D P Marsh: 1340. Design Considerations for Future Turboprop Transports. 1980.



Industry, under the sponsorship of NASA’s aircraft energy efficiency (ACEE) program, is taking a serious look at a new generation of propfan-driven passenger aircraft. Some preliminary design studies have been completed and a flight demonstrator program is being planned. This paper reviews the status and results of studies which are being performed at McDonnell Douglas toward defining a viable new generation of turboprop transports. The results of a study of a propfan-equipped DC-9 Super 80 show that a savings in average fuel burned per nautical mile of at least 20 percent may be realized for a near-term Mach 0.8 design turboprop.
