The PW-Allison 578-DX Propfan Demonstrator Propulsion System is being prepared for flight test by the Pratt and Whitney, Allison, and Hamilton Standard team. The demonstrator system consists of an Allison Model 571 power section, which is currently in service in industrial and marine applications, a new low pressure compressor, a new gear reduction system developed from an Allison/NASA program, a new propfan module, a new nacelle, and a full authority digital electronic control system. Preparation for flight testing includes comprehensive testing of the major components as 'building blocks', leading to complete propulsion system testing in an ambient test stand. Results of the test program are presented. Flight testing will be conducted in late 1987 on a McDonnell Douglas MD80 aircraft.
