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.

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.

Examines the 1984 "war" that pitted Pratt and Whitney against GE in head-to-head competition for multi billion dollar defense contracts to provide high performance engines for front line fighter aircraft. The circumstances surrounding the lengthy battle led to the Air Force decision to split future engine sales between the two. Attempts to cut through emotional opinions of the "combatants," to report reality, and to identify lessons learned. Helps the reader to understand the government-to-contractor personality issues; to understand management styles, business expectations and communication skills of key participants.

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

The propulsion system is arguably the most critical part of the aircraft; it certainly is the single most expensive component of the vehicle. Ensuring that engines operate reliably without major maintenance issues is an important goal for all operators, military or commercial. Engine health management (EHM) is a critical piece of this puzzle and has been a part of the engine maintenance for more than five decades. In fact, systematic condition monitoring was introduced for engines before it was applied to other systems on the aircraft. Diagnostics and Prognostics of Aerospace Engines is a collection of technical papers from the archives of SAE International, which introduces the reader to a brief history of EHM, presents some examples of EHM functions, and outlines important future trends. The goal of engine health maintenance is ultimately to reduce the cost of operations by catching problems before they become major issues, by helping reduce repair times through diagnostics, and by facilitating logistic optimization through prognostic estimates. Diagnostics and Prognostics of Aerospace Engines shows that the essence of these goals has not changed over time.

Few technological advances have affected the lives and dreams of individuals and the operations of companies and governments as much as the continuing development of flight. From space exploration to package transport, from military transport to passenger helicopter use, from passenger jumbo jets to tilt-rotor commuter planes, the future of flying is still rapidly developing. The essays in this volume survey the state of progress along several fronts of this constantly evolving frontier. Five eminent authorities assess prospects for the future of rotary-wing aircraft, large passenger aircraft, commercial aviation, manned spaceflight, and defense aerospace in the post-Cold War era.
