The 578-DX Propfan Demonstrator Propulsion System, whose flight testing on an MD-80 airliner testbed was recently completed, has a powerplant encompassing a gas generator developed from engines currently used in marine and industrial applications, a novel compressor, a reduction-gear system developed under NASA auspices, a contrarotating propfan, a specialized nacelle, and a full-authority digital electronic control system. The flight test program has yielded data on (1) near- and far-field acoustic data to assess FAR36 Stage III conditions compliance; (2) data useful in the resolution of aircraft/engine integration problems; and (3) data suitable for guiding future geared propfan propulsion system development decisions.
