Aircraft Engine Future Fuels and Energy Conservation.

摘要

Future fuel supplies for aviation is an important matter. If the world continues to consume its petroleum resources at its current rate of consumption, it will essentially run out of these resources by the turn of the century. The need for aircraft fuel conservation is most urgent, if not mandatory, because the future of aviation as we know it today, is at stake. This lecture series is designed to provide various interested members of NATO with a better understanding of the problems facing the aerospace community and to provide an opportunity to review and assess what steps can and are being taken to alleviate this international problem. Current and forecasted world energy demands, growth, and supply are reviewed in perspective to the status and outlook for future aviation fuels to meet NATO needs. The special problems associated with the refining of aviation fuels from lower quality feedstocks (including fuel refined from coal, oil shale, and tar sands) and techniques for reducing energy consumption in refining processes are examined. Special attention is given to the chemistry and combustion characteristics of future hydrocarbon fuels and the impact of using these fuels in aircraft engines and fuel systems. An assessment is made as to what technology advancements are underway and what other advancements are needed with reference to engine components, engine systems, aircraft designs and operational procedures to help conserve fuel resources.
