Energy Efficient Engine Program Technology Benefit/Cost Study. Volume 2

摘要

The benefit/cost study to identify turbofan engine technologies required for the years 2000 to 2010, the benefits of those technologies were formulated, and programs for developing the technologies required for that time period were formulated. It is shown that there are still many potential benefits to be realized from the advancement of gas turbine engine technology. Preliminary technology concepts that might be amenable to future development were ranked. Cycle studies, flowpath definition studies, and mechancial configuration studies were used to identify and establish the feasibility of the technologies that would be required in the 2000 to 2010 time frame. It is shown that a turbofan engine with advancements in aerodynamics, mechanical arrangements, and materials offers significant performance improvements over 1988 technology. The benefits of the technologies are assessed using fuel burn and direct operating cost plus interest (DOC+I).
