TECHNOLOGY STATUS OF JET NOISE SUPPRESSION CONCEPTS FOR ADVANCED SUPERSONIC TRANSPORTS

This paper presents one aircraft manufacturer's views on the technology status of three of the most promising exhaust nozzle designs meeting the noise constraints: the coannular with plug, and the retractable mechanical suppressor. Each type is defined along with predicted operational characteristics. Theoretical and actual test performance, for both thrust loss and noise suppression, are summarized. Each of these three nozzles is combined with an appropriate engine, and is sized and integrated into a baseline Mach 2.2 supersonic transport to evaluate range performance. The current status of performance for the various suppression concepts is summarized.
