摘要

With a growing gap between the growth rate of petroleum production and demand, and with mounting environmental needs, the aircraft in dustry is investigating issues related to fuel availability, candidates for alternative fuels, and improved aircraft fuel efficiency. Bio derived fuels, methanol, ethanol, liquid natural gas, liquid hydrogen, and synthetic fuels are considered in this study for their potential to replace or supplement conventional jet fuels. Most of these fuels present the airplane design ers with safety, logistical, and performance challenges. Synthetic fuel made from coal, natural gas, or other hydrocarbon feedstock shows significant promise as a fuel that could be easily integrated into present and future aircraft with little or no modification to current aircraft designs. Alternatives, such as biofuel, and in the longer term hydrogen, have good potential but pres ently appear to be better suited for use in ground transportation. With the increased use of these fuels, a greater portion of a barrel of crude oil can be used for producing jet fuel be cause aircraft are not as fuel flexible as ground vehicles.
