Design and operational assessment of a low-boom low-drag supersonic business jet

There has been a worldwide interest to develop supersonic business jet (SSBJ) for minimum range of 4000 nm with low sonic boom intensity and high fuel efficiency. An SSBJ design model is developed in the GENUS aircraft conceptual environment. With model, low-boom low-drag concept designed optimized. This article studies its operational performances. The sustained cruise flight studied find out fuel-efficient Mach number altitude combinations. combined subsonic scenarios are evaluate feasibility boom-free routes. one-stop scenario compare consumption time advantage over airliners. off-design explore space assuming there would be limit future. Through studies, it revealed that corresponding most operating specific number. To operate near cutoff leads both increases (6.3%–8.1%) mission (11.7%–13.1%). business-class transport (231 g/PAX/km) consumes nearly three times as economic-class (77 g/PAX/km), which still far more than (20 g/PAX/km). Off-design reveal different trends against common understanding: does not necessarily decrease increases; decreases.
