NASA Lift Fan V/STOL Transport Technology Status

This paper is an overview of the status of lift fan transport technology. Selected results of recently completed NASA in-house and contractual research investigations are included within the general areas of lift fan transport design: propulsion, acoustics, integrated propulsion/airframe/aircraft control systems, piloted moving-base simulation, and aircraft aerodynamics. On-going NASA lift fan transport research is briefly summarized, and a possible next step in the overall program is suggested.
