A Parametric Exploration of Supersonic Business Jet Concepts Utilizing Response Surfaces

Market forecasts predict a potentially large market for a quiet supersonic business jet provided that several technical hurdles are overcome prior to fielding such a vehicle. In order to be acceptable, the QSJ must be able to fly at supersonic speeds over land and operate from regional airports while meeting government noise and emissions requirements. Physics based analysis tools are used in conjunction with a Response Surface metamodeling approach to create an environment in which the performance, economics, and environmental impact of the aircraft can be studied as a function of design and mission parameters. Through the use of this environment, the designer is able to rapidly explore the entire concept space by dynamically modifying the configuration, engine cycle, and requirements. Results obtained using this exploration tool indicate that it may be possible to meet emissions and noise requirements, but that technology infusion will be required in order to meet all performance and economic goals. Finally, this same physics-based environment was used to assess the impact of a portfolio of technologies on the system’s acceptability.
