Some Technical Aspects of Advanced Subsonic Transport Aircraft 650246

The objectives for NASA aeronautical research on commercial subsonic jet transport aircraft are outlined briefly. These objectives embrace reduction of landing speeds to enable use of smaller close-in airports, advancement of technology for higher bypass ratio turbofan engines to reduce noise and fuel consumption, and increase in force-break Mach number to improve cruise-flight efficiency. If the foregoing are realized, advanced transports with significantly better profitability and effectiveness than the current jets can be realized, perhaps by refurbishment of the existing fleets.
