The updated and expanded third edition of this book focuses on the multi-disciplinary coupling between flight-vehicle hardware alternatives and enabling propulsion systems. It discusses how to match near-term and far-term aerospace vehicles to missions and provides a comprehensive overview of the subject, directly contributing to the next-generation space infrastructure, from space tourism to space exploration. This holistic treatment defines a mission portfolio addressing near-term to long-term space transportation needs covering sub-orbital, orbital and escape flight profiles. In this context, a vehicle configuration classification is introduced covering alternatives starting from the dawn of space access. A best-practice parametric sizing approach is introduced to correctly design the flight vehicle for the mission. This technique balances required mission with the available vehicle solution space and is an essential capability sought after by technology forecasters and strategic planners alike.

Some marine propulsion systems are based on thermal machines that operate under the diesel cycle. Their main advantages, compared to other propulsion systems based on thermal machines, are low specific fuel consumption and greater thermal efficiency. However, their main disadvantages lie in the emissions produced by combustion, such as carbon dioxide (CO2), sulfur oxide (SOx), and nitrogen oxide (NOx). Over the last decade, the International Maritime Organization (IMO) has adopted a series of regulations to reduce these emissions based on the introduction of several energy efficiency designs and operational indicators. In this context, this book focuses on the design and operation efficiency of ships through an analysis of the main propulsion systems. It discusses the use of alternative fuels as well as the integration of hybrid and fully electric propulsion systems.

The U.S. Navy is currently in the process of designing its next generation aircraft carrier, termed CVX. One technological advance for the CVX, compared with the current Nimitz class of carriers, is a new propulsion system. To help in deciding between a nuclear and non-nuclear propulsion system for CVX, the Navy asked RAND to determine the effects of the CVX propulsion choice on the industrial bases supporting nuclear propulsion systems and those supporting conventional propulsion systems. RAND began the research in April 1998 and, because of the time frame of the CVX propulsion system decision, provided the results of the analyses to the CVX program office in August 1998. Shortly thereafter, the decision was made that the CVX class would use nuclear propulsion. The research findings described in this document helped influence that decision. This document offers the briefing presented to the program office along with accompanying annotation. The research was based on understanding the various propulsion system options being considered and contacts with suppliers and integrators of key system components to establish how a CVX decision would affect their company and their industry, as well as other Navy programs. This research and its documentation should be of interest to the Office of the Secretary of Defense (OSD) and Navy policymakers and planners who must face the propulsion system decisions for future Navy ship programs. It may also interest industrial decisionmakers involved in construction and supply of Navy ships and parts.

Rocket and air-breathing propulsion systems are the foundation on which planning for future aerospace systems rests. A Review of United States Air Force and Department of Defense Aerospace Propulsion Needs assesses the existing technical base in these areas and examines the future Air Force capabilities the base will be expected to support. This report also defines gaps and recommends where future warfighter capabilities not yet fully defined could be met by current science and technology development plans.

Energy and Sea Power: Challenge for the Decade is a collection of essays, which were presented as lectures at the Eighth Annual Pacific Coast Sea Power Forum, held at the U. S. Navy Postgraduate School at Monterey, California, in October 1980, covering the topic of energy and sea power. The book contains papers on world energy availability, its use and economic impact, and on more specialized topic areas such as environmental protection, ship construction for energy efficiency, and the question of renewable ocean energy resources. The text also presents papers on the regulatory and environmental aspects of ocean energy activities; the directions over old sea lanes; and marine transportation needs for U.S. energy supply; energy. The military applications and implications of ocean thermal energy conversion systems; the ocean engineering needs for U.S. energy supply; and the energy-efficient ship design are also considered. The further presents a paper on the shipbuilding needs for support of ocean-energy development.
