This volume presents a materials research agenda for the commercial aircraft and automobile industries for the next two decades. Two case studies are used as a basis for discussion: the 50-mile-per-gallon, 5-passenger sedan and the high-speed civil transport. Also identified are those general materials drivers and the materials research required for each field.
Vehicle weight reduction is an effective strategy for reducing fuel consumption in civilian vehicles. For combat vehicles, it presents not only an important opportunity to reduce fuel use and associated logistics, but also important advantages in transport and mobility on the battlefield. Although there have been numerous efforts in the past to reduce the overall weight of combat vehicles, combat vehicle weight has continued to increase over time due to new threats and missions. On December 8 and 9, 2014, the National Academies of Sciences, Engineering, and Medicine held a workshop to explore opportunities in lightweight materials for armored vehicles. This was the ninth workshop in an ongoing series for the U.S. military on materials and manufacturing issues. The workshop discussed future advances in weight reduction by materials substitution for vehicles, including such topics as armor, structure, automotive parts, and armaments. This publication summarizes the presentations and discussions from the workshop.
In order to achieve the Army's envisioned Objective Force related to deployability, transportability, and mobility, the Committee on Lightweight Materials for the 21st Century Army Trucks was asked to identify research and technology development opportunities related to the introduction of new lightweight structural materials for light medium and heavy Army trucks.
The period between 1867 and 1914 remains the greatest watershed in human history since the emergence of settled agricultural societies: the time when an expansive civilization based on synergy of fuels, science, and technical innovation was born. At its beginnings in the 1870s were dynamite, the telephone, photographic film, and the first light bulbs. Its peak decade - the astonishing 1880s - brought electricity - generating plants, electric motors, steam turbines, the gramophone, cars, aluminum production, air-filled rubber tires, and prestressed concrete. And its post-1900 period saw the first airplanes, tractors, radio signals and plastics, neon lights and assembly line production. This book is a systematic interdisciplinary account of the history of this outpouring of European and American intellect and of its truly epochal consequences. It takes a close look at four fundamental classes of these epoch-making innovations: formation, diffusion, and standardization of electric systems; invention and rapid adoption of internal combustion engines; the unprecedented pace of new chemical syntheses and material substitutions; and the birth of a new information age. These chapters are followed by an evaluation of the lasting impact these advances had on the 20th century, that is, the creation of high-energy societies engaged in mass production aimed at improving standards of living.
This study assesses the potential of new technology to reduce logistics support requirements for future Army combat systems. It describes and recommends areas of research and technology development in which the Army should invest now to field systems that will reduce logistics burdens and provide desired capabilities for an ''Army After Next (AAN) battle force" in 2025.
