forces and the latest Russian combat robotics." -Dr. Vadim Kozyulin, Professor of Military Science and Project Director, Project on Asian Security, Emerging Technologies and Global Security Project PIR Center, Moscow. "Probably the best book on the Russian Armed Forces published in North America during the past ten years. A must read for all analysts and professionals following Russian affairs. A reliable account of the strong and weak aspects of the Russian Army. Provides the first look on what the Russian Ministry of Defense learned from best Western practices and then applied them on Russian soil." -Ruslan Pukhov, Director of the Moscow-based Centre for the Analysis of Strategies and Technologies (CAST) and member of the Public Council of the Russian Federation Ministry of Defense. Author of Brothers Armed: Military Aspects of the Crisis in Ukraine, Russia's New Army, and The Tanks of August.

Book Synopsis Deep Maneuver by : Jack D Kern Editor
Download or read book Deep Maneuver written by Jack D Kern Editor and published by Createspace Independent Publishing Platform. This book was released on 2018-10-12 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 5, Deep Maneuver: Historical Case Studies of Maneuver in Large-Scale Combat Operations, presents eleven case studies from World War II through Operation Iraqi Freedom focusing on deep maneuver in terms of time, space and purpose. Deep operations require boldness and audacity, and yet carry an element of risk of overextension - especially in light of the independent factors of geography and weather that are ever-present. As a result, the case studies address not only successes, but also failure and shortfalls that result when conducting deep operations. The final two chapters address these considerations for future Deep Maneuver.
