Design of a lift fan engine for a heavy lift aircraft

Abstract

e lift fan engines. The modification is important because a design that uses current technology is more likely to be brought into service in the near future. This thesis documents the process required to use current technology in a lift fan engine for a heavy lift aircraft. The process uses current software and focuses on the design of the following components: the powerplant, the transmission shafts and the lift fan. The result is a propulsion system which allows a 185,000 lb aircraft to takeoff vertically as well as cruise at speeds greater than Mach=0.6.
