Additional design studies of the NASA/Navy lift/cruise fan

摘要

Additional preliminary design studies were performed for a turbotip lift/cruise fan propulsion system for a Navy multimission aircraft. The LCF459/J97 propulsion system was previously designed for this application. These studies extended the analysis in areas of (1) scroll commonality, (2) increased engine-out contingency ratings, (3) mounting systems, (4) manufacturing cost reductions, and (5) vulnerability.
