Aircraft Noise and Performance Data for a Notional Supersonic Business Jet

The International Civil Aviation Organization recently completed a study that determined the global environmental impact of adding several hypothetical supersonic aircraft types to the existing subsonic fleet. NASA supported this study by designing a notional 55-tonne supersonic business jet. The airplane is named the Supersonic Technology Concept Aeroplane by the international community. Performance, noise, and exhaust emission predictions for this transport were used to inform development of new environmental standards for future supersonic civil aircraft. The behavior of the aircraft in an operational setting is considered. Calculation of aircraft noise and performance data for this aircraft is the focus of this paper. Noise abatement departure procedures, stage length performance, and noise-power-distance data are determined using NASA tools. Also investigated are some of the anticipated behaviors and requirements of supersonic aircraft in the commercial airspace.
