SUMMARY

Table 1-2 illustrates that the subject of modifying engines and re-engining aircraft for various reasons has been studied extensively. However, two factors distinguish this study from the previous studies: (1) the selection of candidate systems herein is based mainly on their ability to reduce the Air Force fuel burden and (2) consideration is given to the entire fleet of large nonfighter aircraft. The following chapters analyze in depth the methodology for selecting the candidate systems for modifying engines and re-engining aircraft; additional factors that may reduce aircraft fuel consumption; promising alternative fuels and engine developments that may one day impact fuel consumption; and innovative contracting and financing approaches that the Air Force may employ with industry to reduce engine development and sustainment costs.
