Available in PDF, EPUB and Kindle. Book excerpt: CSIS's The Future of Military Engines looks at the state of the U.S. military engine industrial base and the choices confronting policymakers at the Department of Defense (DoD). The military engine industrial base is closely tied to the industrial base for commercial engines. U.S. engine providers use many of the same facilities and largely the same supply chain for military and commercial engines. The ability to leverage commercial supply chains is critical because supply chain quality underlies the performance advantage of U.S. military engines, both for individual aircraft and military aircraft fleets. International competitors such as Russia and China are seeking to overtake the U.S. in engines. However, the current U.S. advantage is sustainable if it is treated as a national priority. Many military aircraft, especially fighters, require engines with important differences from commercial aircraft. They fly different flight profiles and perform different jobs. These differences mean that while DoD can leverage the commercial engine industrial base, it must also make investments to sustain the industrial base’s unique military components. In the next few years, DoD investment in military engines is projected to decrease significantly, particularly for R&D. This presents a challenge as military-unique engineering skills are highly perishable. Four major policy choices confront DoD as it formulates its investment approach to military engines going forward: 1) Priority, 2) Resources, 3) Business Model, and 4) Competition. The DoD is at an inflection point for engine investment, and the time for choosing on these four key policy questions will come in the next few years.
Download or read book Materials Needs and R D Strategy for Future Military Aerospace Propulsion Systems written by National Research Council and published by National Academies Press. This book was released on 2011-06-20 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing development of military aerospace platforms requires continuous technology advances in order to provide the nation's war fighters with the desired advantage. Significant advances in the performance and efficiency of jet and rocket propulsion systems are strongly dependent on the development of lighter more durable high-temperature materials. Materials development has been significantly reduced in the United States since the early 1990s, when the Department of Defense (DOD), the military services, and industry had very active materials development activities to underpin the development of new propulsion systems. This resulted in significant improvements in all engine characteristics and established the United States in global propulsion technology. Many of the significant advances in aircraft and rocket propulsion have been enabled by improved materials and, materials manufacturing processes. To improve efficiency further, engine weight must be reduced while preserving thrust. Materials Needs and Research and Development Strategy for Future Military Aerospace Propulsion Systems examines whether current and planned U.S. efforts are sufficient to meet U.S. military needs while keeping the U.S. on the leading edge of propulsion technology. This report considers mechanisms for the timely insertion of materials in propulsion systems and how these mechanisms might be improved, and describes the general elements of research and development strategies to develop materials for future military aerospace propulsion systems. The conclusions and recommendations asserted in this report will enhance the efficiency, level of effort, and impact of DOD materials development activities.

Book excerpt: To operate in the more stringent combat environments of the future, future propulsion systems will have to be more reliable, durable and maintainable. The development community has already responded with many initiatives to address the reliability and durability problems that became apparent during the 1970s. Consequently, the first half of this paper will discuss instead design features that may enhance maintainability and assess the extent to which they have been incorporated in existing engines. The second half of the paper assesses how demands for more supportable engines are influencing the amount of testing and the calendar time required to develop new engines for use in fighter and attack aircraft.

Download or read book Opposed Piston Engines written by Jean-Pierre Pirault and published by SAE International. This book was released on 2009-10-08 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the opposed piston (OP) engine, a model of power and simplicity, and provides the first comprehensive description of most opposed piston (OP) engines from 1887 to 2006. Design and performance details of the major types of OP engines in stationary, ground, marine, and aviation applications are explored and their evolution traced. The OP engine has set enviable and leading-edge standards for power/weight refinement, fuel tolerance, fuel efficiency, package space, and manufacturing simplicity. For these reasons, the OP concept still remains of interest for outstanding power and package density, simplicity, and reliability; e.g., aviation and certain military transport requirements. Using material from historic and unpublished internal research reports, the authors present the rationale for OP engines, their diverse architecture, detailed design aspects, performance data, manufacturing details, and leading engineers and applications. Comparisons to four-stroke and competitor engines are made, supporting the case for reconsidering OP engines for certain applications. Topics include: The history of OP engines Aeronautical Automotive Military Marine Unusual OP engines Comparison between 2 and 4 stroke engines The future of OP engines and more

Download or read book Force Multiplying Technologies for Logistics Support to Military Operations written by National Research Council and published by National Academies Press. This book was released on 2014-12-15 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mission of the United States Army is to fight and win our nation's wars by providing prompt, sustained land dominance across the full range of military operations and spectrum of conflict in support of combatant commanders. Accomplishing this mission rests on the ability of the Army to equip and move its forces to the battle and sustain them while they are engaged. Logistics provides the backbone for Army combat operations. Without fuel, ammunition, rations, and other supplies, the Army would grind to a halt. The U.S. military must be prepared to fight anywhere on the globe and, in an era of coalition warfare, to logistically support its allies. While aircraft can move large amounts of supplies, the vast majority must be carried on ocean going vessels and unloaded at ports that may be at a great distance from the battlefield. As the wars in Afghanistan and Iraq have shown, the costs of convoying vast quantities of supplies is tallied not only in economic terms but also in terms of lives lost in the movement of the materiel. As the ability of potential enemies to interdict movement to the battlefield and interdict movements in the battlespace increases, the challenge of logistics grows even larger. No matter how the nature of battle develops, logistics will remain a key factor. Force Multiplying Technologies for Logistics Support to Military Operations explores Army logistics in a global, complex environment that includes the increasing use of antiaccess and area-denial tactics and technologies by potential adversaries. This report describes new technologies and systems that would reduce the demand for logistics and meet the demand at the point of need, make maintenance more efficient, improve inter- and intratheater mobility, and improve near-real-time, in-transit visibility. Force Multiplying Technologies also explores options for the Army to operate with the other services and improve its support of Special Operations Forces. This report provides a logistics-centric research and development investment strategy and illustrative examples of how improved logistics could look in the future.

This book was released on 2016-08-09 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.
