New Generation Engines–The Commercial Transport Manufacturer’s Position 680276
Propulsion system requirements for subsonic and supersonic transports in the 1975 to 1985 period are presented from an airframe manufacturer’s point of view.
The number one problem will be noise, with different detail problems to be solved for subsonic and supersonic transports. With respect to engine cycles, it is shown that a new round of subsonic engines can be expected; for supersonic transports the cycle is needed which better matches both supersonic and subsonic flight requirements. A plea is made for the start of a long-range program aimed at understanding the fluid How details of unsteady compressor operation.
Total aircraft power requirements should be studied, allowing for new packaging concepts and certification rules. It is shown that opportunities exist which by 1975 may lead to practices significantly different from those now employed.
