In order to pick up where the famous Concorde left off, the Boom Overture aircraft features a swept back delta wing and feuselage design profile that allows the aircraft to achieve a cruising speed of Mach 1.7 (2100 km/h). the Overture has an estimated wingspan of 52 meters in length and 18 meters in width. In terms of the wing design, (Singh & Dwivedi, 2022), described through their experiments that an aircraft with a swept back delta wing design yielded a better lift to drag ratio as compared to the standard delta wing design. Another advantage of having swept back delta wing design, as described by Pierre Sartre, where he analysed the Overtures predecessor, the Concorde, concluded that its swept delta wing design not only allows for supersonic travel, but also allows for better low speed controllability of the aircraft (Sartre, 1973). Other design features of the Overture such as the nonaxisymmetrical feuselage also aids it in achieving its top speed. According to (Makino, Suzuki, Noguchi, & Yoshida, 2003), a nonaxisymmetrical fuselage design reduces drag and sonic boom in low-sonic-boom airplanes, improving performance compared to low-drag and low-sonic-boom airplanes with axisymmetrical fuselages.
