This book was released on 2018-06-12 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study documents the design and analysis of four types of advanced technology commercial transport airplane configurations (small, medium large and very large) with an assumed technology readiness date of 2010. These airplane configurations were used as a platform to evaluate the design concept and installed performance of advanced technology engines being developed under the NASA Ultra Efficient Engine Technology (UEET) program. Upon installation of the UEET engines onto the UEET advanced technology airframes, the small and medium airplanes both achieved an additional 16% increase in fuel efficiency when using GE advanced turbofan engines. The large airplane achieved an 18% increase in fuel efficiency when using the P&W geared fan engine. The very large airplane (i.e. BWB), also using P&W geared fan engines, only achieved an additional 16% that was attributed to a non-optimized airplane/engine combination.Daggett, David L. and Geiselhart, Karl A.

This book was released on 2004-02-20 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Research Council (NRC) of the National Academies was asked by NASA and the Office of Management and Budget to perform an assessment of NASA's Aerospace Technology Enterprise. The first such review, which began in early 2002, examined Pioneering Revolutionary Technology (now known as Mission and Science Measurement Technology). The assessment presented here, of the Aeronautics Technology Programs, began in early 2003 and is the second in the review series. The Aeronautics Technology Programs has three components: the Vehicle Systems Program, the Airspace Systems Program, and the Aviation Safety Program. To conduct this review, the NRC established three panels, one for each of the component programs. The NRC also established a parent committee, consisting of the chairman and a subset of members from each panel. The committee and panels comprised a cross-section of experts from industry, academia, and government and included senior-level managers and researchers in the aeronautics field. Biographical information on the committee and panel members is found in Appendix A. Review of NASA's Aerospace Technology Enterprise: An Assessment of NASA's Aeronautics Technology Programs contains the committee's assessment of the Aeronautics Technology Programs. Chapter 1 presents a top-level assessment, and Chapters 2 through 4 provide the assessments of the Vehicle Systems Program, the Airspace Systems Program, and the Aviation Safety Program, respectively.
