Improving the Efficiency of Engines for Large Nonfighter Aircraft

192 pages. library sticker on spine - no other markings, private collector Because of the important national defense contribution of large, non-fighter aircraft, rapidly increasing fuel costs and increasing dependence on imported oi l have triggered significant interest in increased aircraft engine efficiency by the U.S. Air Force. To help address this need, the Air Force asked the National Research Council (NRC) to examine and assess technical options for improving en gine efficiency of all large non-fighter aircraft under Air Force command. This report presents a review of current Air Force fuel consumption patterns; an anal ysis of previous programs designed to replace aircraft engines; an examination o f proposed engine modifications; an assessment of the potential impact of altern ative fuels and engine science and technology programs, and an analysis of costs and funding requirements.
